Chapter XIX: Part 19

The tongue is also subject to gradual and permanent enlargement. A remarkable case of this nature occurred to me some years ago, and I shall here detail it shortly. The patient was a male, aged 19. The tongue was of a very large size, compressible and elastic, projected three or four inches from the lips, and completely filled the cavity of the mouth. It was of a dark brown hue, in some places livid; its surface was rough, at some points granulated, at others fissured, and at many traversed by large venous trunks. At the back part of the dorsum, the papillæ were much enlarged, granulated points were numerous, and several plexuses of dilated blood vessels ramified immediately beneath the investing membrane. There was occasional bleeding from an ulcerated fissure near the centre of the dorsum, and also from the lateral parts of the protruded portion: in the latter situation, several cicatrices were visible. Saliva flowed in a continuous stream from the apex of the tumour. The lower jaw, much separated from the upper, was elongated and unusually narrow; the teeth, particularly those in front, were placed at a distance from each other, were covered with tartar, and projected almost horizontally from the sockets. A depression was felt at the symphysis mentis, as if the two portions of the jaw were asunder, and the intervening space occupied by ligamentous matter. The enlargement was congenital, and the organ swelled rapidly, it was stated, every three months to a much larger size, and subsided gradually. The bleeding was most frequent and profuse when the swelling was greatest, and then too he suffered much pain in the part. Articulation was very indistinct, and could be understood only by those who were accustomed to be near him. He swallowed, and even masticated pretty freely. From the periodical enlargement and diminution, from the repeated hemorrhages, and from erectile tissue being visible on many parts of the surface, I considered the structure of the tumour to be in part similar to that of aneurism by anastomosis, and to be throughout extremely vascular. I therefore did not attempt removal by incision, but in the first instance intercepted its vascular supply by tying both lingual arteries. The tumour was not affected immediately on the application of the ligatures, but soon began to diminish gradually. Everything was proceeding favourably; but, on the seventh day, the tongue was attacked with inflammatory swelling, which advanced unsubdued, notwithstanding the most active treatment. Sloughing commenced at the apex, and appeared extending backwards; I then isolated the protruded portion of the organ by ligature, and thus removed it in three or four days. At that time he complained of no pain, and felt very comfortable. But his system became much disordered soon after; abscesses formed rapidly over both wrists and on the hands, unhealthy infiltration of the cellular tissue took place at the root of the tongue, and amongst the deep muscles at the upper part of the neck, the parts became gangrenous, and he died. Dissection showed that the greater part of the tumour was composed of erectile tissue. A sketch of the lower jaw is here appended, in order to show the alteration in form, both at the symphysis and in the rami, which had resulted from the pressure of the organ and the necessarily constant open condition of the mouth.

Enlargement of the tongue occasionally takes place in young subjects, a sort of simple hypertrophy, which often proceeds to a very great extent. The increase goes on in a remarkable manner after the organ is extruded beyond the lips, so that the patient is incapable of covering it. Portions of the swelling of a V shape have been removed in such cases, and the edges of the wound put together. But by well managed and continued pressure the absorption of the swelling has been brought about, the organ has been reduced within the oral aperture, and a cure has then rapidly followed.

_Division of the Frænum Linguæ_ is sometimes, though rarely, required. Division can be necessary only when the frænum is so short as to confine the point of the tongue, prevent free motion of the organ, and thereby cause indistinctness of articulation. Infants are often supposed by anxious mothers to have their tongues unduly confined, when no such malformation exists; in such circumstances, it is almost needless to observe that the part ought not to be interfered with. And even when there is confinement, division should not be had recourse to, unless the child is prevented from taking nourishment. The operative procedure is simple and safe. The tongue is raised towards the palate, either by a spitula or split card—or, what is better, by the fingers—and the frænum is cut across to a sufficient extent by blunt-pointed scissors.

_Ranula_ is a swelling produced by accumulation in, and distention of, the extremity of the combined ducts of the sublingual and submaxillary glands. The extremity of the duct contracts, or is completely closed, and in consequence of the saliva and mucus (the one the secretion of the gland, the other of the duct) collect, distend the canal, and cause thickening of the parietes. Thereby a tumour is formed, which, in some instances, attains a very large size, displacing in some measure the neighbouring parts, and incommoding the tongue in particular. Indistinct utterance and impeded deglutition result.

The orifice of the duct, if discovered, is to be dilated gradually by occasional introduction of variously sized probes. Often it is necessary to make a small incision in the situation of the orifice, and introduce a bit of gum-elastic bougie, by continuing the use of which for some time, permanency of the opening may be obtained.

_Deposition of Earthy Matter_—principally phosphate of lime—not unfrequently takes place in the extremity of the submaxillary and sublingual ducts, and the concretion so formed is often of considerable size; some are larger than an almond. The colour is either white or yellowish, and the surface either smooth or roughened by nodules; in all the calcareous matter is friable, and disposed in concentric layers. They are of the same nature as the earthy deposits, called tartar, which form on those teeth opposite to the extremities of the salivary ducts. The foreign body produces uneasiness in the mouth, swelling, and indistinctness of speech; occasionally painful swelling of the salivary gland and surrounding parts takes place. Concretions also form, though very rarely, in the extremity of the parotid duct, and are attended with like inconvenience; of this I have seen only two cases.

The foreign body is easily removed; an incision is made through the membrane of the mouth, and the concretion dislodged by forceps, a scoop, or the fingers. The saliva regains its course, and irritation subsides. Sometimes the foreign body is exposed by ulceration, and might ultimately escape from its bed spontaneously.

A figure of a salivary calculus of considerable size is here given. When the concretion is small, its extraction is not so easily accomplished as might be supposed. It is apt to slip back out of reach, so that it cannot be seized, brought forward and extracted either by scoops or forceps. The flow of saliva must be promoted by giving the patient something to masticate; the probability is, that the foreign body will then be presented, and perhaps expelled, if the opening of the duct has been previously dilated. A young lady was brought to me lately suffering great uneasiness from the presence of a concretion, not larger than a millet-seed. She complained of great pain under the jaw on seeing anything savoury, that, as the vulgar phrase is, made her mouth water. Various unsuccessful attempts had been made to remove it. A small incision of the surface of the duct was made, but the foreign body eluded the grasp of the forceps, and completely disappeared. The patient was given a bit of bread to chew, and almost immediately the concretion was expelled.

_Tumours_, unconnected with the salivary ducts, occasionally form in the loose cellular tissue under the tongue. They may be either sarcomatous or encysted; the former are rare. I have removed several solid tumours, principally adipose, from this situation. They were loosely connected, and taken away without almost any dissection; indeed they were lifted out with the fingers, after division of the membrane of the mouth and of the cellular cyst which surrounded them. One was as large as an orange, and of a flattened form. The tongue had been displaced by the swelling, and articulation, deglutition, and breathing impeded. The patient, an old lady, had a good recovery. The case had been by some mistaken for ranula; and I mention this circumstance, lest others may reckon more on the situation of a swelling, than on its feel and other external characters. A sketch of the tumour is given at page 137.

Encysted tumours below the tongue are common. The cysts are generally thin and adherent, the contents albuminous and glairy. They attain a large size, and prove very inconvenient. Occasionally the cysts are thick and more loosely attached; such usually contain atheromatous matter. I removed one uncommonly large, from the inner surface of which numerous hairs were growing.

Encysted tumours here can seldom be removed by dissection; the depth of their situation, their firm connexion, the awkward situation in which the patient is necessarily placed, and the risk of hemorrhage, forbid the surgeon from attempting regular extirpation. A more simple and equally effectual procedure is as follows:—The membrane of the mouth and the cyst are divided by the point of a bistoury; and if the tumour be large, and the distention great, an oval portion of the parietes may be cut out. The contents are thus evacuated. The bleeding is allowed to cease, and the cavity having been wiped out clean, a stick of caustic potass is applied to the surface, so as to annihilate the cyst effectually. This I believe to be the only radical and safe mode of removal; after any other, the tumour is certain to be reproduced. It has been recommended to pass a seton, so as to excite inflammatory action, and lead to obliteration of the cyst. I have made trial of this practice, but most dangerous swelling ensued, the mouth was rapidly filled, and the system alarmingly shaken; after all the disease was not eradicated.

Tumours beneath the tongue, however originating, occasionally inflame, and become the seat of unhealthy abscess. A large and painful swelling forms, and projects under the chin. The matter gradually approaches the surface, and perhaps evacuates itself imperfectly into the mouth, or the integuments give way, and afford an external issue. In such cases, an early incision from the mouth may prevent the internal mischief, and the disfiguration of the countenance which would otherwise ensue may, in short, limit the suppuration; at a later period a free opening requires to be made below the chin, in the mesial line, and in the direction of the muscular fibres. A ready drain is thus obtained for the matter, and the cavity of the abscess gradually contracts.

_Tumours of the Gums_ are usually hard, and not inclined to increase rapidly. They are of the same consistence as the parts to which they are attached, and grow either inwardly, outwardly, or both. They surround one or more teeth, which at last become loose, the alveolar processes then soften, and form part of the swelling.

These may degenerate, and grow rapidly, or the tumour may be soft (tumor mali moris) from the first. The attention of the patient is directed to the part by the occurrence of discharge from about the teeth, which loosen one after another. A soft tumour arises from the sockets after either extrusion or extraction of the teeth, it grows rapidly, and involves more and more of the gums and alveolar processes. Angry ulceration attacks the prominent parts of the swelling; the bone is softened to a considerable extent around; the discharge is thin, bloody, and profuse. Ultimately the lymphatics become affected, neighbouring parts are contaminated, malignant action acquires a firm footing, and extends, the patient becomes hectic, and dies.

Each kind of tumour should be removed freely and early; the untoward results of the latter have been already mentioned; and I believe that, if the former be allowed to proceed unchecked, the tumour may ultimately extend to the bone, and osteosarcoma of the jaw, more or less extensive, be established. The disease must be attacked at an early period of its existence, and teeth, sockets, and soft parts taken freely away, by means of a strong knife and saw, or cutting forceps. After excision, the actual or potential cautery should be applied, otherwise the disease is apt to recur. Portions of involved bone, which may have escaped the knife, are by the caustic made to exfoliate. When the potassa fusa is used for the purpose of destroying what cannot be readily reached by the knife, and when it is pushed into the alveoli and applied to the altered gum, its action must be limited by the immediate use of vinegar, diluted or not.

_Inflammation of the gums_ and neighbouring parts is attended with violent pain, swelling, and throbbing, difficulty in opening the mouth, headache, and fever. Inflammation of the soft parts runs its course speedily, and, as the cause is seldom removed during the existence of the inflammatory action, generally terminates in suppuration, so giving rise to what is termed _parulis_ or gumboil. Frequently the inflammation extends to the sockets of the teeth, which seldom resist the action long, but from their low degree of vitality soon become necrosed; and by the presence of the dead portions of bone, a fresh accession is given to the disease. Severe pain is experienced on touching the teeth whose alveoli are affected; they project and become loose; purulent matter is secreted, and oozes out between the loosened teeth and diseased gums. Abscesses form, and point in different situations; the gums are tumid and spongy; through the openings in them the bone can be felt bare, and the purulent matter is situated within or around the alveoli, and under the mucous membrane and cellular tissue which invest them.

When the inflammation has been either intense from the first, or of long duration, it not unfrequently happens that abscesses form within the substance of the jawbone, and occasionally to a considerable extent—a portion of the bone having become inflamed, and the action terminating in suppuration and partial caries. This is more apt to occur in the inferior than in the superior maxillary bone; and, if allowed to proceed, the osseous cyst containing the purulent matter gradually enlarges, the plates of the bone are separated and expanded, the parietes become attenuated, and the affection is termed spina ventosa. Purulent collections in this situation also seem, in many instances, to arise from, or at least to be preceded by, the formation of a cyst around the decayed root of a tooth. Such cysts are generally of small size, and pyriform shape; externally they are smooth, membranous, and of rather a delicate texture; internally, they are lined by lymph of soft consistence, and contain purulent matter. In fact, they are purulent depôts, which form in consequence of inflammation around the fangs of the teeth, and from which the matter is occasionally discharged through a small aperture at the upper part of the cyst, and by the side of the affected tooth. They sometimes attain a very considerable size.

Mercury is perhaps the most common cause of this disease; but it is also produced by certain operations on the teeth, and by the presence of carious teeth or of stumps.

_Caries of the teeth_ is an extremely common affection, and in some instances seems to arise from an unhealthy state of the constitution; but it is most frequently produced by the teeth having suffered from chemical agents, as when the mineral acids have been taken for a considerable time as medicines, or when the individual is in the habit of consuming sweetmeats, and confections. Sometimes the disease remains almost stationary, and may give little or no annoyance for a number of years; in other instances, its progress is very rapid. A portion of the tooth gradually decays, and this is at first unattended with any uneasy sensation; but when, from continuance of the destructive process, the central cavity has been exposed, the pain is excruciating, attended with headache, and swelling of the surrounding soft parts. In general, the progress of the disease may be arrested by removing the diseased portion, and stuffing the cavity, before any pain has been felt. But after the central cavity of the tooth has been exposed, filled with fungous mass, as here seen, or from their growing in a faulty direction, and pain consequently experienced, the most effectual remedy is extraction. The patient from whom the specimen below was obtained, perished in consequence of the extensive abscesses of the mouth and neck, consequent upon the awkward position of the wisdom tooth.

From the presence of carious teeth, or decayed portions of teeth, many evils both local and general ensue, besides inflammation and abscess. They are frequently the cause—and the sole cause—of violent and continued headaches; of glandular swellings in the neck, terminating in, or combined with abscess; of inflammation and enlargement of the tonsils, either chronic or acute; of ulcerations of the tongue or lips, often assuming a malignant action from continued irritation; of painful feelings in the face, tic doloureux, pains in the tongue, jaws, &c.; of disordered stomach, from affection of the nerves, or from imperfect mastication; and of continued constitutional irritation, which may give rise to serious diseases.

Along with abscess of the gums, purulent matter often collects in the cellular tissue of the cheek or of the chin. In the latter situation, the inflammation and suppuration are often caused by the teeth in the front or side of the lower jaw being too much crowded together. When the teeth are crowded together, the patient, of course, cannot be effectually benefited till one or more of them are extracted, and sufficient space allowed for development of the others. The abscess gives way, and discharges its contents often both externally and internally, and a fistula remains, which cannot be got rid of, unless, as in most other affections, the cause be removed. The cavity of the abscess must be opened into either from without or within, and after the subsequent irritation has subsided, the cause must be removed; carious teeth or stumps are not to be taken away during the inflamed state of the parts, but after the pain and inflammation has subsided in consequence of free evacuation of the purulent matter. After these have abated, and not till then, the offending bodies are to be extracted, both in order to procure a more speedy and effectual cure, and with a view to prevent recurrence of the disease. If a portion of the jaw has become necrosed, the sequestra are to be extracted as they become loose, and openings and counter-openings must be made, according to circumstances, so as to afford a free outlet to the matter.

The extraction of teeth, the crowns of which have not been destroyed, is accomplished most readily by the dexterous use of variously shaped forceps. Stumps may be occasionally extracted also by forceps, but the lever is generally required to loosen them from their sockets. The old key instrument and pelicans are now superseded by those above mentioned.[37]

_Spina Ventosa of the Jaw_ often originates, as before mentioned, in a small cyst at the root of a decayed or dead tooth. An enormously large one extracted along with the stump attached is here shown: it is sketched from a specimen in the collection of Mr. Nasmyth, of Edinburgh.

The disease is usually situated on one side of the lower jaw; but sometimes occurs in the upper, and is at first unconnected with the cavity of the antrum. Inflammation has taken place in the internal structure of the bone; matter is secreted by the medullary vessels, and collects in the cancellated texture. Purulent formation advances, the cancelli are broken down, the external laminæ of the jaw are extended, protruded, and attenuated; and then the internal cavity enlarges, containing pus, perhaps mixed with other fluids, and with disorganised particles of bone. Sometimes the collection proceeds slowly, and the expansion of the bone is gradual and uniform; in other instances, the swelling rapidly attains a large size. As the disease advances, the bony parietes become remarkably thin and delicate, particularly at the more prominent parts of the tumour; and at many points bone is deficient, and its place supplied by membranous expansion. Occasionally alteration of structure takes place in the cyst; solid matter is added, either bony or fibro-cartilaginous, and morbid action proceeds in the new deposit. In acute cases, in which the secretion and distension are rapid, severe pain is felt in the part at the first, and usually continues but little unabated; when the swelling is slow and gradual, considerable pain is experienced during the inflammatory stage, but soon diminishes, or ceases entirely. In every instance, the features are deformed, and the functions of the mouth more or less impeded.

Osteosarcoma may supervene on spina ventosa—morbid action occurring in the parietes, and morbid deposit ensuing, as in the following instance:—The patient was a male, aged twenty-one. Swelling had existed for a considerable time at the posterior part of the lower jaw on the left side. The wisdom tooth and last large grinder, their pulps probably having been blighted, never appeared, and the swelling occupied their situation. The bone was expanded on each side; the upper surface of the tumour was soft, its growth had been gradual, and no great pain or uneasiness was experienced. I cut out an oval portion of the cyst where it projected into the mouth, and well-digested matter was evacuated; a seton was then passed out near the angle of the jaw, and worn for some weeks. The plates of the bone approximated, the cavity contracted, and the discharge ceased. Two years afterwards rapid swelling took place in the same situation, suppuration occurred, and the matter was again discharged by incision; the tumour then subsided. Again inflammatory swelling occurred twelve months afterwards; the same course was followed and the patient relieved. A hard swelling now occupies the jaw from its angle to the canine tooth, it is increasing in size; the necessity for its removal is apparent, and has been decided upon. Very shortly after writing the above, the patient submitted to the disarticulation and removal of fully half of the jaw, represented here. He made a rapid recovery, and showed himself to me and the pupils at the hospital a short time since, and fully five years from the time of the operation, in remarkably good health, and very little deformed by his loss. His whisker effectually conceals the mark of the incisions.

But in general, after free evacuation of the purulent matter from a bony cavity, even of very large size, the space between the parietes diminishes rapidly, the distended and attenuated bone contracts and is condensed, the new deposition is absorbed, and the parts regain their natural and healthy appearance.

In the slighter cases of spina ventosa, removal of the offending teeth or portions of teeth, is generally sufficient; the matter escapes freely enough from the sockets, and the discharge soon ceases. When the cavity is considerable and its parietes thin, a counter-opening at the base of the jaw is required; and it is often of advantage to introduce a small cord from the opening in the mouth through the counter-opening, and to continue its use for a short time, drawing it backwards and forwards in the cavity occasionally. For making the counter-opening and placing the seton at the same time, a strong needle in a fixed handle is most convenient. This practice I have employed in a good many instances, and can confidently recommend as successful. In a large spina ventosa, not complicated with solid growth, the parietes may be removed freely and with safety; the cavity is dressed to the bottom, and gradually fills up by granulation. The division of the integuments to expose the tumour must vary according to the circumstances of the case; the incision of the bone will generally be accomplished by a strong bistoury. Such procedure will seldom fail in procuring a cure, and is less severe, less dangerous, and productive of less deformity, than division of the jaw and entire removal of the diseased portions, an operation which can very seldom be warranted for spina ventosa. In the following case, the tumour was the largest of this kind which I have met with in the jaw, and yielded to the treatment just noticed. The patient was a male, æt. 48; he applied to me in 1821. The tumour had been of three or four years’ duration, equalled a large fist in size, and involved the left side of the lower jaw at the junction of the ramus with the body of the bone. The sac extended behind the coronoid process, and downwards, through the substance of the jaw, amongst the hyoid muscles. Several carious teeth and stumps were imbedded in the swelling; the projection was chiefly lateral, the parietes were yielding, and the line of the jaw could be traced from below. There was occasional slight discharge of purulent matter from the neighbourhood of the involved teeth. The cheek was laid open, and the bony and cartilaginous parietes of the cavity completely removed; the bleeding from the bony surface was arrested by cautery and pressure.

The soft parts united kindly, and the patient obtained a rapid, perfect, and permanent cure, returning home with the cheek united in ten days after the operation.

_Solid Tumour_ of the Lower Jaw—_Osteosarcoma_—commences in the internal structure of the bone, frequently in the neighbourhood of stumps. The origin may be traced to external injury of the part; or the disease may take place in the jaw, either along with osteosarcomatous tumours of other bones, or subsequently to their development; in such circumstances a peculiar disposition of the system is the only cause that can be assigned. The tumour generally occupies the lateral parts of the bone. Its growth may be either slow or rapid, and is attended with dull uneasiness, rather than acute pain. At first the morbid deposit is confined to the cancellated texture, but as it increases the external laminæ are distended, and at last give way at one or more points, and the tumour protrudes fungous into the mouth. The consistence of the mass is various, it may be soft and brain-like, or cartilaginous, mixed with bone and fibrous matter in various proportions; but the anatomical characters of these tumours have been already detailed, and need not be here repeated. The features are much deformed, the swelling seriously incommodes the neighbouring parts; the teeth loosen and drop away, and fungi arise from the sockets; a fetid, thin, sometimes bloody discharge is secreted copiously, and the health declines. The part protruding around the gums is deeply indented by the teeth of the upper jaw; it separates the jaws to a greater or less extent, prevents closure of the lips, induces salivation, and impedes the taking of nourishment. The tumour is one of those which are apt to be reproduced, and if unmolested, gradually undermines the system, and ultimately the patient perishes very miserably. At one time every instance of it was regarded as hopeless; but of late a great many tumours, in various stages of advancement, have been removed successfully by British and foreign surgeons. In some instances, the portion of the jaw containing the morbid growth has been sawn out; in others, one half of the bone, or more, has been removed by disarticulation, after being divided beyond the diseased part. A very few weeks ago, I had occasion to remove fully three-fourths of this bone, from the site of the first large molar on the left side to the condyle of the right. The patient, an elderly female, is convalescent. The operation is severe, and to a spectator shocking enough; but it can be undertaken with safety, and in most cases with almost a certainty of favourable termination. In no other way, assuredly, can the disease be eradicated. Partial excisions, applications of the cautery, &c., only hasten the malignant process.

To expose the tumour and admit of the bone being readily divided, incision of the soft parts requires to be extensive. And previously to determining on the plan of operation, the extent of the disease must be ascertained accurately. If, for example, the tumour is included between the lateral incisor tooth and last molar on the same side—these teeth must be extracted to permit division at these points. A semilunar incision may then be made along the base of the jaw, the horns of the incision pointing upwards and passing over the space which was occupied by the extracted teeth. The flap is dissected up, and the membrane of the cheek divided along the line of incision. The bistoury is then carried along the inside of the bone so as to divide the membrane of the mouth and separate the attachments of the muscles. The tongue is pushed aside, and a copper spitula placed under the jaw at the part to be divided, in order that the soft parts may not be injured during the sawing. A small narrow saw, or one commonly known by the name of Hey’s, is applied to the bone at the points where the teeth were extracted, and by a few motions of this instrument a notch is made of no great depth; a pair of strong cutting pliers are placed in the track, and by them division of the bone is accomplished with equal neatness, and much more rapidly than if the use of the saw had been continued. The pliers should be strong in every point, and the handles long, to afford the advantage of a powerful lever. In edentulous subjects, as the one alluded to above, there is no necessity for using the saw at all: the bone is at once and easily cut by the forceps. The chain saw has been recommended for performing the section of the bone, but I have not yet seen one to be depended on; it is not only slow, but uncertain, in its operation.

The incisions may be made otherwise. The cheek may be divided by passing through it a long narrow bistoury, close to the anterior edge of the masseter muscle, and carrying the instrument forwards and through at the angle of the mouth. From each extremity of this incision another is made downwards, the anterior one inclining forwards, the other backwards. By reflection of the flap thus formed, the bone is exposed more easily, rapidly, and perfectly, than by the former mode of incision. The objection to this mode of procedure is the deformity occasioned by the scars, though, if care is taken in putting the edges together, this is very slight indeed, and not remarkable.

In either method, no artery, except the facial, requires to be secured by ligature. After division of the bone, the attachments of the tumour, which may not have been separated previously, are cut with the bistoury, the cavity is filled lightly with charpie, and the incisions are carefully and neatly put together, and retained by points of interrupted and twisted suture; the latter form of suture being adopted at those points where accurate coaptation is most important.

The _symphysis_ of the lower jaw has been removed, and its extirpation may again be rendered necessary, either on account of tumour commencing in its internal structure, or from disease of the sockets extending deeply and approaching the base. I removed it in a case of malignant disease, by which, and by the applications used as remedies, great ravages had been made on the under lip; the gums and alveoli were involved, as also the bone, to a considerable extent, without any apparent affection of the lymphatics. Nothing untoward occurred in the operation, and the case was proceeding favourably; but after some weeks the patient was seized with violent erysipelas of the face and head, and perished. One objection to the operation is, that the muscular attachments of the tongue to the symphysis cannot be divided without some risk; the antagonist muscles are unrestrained; the os hyoides and root of the tongue may be drawn backwards upon the forepart of the vertebræ, so as to close the air-passage, and cause suffocation. This is guarded against by the introduction of a thick ligature. The disposition to retraction soon ceases.

Disarticulation of one side of the jaw is not unfrequently necessary; it is absolutely required when the tumour encroaches upon and involves the angle and ramus. It is a more severe operation than excision of part of the bone, and attended with greater risk; yet it may be advised and undertaken with a very fair and probable chance of ultimate success. The incision of the cheek is made to incline more upwards than those recommended for partial excision, and is extended to over the articulation of the jaw; from this point, another is made in the direction of the ramus, and prolonged an inch or more beyond the angle. A third incision is made perpendicular to the first, or to the lower lip, over that part of the bone in front which is to be divided. The flap is turned down, and the muscles and membrane of the mouth separated from the bone opposite to the last incision; after which, the finger is passed through to complete the detachment. A preferable form of incision along the posterior border of the ramus and under the base of the jaw and tumour to over the point at which the bone is to be sawn, but without division of the lip, is recommended in the _Practical Surgery_. This method I have practised repeatedly; the cicatrix is then completely out of sight, and in the male is entirely covered and concealed. During the cure, also, the discharges escape more readily, the opening being quite dependent. The bone is then divided at that point by the saw and pliers, the tooth in the line of the track having been extracted previously to the commencement of the operation. The cut end of the jaw is laid hold of by the left hand, and depressed, and the bistoury carried backwards along the internal surface, to effect detachment as far as the angle. The bone is still more depressed, and the temporal muscle cut from the coronoid process. The mass is thus loosened, and forced downwards and backwards on the neck; the forepart of the capsule is then cut, and the bone twisted out. Separation of the remaining attachments is completed by a few rapid strokes of the knife, and the whole mass removed. Hemorrhage is then to be permanently arrested, but instead of immediately tying every open mouth which presents itself, it is sometimes better to expose the common trunk of the internal maxillary and temporal arteries—which is easily effected, as it emerges from under the digastric muscle—and to pass a ligature beneath it, by means of an aneurism needle. This is more quickly done than the applying of ligatures to the many branches of this trunk which have been divided. The other vessels—the facial, branches of the lingual, &c.—are then tied, the cavity is filled with charpie, and the incisions of the soft parts are carefully closed. In these, union by the first intention usually takes place nearly throughout the whole extent; suppuration occurs from the deep wound; the charpie is dislodged gradatim, and removed; granulations spring up; and, after some time, the cavity is obliterated. The cheek must necessarily fall inward very considerably, but the deformity is not to be compared to that caused by the tumour. During granulation, the patient is made comfortable by the frequent use of tepid gargles, lodgement of pus in the mouth being thereby diminished. Articulation and mastication are not so perfect as when the jaw was entire and sound; but the patient gradually becomes accustomed to the want, and these functions improve. A contrivance described in the _Practical Surgery_ is used to prevent the remaining portion of jaw from being drawn towards the mesial line, and to keep the teeth opposite to those of the corresponding side of the upper jaw. Partial paralysis of the side of the face necessarily follows, for there is no possibility of accomplishing disarticulation of the jaw without dividing many branches of the portio dura.

Supposing that the portion of the jaw between the angle and symphysis had been removed on account of osteosarcoma, and that the ramus subsequently became affected, it is no easy matter to effect disarticulation, as I have experienced.—The patient was a female, aged 30, of delicate constitution, and subject to toothache from infancy. I removed an osteosarcomatous tumour, extending from the angle to the canine tooth, on the right side. Division was made wide of the existing disease, and the sawn surfaces appeared quite healthy; but about five months afterwards, symptoms of return occurred in the ramus, and ten months after the first operation disarticulation was indispensable. The operation was accomplished with very considerable difficulty, on account of there being no lever to overcome the action of the temporal muscle. After separating the attachments as much as possible, an attempt was made to force down the coronoid process, from under the zygoma, by pushing the lower end of the bone backwards, in order to divide the insertion of the temporal muscle; but this proved ineffectual. The capsular ligament of the joint was then divided, and the bone with difficulty turned over from behind, forwards. It was then detached underneath the coronoid process, pulled down from under the zygoma, and the temporal muscle at length divided at its insertion.

In none of these operations is there a necessity for preliminary exposure and ligature of either the carotid artery or its branches; by so doing, a great addition is made to the patient’s sufferings, the real operation is only commenced when the patient supposes it should have been finished, and he is thus annoyed and worn out. The flow of blood is easily moderated, or altogether arrested, by the pressure of an assistant’s fingers against the forepart of the vertebræ, below the angle of the jaw.

The position of the patient is either recumbent, with the face turned from the operator, or sitting with the head supported and steadied.

The instruments required are, a very strong, sharp-pointed bistoury, for division of the soft parts; saws, of which Hey’s is to be preferred for notching the bone; strong and long pliers, for completing its section; an aneurism needle, for securing the common trunk of the temporal and internal maxillary artery; dissecting and artery forceps, hooks blunt and sharp, narrow copper spatulæ, ligatures, &c.

_Wounds of the Face and Neck._—Accidental wounds of the face may involve the more important blood vessels and nerves, and interfere with the eye or its appendages, with the nose, or with the mouth. Injury of these parts is to be avoided in incisions premeditated for the removal of disease or deformity; and, in such premeditated wounds, the line of incision should always be, if possible, in the direction of the muscular fibres. The bleeding seldom proves troublesome; pressure on the vessels, as they pass over the bones, arrests it temporarily; and ligature is seldom required, accurate adaptation of the divided surfaces proving sufficient for effecting permanent closure of the divided branches. Paralysis, more or less extensive, follows division of the nerves and muscles. But paralysis of the face also arises from a variety of other causes; it often remains after injuries of the head, probably in consequence of extravasation on the brain; it attends on morbid formations in the substance of the brain, or in its membranes, and follows long-continued irritation in the neighbourhood of the nerves. Paralysis from the last-mentioned causes is not likely to be recovered from; that following simple division of nerve, may disappear after a considerable time, the nervous tissue reuniting, and resuming its functions. When there is reason to suppose that the nervous function is alone deranged, while the structure remains sound and the continuity undissolved, advantage may follow the application of strychnine to a raw surface over the course of the affected nerves.

In Tic Doloureux, division of the nerves of the face, as they pass out of the foramina, is seldom resorted to; nor ought it to be practised, unless at the urgent request of the patient, and after all other means have failed to afford relief; and even then the operation is scarcely warrantable, since it may be said never to have succeeded in affording permanent relief. We must trust to milder measures, to the removal of local irritations, to paying strict attention to the digestive organs, to the administration of purgatives, tonics, and anodynes; occasionally benefit has resulted from the external use of the nitrate of silver, applied so as to cause very slight vesication. Ointments containing veratria and aconitine have been used with advantage, and the endermic application of the salts of morphia has also been found useful.

Spasmodic action of the muscles of the face, without pain, sometimes follows wounds and other injuries of the nerves which supply them; and sometimes no cause can be assigned for the occurrence. In this affection also, the application of nitrate of silver to the integuments over the nerves may sometimes be made with advantage.

Division of the parotid duct, or wound of the gland itself, is occasionally followed by the formation of a fistulous aperture, discharging saliva over the cheek. We endeavour to prevent this by accurate union of the recent wound. After the fistula has formed, an opening is to be made from it into the mouth, and kept pervious; the external aperture is then closed by suture after excision of the smooth edges, or is made to contract by the repeated application of a heated wire; pressure alone is of little use.

All wounds of the face are to be put into the most favourable state for healing without granulation, so that deformity may be prevented as much as possible. The twisted suture is best adapted for this purpose; more accurate coaptation being thereby obtained than by the interrupted form. In extensive wounds, the parts may be brought somewhat into their proper position by a few points of interrupted suture; twisted sutures are then placed in the intervals, and the isinglass plaster is of use in closing those points which may still gape slightly; in many cases, the greater part of the approximation may be accomplished by isinglass plaster alone.[38]

Deep wounds behind the angle of the jaw, and at the lateral and lower parts of the neck, are highly dangerous; indeed they are almost certainly and immediately fatal, as can readily be understood when the large bloodvessels and important nerves are considered which have their course in these parts, and which must be either wounded or completely divided. The bleeding has in some cases been arrested by immediate ligature of the divided extremities of the vessel, by firm and permanent pressure, or by pressure at first, and ligature of the trunk of the vessel on the recurrence of hemorrhage after the lapse of many days; of these methods immediate ligature of each extremity is certainly the safest and best. In lacerated wounds violent hemorrhage may take place some time after the infliction of the injury, from ulceration or sloughing of a large artery; in such circumstances either permanent pressure may be resorted to, or ligature applied to the vessel above and below the open point.

Dissections for the removal of morbid growths in the situations just mentioned must be conducted with much caution, and with a full recollection of the relative anatomy. Unless the tumour be tolerably loose and defined, it ought not to be interfered with. But it is to be recollected that tumours of these parts are bound down by their condensed coverings—the platysma myoides and cervical fasciæ; and that after division of these, the tumour, if not intimately incorporated with the neighbouring tissues, is loosened, and often enough can be readily detached.

From constant external pressure, tumours growing rapidly spread amongst the deep parts, and often form firm attachments. The parotid is displaced, and almost entirely absorbed, by the pressure of tumours growing out of the lymphatic glands which are lodged on its anterior surface. Such tumours attain a large size, and occupy the exact situation of the parotid; on their removal, the space betwixt the angle of the jaw and the mastoid process is completely exposed, and the styloid and pterygoid processes can be distinctly felt. From these circumstances many have been led to believe that they have dissected out the parotid; but this and the other salivary glands seldom if ever degenerate. And if the parotid do become the seat of carcinoma or medullary sarcoma, it is impossible to remove it with either safety or advantage. Even in the healthy state, removal of the parotid is a troublesome dissection; and the difficulty must be greatly increased when enlargement has taken place from disease, when neighbouring parts are involved, when firm and deep connections have been formed, and important structures encroached upon. I have taken away many tumours from the site of the parotid, and some of large size, but would scarcely attempt, or boast, as some have done, of having removed the diseased gland itself.

The incisions, for the removal of the tumours of which we have been speaking, are to be made in the direction of the fibres of those muscles which are interposed betwixt them and the integuments, in the direction of the bloodvessels and nerves, and towards those points where the vessels are expected to enter the diseased mass. Attention to the last recommendation is important in order to save blood. For when the trunks of the arteries are divided at the commencement of the dissection, they are easily secured temporarily by the fingers of an assistant: the operation is proceeded in and accomplished with scarcely any further hemorrhage, and in many instances no other vessels require ligature; whereas, if an opposite course be pursued, the same vessels will be divided three or four different times; the hemorrhage will be greater, and the operation delayed. By cutting also in the direction of the vessels and nerves, fewer arteries are divided, and nerves are less apt to be injured, than if the incisions were made across.

Wounds inflicted with the view of effecting suicide are generally on the fore and upper part of the neck, and their severity depends on the resolution of the individual. Some penetrate the integuments merely, and are consequently of slight extent; there is little bleeding, and the edges are easily brought together, after the cessation of bleeding and when the surfaces are glazed, by inclining the head forwards, and introducing a few points of suture. Others divide the muscles, and branches of the lingual or of the superior thyroid arteries; such wounds are gaping, more extensive than the former, and accompanied with smart hemorrhage. Some penetrate the mouth, separating the os hyoides, tongue, and epiglottis from the thyroid cartilage. Occasionally the wound is lower, through the thyroid, or betwixt that cartilage and the cricoid; and sometimes through these into the gullet; it is seldom lower. Such are truly horrible; the countenance is contorted, and presents a frightful expression; inspiration is difficult, hurried, and noisy, and at each expiration blood frothed with air is forcibly ejected from the wound. I have seen wounds of the trachea, near the top of the sternum, but without extensive division of the lateral parts; large wounds, such as are usually made at the upper part of the neck, could not be inflicted here without division of the large vessels, and instant death. Some determined suicides reach the vessels even high in the neck, dividing everything down to the vertebræ; immediate dissolution takes place from loss of blood. But, in general, mere opening of the air-passage is all that is aimed at, there being a vulgar notion that this is sufficient for the extinction of life. A considerable quantity of blood is lost, though the branches only of the external carotid are wounded, and the loss may prove fatal; but the hemorrhage generally ceases on syncope taking place; and if the patient be then discovered, means should be immediately adopted for permanently arresting it. Its recurrence may cause death, on the patient recovering from the first faint; or he may die some days after, from the effects of loss of blood. Hemorrhage, though to no very alarming extent, is always to be dreaded in those advanced in life; though in most cases the fatal result is not attributable solely to the bleeding, but is expedited by other circumstances, as defective supply of proper nourishment, and an unfavourable state of the mind.

Some patients seem to be going on most favourably towards a cure, but, within two days after the injury, are suddenly seized with difficult breathing, and die in a few minutes. On the examination of such, blood is sometimes found in the ramifications of the bronchial tubes, and the lungs can contain little or no air; or the bronchial tubes and ramifications are loaded with adherent mucus; in either case the patients die from asphyxia. In others, nothing remarkable is observed; perhaps passage of the air may have been prevented by inspissated mucus lodging in the windpipe around the wound, and closing the aperture, or by faulty adaptation of the divided surfaces. Likewise, during motion of the head, or attempts to swallow, either the upper or lower part of the windpipe may change its relative position; the continuity of the tube will be thereby destroyed, either partially or wholly, and suffocation ensue. When the wound is large and transverse, as the majority of such wounds are, there is difficulty in freeing the air-passage from mucus. This result becomes evident, when we consider how coughing is effected in the healthy state of parts—that the upper part of the windpipe is contracted by its own muscles, and the air driven through, by sudden action of the muscles of the chest, in a forcible and small stream, so as to carry the mucus along with it. This process cannot be accomplished when the muscles employed in contracting the orifice of the larynx are injured, or when an opening is formed below the glottis, through which the patient breathes, either wholly or in part.

In other cases, death is more slow. The patient is seized with dyspnœa, great anxiety, and occasional spasmodic action of the muscles of respiration, which symptoms gradually become more urgent and alarming. They are attributable to awkward position of the parts, to swelling around the wound, inflammatory or œdematous and rapid or slow, or to bronchitis. To the latter affection patients breathing through artificial openings in the larynx or trachea are peculiarly subject, probably from the inspired air not being heated, as in natural respiration, before it enters the bronchial tubes. A view from behind is here introduced of the larynx of a patient who some weeks previously attempted suicide by wounding the forepart of the neck. By some mismanagement the edges of the incision were kept asunder, and they cicatrised. The patient was seized with difficult breathing, the inspirations were rare, long, and laborious; he had threatening of suffocation during his disturbed sleep. These symptoms were disregarded. He started up suddenly in the night, caught hold of the patient in the next bed, and fell down in a state of asphyxia, from which he could not be recovered. The œdematous swelling of the rima glottidis is remarkable; beyond that is seen the rounded opening betwixt the thyroid cartilage and epiglottis, which is in a normal state.

The bleeding is to be arrested as speedily as possible by ligature, and the patient placed in bed with the head and shoulders raised. The edges of the wound are brought together by attention to the position of the head; but, provided the patient breathes easily with the wound open, closure should not be attempted till after eight, ten, or twelve hours—that is, not until all oozing of blood has ceased; the time depends on the extent to which the air-tube has been divided. There is little chance of immediate union taking place; and the wound not being approximated when recent and bleeding, does not diminish the chance, but on the contrary augments it. Adhesion is prevented by the insinuation of air and mucus betwixt the edges, by frequent motion of the edges on each other, by the slightest change in the position of the head, either rotatory or nodding, by the action of the muscles of the os hyoides, and by attempting to swallow food or saliva. Every circumstance is opposed to complete approximation and immediate union of transverse wounds of the throat.
