CHAPTER VIII.

OPERATIONS ON MOUTH AND THROAT.

SALIVARY FISTULA, _Operation for._--After a wound or abscess of the

cheek, in which the parotid duct is implicated, a salivary fistula is

very apt to remain. The saliva thus discharges in the cheek, giving rise

to considerable annoyance, as well as injury to the digestion. It is by

no means easy to cure this. Perhaps the best operation is the one of

which a rude diagram is given (Fig. XXVIII.). The duct (C) communicates

with the fistula (D). One end of a thread, either silken or metallic,

should be passed through the fistula, and then as far backwards as

convenient through the cheek into the mouth; the needle should then be

withdrawn, the thread being left in. The other end being threaded should

then be re-inserted at the fistula, and carried forwards in a similar

manner; the needle should be again unthreaded in the mouth and

withdrawn; the two ends should then be tied pretty tightly inside, and

allowed to make their way by ulceration into the cavity of the mouth. A

passage will thus be obtained for the saliva into the mouth, and every

possible precaution should be taken to enable the external wound to

close.

EXCISION OF THE TONGUE, for malignant disease of the organ, may be

either complete or partial. Complete excision affords a hope of

permanent and complete relief from the disease, but it is an operation

of extreme difficulty and danger. It may be performed in either of the

following methods. The first is the only one in which absolute

completeness of removal is insured.

1. _Syme's method of excision._--The patient being seated on a chair,

chloroform was not administered, so that the blood might escape

forwards, and not pass into the pharynx. The operation is thus

described:[115]--

"Having extracted one of the front incisors, I cut through the middle of

the lip and continued the incision down to the os hyoides, then sawed

through the jaw in the same line, and insinuating my finger under the

tongue as a guide to the knife, divided the mucous lining of the mouth,

together with the attachment of the genio-hyoglossi. While the two

halves of the bone were held apart, I dissected backwards, and cut

through the hyoglossi, along with the mucous membrane covering them, so

as to allow the tongue to be pulled forward, and bring into view the

situation of the lingual arteries, which were cut and tied, first on one

side, and then on the other. The process might now have been at once

completed, had I not feared that the epiglottis might be implicated in

the disease, which extended beyond the reach of my finger, and thus

suffer injury from the knife if used without a guide. I therefore cut

away about two-thirds of the tongue, and then being able to reach the os

hyoides with my finger, retained it there while the remaining

attachments were divided by the knife in my other hand close to the

bone. Some small arterial branches having been tied, the edges of the

wound were brought together and retained by silver sutures, except at

the lowest part, where the ligatures were allowed to maintain a drain

for the discharge of fluids from the cavity." The patient was able to

swallow from a drinking-cup with a spout on the day following the

operation, and was able to travel upwards of 200 miles within four weeks

of the operation.

2. _By the Écraseur._--Nunneley of Leeds has recorded cases in which he

made a small incision through the skin, and mylohyoid and geniohyoid

muscles, and through this passed a curved needle bearing the chain of

the écraseur completely round the base of the tongue. In one case the

chain was unsatisfactory, but strong whipcord was introduced as it was

withdrawn, and tied with all possible force. The organ eventually

sloughed away, with a cure which lasted at least for some months.

Sir James Paget operates as follows:--

The patient is placed under the influence of chloroform, and the mouth

held widely open. The tongue is then drawn forwards, the mucous membrane

and soft parts of the floor of the mouth, including the attachment of

the genio-hyoglossi to the symphysis being divided close to the bone.

The steel wire of an écraseur is then passed round its root as low down

as possible, slowly tightened, and the tongue thus divided through its

whole thickness in a very few minutes. The bleeding is slight, being

almost entirely from the parts cut with the knife. Recovery has been

rapid in the recorded cases.[116]

To Dr. George Buchanan of Glasgow the credit is due of the invention of

the operation of removal of the half of the tongue in the median line.

In at least one instance the cure after five years is still permanent.

Partial excisions of the tongue are as unsatisfactory in their results

as they are unsound in principle, yet many cases present themselves, in

which, while the patient urges some operative measure for his relief,

the tumour is so limited as not to warrant the exceedingly dangerous

operation of complete excision.

Portions may be removed in various ways:--

1. By the knife. If in the apex, by a V-shaped incision; if in the

lateral regions, by a bold free incision with a probe-pointed bistoury

round the tumour.

2. By ligature, drawn as tightly as possible, and, if the portion

included be large, in successive portions.

3. By the écraseur.

Mr. Furneaux Jordan has removed the whole tongue with success by means

of two écraseurs worked at the same time.[117]

4. By the galvano-caustic wire.

5. The author has in nine cases removed the affected half of the tongue

by means of the thermo-cautery, first splitting it in the middle line

and then cutting through the base with a curved platinum knife at a low

red heat. In one only was there any trouble from hæmorrhage, and all

made good recoveries.

Mr. Barwell has recorded (_Lancet_, 1879, vol. i.) an easy, safe, and

comparatively painless mode of removing the tongue by écraseurs.

Mr. Walter Whitehead,[118] of Manchester, has had a very large

experience of an operation devised by himself, in which, after pulling

the tongue well forward by a string previously introduced near its apex,

and the mouth being held open by a gag, he detaches the organ from jaw

and fauces by successive short snips with scissors, and then in same

manner divides the muscles, tying or twisting the vessels as they bleed.

His success has been very great by this method, though others who have

tried it have sometimes found bleeding troublesome.

It is comparatively seldom now necessary to split the jaw and perform

Syme's operation, and in all operations on the tongue the thermocautory

(Paquelin's) is of great use.

Regnoli's method[119] may deserve a brief notice. A semilunar incision

along the base of the jaw, from one angle to the other, detaches the

muscles and soft structures, and is thrown down; the tongue is then

drawn through the opening, and can be freely dealt with either by knife

or ligature. After removal the flap is replaced.

FISSURES IN THE PALATE.--The operations requisite for the cure of

fissures in the soft and hard palates are so complicated in their

details, that a small treatise would be required thoroughly to describe

the various procedures.

Different cases vary so much in the nature and amount of their

deformity, that at least five different sets of cases have been

described. It is sufficient here merely to describe the absolutely

essential principles of the operations for the cure of fissures of the

hard and soft palate respectively.

In all operations on the palate, two conditions used to be considered

requisite for success:--1. That the patient should have arrived at years

of discretion, at twelve or fourteen years at least; that he be

possessed of considerable firmness, and be extremely anxious for a cure,

so as to give full and intelligent co-operation. 2. That for some days

or weeks prior to the operation the mouth and palate should have been

trained to open widely and to bear manipulation, without reflex action

being excited. Professor Billroth of Vienna,[120] and Mr. Thomas

Smith[121] of London, have had cases which prove the possibility of

performing this operation in childhood, under chloroform, with the

assistance, in the English cases, of a suitable gag, invented by Mr.

Smith. The effect of the operation on the voice of the child has been

very encouraging, as much more improvement takes place than in cases

where the operation is performed late in life.

_Fissure in the soft palate only_ appears as a triangular cleft, the

apex of which is above, the base being a line between the points of the

bifid uvula, which are widely separated. To cure this it is required--

1. That the edges of the fissure should be brought together without

strain or tightness. In small fissures this can generally be done easily

enough; but where the fissure is extensive, some means must be used to

relieve tension. For this, Sir William Fergusson long ago proposed the

division of the palatal muscles, the levator, tensor, and

palato-pharyngeus muscle of each side. The incisions in the palate for

this purpose certainly aid apposition, but many surgeons entertain

doubts whether the division of the muscles has much to do with the good

result, and believe that the simple incisions in the mucous membrane, in

a proper direction, are all that is required (see Fig. XXIX.).

[Illustration: FIG. XXIX.[122]]

2. That the edges of the fissure be made raw, so as to afford surfaces

which will readily unite. Complicated instruments, such as knives of

various strange shapes, have been devised for this purpose; an ordinary

cataract knife, very sharp, and set on a long handle is perhaps the

best. It greatly facilitates the section if the parts are tense, so the

point of the uvula should be seized by an ordinary pair of spring

forceps, and drawn across the roof of the mouth, while the knife should

enter in the middle line, a little above the apex of the fissure, and

make the cut downwards as in harelip.

3. That sutures should be inserted to keep the edges in apposition, yet

not so tightly as to cause ulceration. They may be either of metal,

silver being preferable, or of fine silk well waxed. The metallic

sutures are now generally preferred. Some dexterity is required in their

introduction, and various instruments have been devised; the best seems

to be a needle with a short curve fixed on a long handle, which should

be entered on the (patient's) left side of the fissure in front, and

brought out on the right side.

If silk sutures be used, the chief difficulty, that of passing the

thread through the second side from behind forwards, can be avoided in

the following manner.[123] A curved needle is passed through one side of

the fissure, and then towards the middle line, till its point is seen

through the cleft. One of the ends of the thread is then seized by a

long pair of forceps, and drawn through the cleft; the needle is then

withdrawn, leaving the thread through the palate, and both ends are

brought outside at the angle of the mouth. Another needle is then passed

through a corresponding point at the opposite side of the palate, till

its point again appears at the cleft; this time a double loop of the

thread is also brought out through the cleft by the forceps into the

mouth. If then the single thread of the first ligature which is in the

cleft be passed through the loop of the second one also in the cleft, it

is easy, by withdrawing the loop through the palate, to finish the

stitch (see Fig. XXIX.). All the stitches should be passed and their

position approved before any one be tied, and it is most convenient to

secure them from above downwards. To prevent confusion, each pair of

threads after being inserted should be left very long, and brought up

to a coronet fixed on the brow, which is fitted with several pairs of

hooks numbered for easy reference. This will prevent twisting of the

threads or any mistake in tying.

FISSURE OF THE HARD PALATE.--This may vary in extent from a very slight

cleft in the middle line behind, up to a complete separation of the two

halves of the jaw, including even the alveolar process in front, and

sometimes complicated with harelip.

To close such fissures by operation is difficult, as the breadth of the

cleft is so great as to prevent the apposition of the edges when

prepared, without such extreme tension as quite prevents any hope of

union. Through the researches of Avery, Warren, Langenbeck, and others,

a method has been discovered of closing such fissures by operation,

which, though certainly not easy, is, when properly performed, generally

successful.

_Operation._--In addition to the usual paring of the edges of the cleft,

an incision is made on each side of the palate, extending "from the

canine tooth in front to the last molar behind,"[124] along the alveolar

ridge (Fig. XXX.). The whole flap between the cleft and this incision on

each side is then to be raised from the bone by a blunt rounded

instrument slightly curved. With this the whole mucous membrane and as

much of the periosteum as possible should be completely raised from the

bone, attachments for nourishment of the flap being left in front and

behind where the vessels enter.

[Illustration: FIG. XXX.[125]]

The flaps thus raised will be found to come together in the middle line,

sometimes even to overlap, and, when united by suture, form a new

palate at a lower level than the fissure, experience having shown that

in cases of fissure the arch of the palate is always much higher than

usual. The flaps do not slough, being well supplied with blood, unless

they have been injured in their separation.

The edges must be carefully united by various points of metallic suture,

and the fissure of the soft palate closed at the same sitting, unless

the patient has lost much blood, or is very much exhausted with the

pain. The stitches may be left in for a week, or even ten days, unless

they are exciting much irritation. The patient must exercise great

self-control and caution in the character of his food and his manner of

eating for ten days or a fortnight after the operation.

EXCISION OF TONSILS.--To remove the whole tonsil is of course impossible

in the living body, the operation to which the name of excision is given

being only the shaving off of a redundant and projecting portion. When

properly performed it is a very safe, and in adults a very easy

operation, but in children it is sometimes rendered exceedingly

difficult by their struggles, combined with the movements of the tongue

and the insufficient access through the small mouth. Many instruments

have been devised for the purpose of at once transfixing and excising

the projecting portion; some of them are very ingenious and complicated.

By far the best and safest method of removing the redundant portion is

to seize it with a volsellum, and then cut it off by a single stroke of

a probe-pointed curved bistoury; cutting from above downwards, and being

careful to cut parallel with the great vessels.

The ordinary volsellum is much improved for this purpose by the addition

of a third hook in each tonsil placed between the others, with a shorter

curve, and slightly shorter; this ensures the safe holding of the

fragment removed, and prevents the risk of its falling down the throat

of the patient.

If both tonsils are enlarged they should both be operated on at the same

sitting, and the pain is so slight that even children frequently make

little objection to the second operation. Bleeding is rarely troublesome

if the portion be at once fairly removed, but if in the patient's

struggles the hook should slip before the cut is complete, the partially

detached portion will irritate the fauces, cause coughing and attempts

to vomit, and sometimes a troublesome hæmorrhage.

The plentiful use of cold water will generally be sufficient to stop the

bleeding, though cases are on record in which the use of styptics, or

even the temporary closure of a bleeding point by pressure, has been

necessary.

M. Guersant has operated on more than one thousand children, with only

three cases of any trouble from hæmorrhage, while four or five out of

fifteen adults required either the actual cautery or the sesqui-chloride

of iron.[126]
