The physi cian advised hot applications externally but th e swelli ng spread. An x -ra y showed a honey-comb . condit ion of th e bon e ( F ig . 1).

Th e floor of th e mouth was also s wollen with ver y little redness. Th e patient could open a nd close the mouth easily . February 24, 1926, th e pati ent was admitted to th e hospital with a temperature of 101. (1° F . an d blood count of 2,760,000 red cells and 6,450 whit es. Th e next day, und er gas and et her anest hesia, th e sof t tissues a ll the buccal sid e were stripped off to a ffor d better dra in ag e and a ll deciduous teeth anteri orly to llril were removed . Th e bone was necrotic but not sequestrated. Dressings wer e changed a t intervals of for ty-eight hours and two weeks later t he patient left the hospital. Two weeks a f te r her discharge from the hospital, the patient presented herself with a swelling and tenderness in the left mandibular region. Blood count showed 4,100,000 red cells a nd 20,800 whites. Patient was r eadmitted to the hospital on March 26, 1926, when an external incision was made at the angle of the left side of the mand ible. Nine days later a large sequestrum was removed. At intervals of a few days, sever al small sequestra wer e removed f r om the left side of the mandible and about ten days later th e right side of the face became swollen and the patient was ag a in placed in the hospit al. An ex te;'na l incision was made under ga s and ether ane sthes ia ( Apr il 28, 1926) , at th e r igh t mandibular angle an d a. large amount of pus drained , The submaxillary a nd superi or cer vica l gla nds wer e f ound to he involved and t hese were drained.

F'ree drainage and watchful waiting arc indicated. Wherever pus is found, a surgical incision is made; whenever bone is separating as a sequestrum, it is removed. Occasionally an osteomyelitis is produced by an early incision and curettage in case of an acute periostitis, which without surgical interference would most likely have disappeared in due time. Curettage of painful and of so-

called dry sockets is frequently followed by infection of the surrounding bone, ending in the formation of sequestra. Many teeth can be saved during the treatment, especially permanent ones even though not fully developed. Assuming the responsible tooth has been removed, one should not hurriedly sacrifice all loose teeth-as most of them

will be dur-ing the acute ~taw~-but rather wait for the subsidence of the acute symptoms, after which quite a few will become firm and continue to develop to become useful members of a damaged masticating apparatus. When the condyle and neck of the ascending ramus have been sequestrated in growing' patients, shortening of the afIected side can be largely prevented by continuous and faithful exercise. This consists of opening and closing the jaws either straight up and down or preferably somewhat toward the sound side and also keeping the closed jaws in proper (normal) occlusion, This exercise performed three times daily sufficiently stimulates the parts to new bone formation and restores fairly normal function.

POLLICULAR CYSTS CAS~] 2.-~'0Ilicular
cyst (originating from :3 I).
M. G., male, aged 3:3 years, November,
1918.
Chief Co-mplaint.-For the past ten or fifteen years the patient has had a slight swelling in the mouth, but no pain. Recently some teeth were extracted and a few days ago the mandible eommenced to swell. The patient also complained of considerable pain, which was also quite recent. The profile had the appearance of prognathism, although the bite was normal, due to the extension and distension of the outer cyst wall (Fig. 3). There was
i

fluctuating swelling from (; to 1'5 inclusive and was missing. Upon aspirating and then incising, a large amount of cyst fluid containing cholesterin crystuls, polynuclear leucoeytes and fat globules was washed out. Blood and urine negative.

Radicular and follicular cysts are treated either radically or conservatively. Only in the larger cysts-particularly the ones adjoining the antrum or nasal chambers-the conservative treatment is employed, namely, the removal of the outer plate of bone and cyst wall, leaving th'e i~ner cyst wall in position; in other words, transforming the cyst cavity into a shallow accessory cavity of the mouth.

A considerable number of follicular cysts develop from malposed mandibular canines. In these cases most of the teeth in the region of the cyst have remained vital and therefore can be saved (Fig. 13). If the apices extend into the cyst cavity or are likely to be injured at the time of the operation, their root canals should be filled before and their apices amputated at the time of the operation (seE' I<~ig. 9).

'I'he incision was continued Imguully, but not cnu nected posteriorly. .Iust posterior to the mental foramen, the mandible was divided with a Gigli saw, but the posterior part of the tumor had to be chiseled out en musse.

l'heodol' Blum While the treatment of malignant tumors must necessarily be radical, still a certain group of cases call be taken care of, apparently successfully, without disfigurement or loss of function. More can be accomplished by radium and x-ray followed by operation than any other method known to the author. Carcinomas of the mucous side of the cheek, the floor of the mouth,

others beginning at the mucous membrane covering the alveolar ridge and involving the bone, etc., have remained without recurrence for at least four years, and-nota bene-without having' undergone operations, the results of which would have kept the patient secluded on account of the disfigurement and made him miserable on account of loss of function.

This treatment of ma.lignancies of the oral cavity, consisting of radium and x-ray followed by operation, is of course not always successful, but certainly more so than any other method. The case of epidermoid carcinoma reported was pathologically not a very malignant one and was operated on first and then treated with radium and x-ray as was thought best at that time. Fortunately, up to date no recurrence has been noted (Fig. 25). This discussion of diseases of the jaws is based on actual cases treated and should therefore accentuate the importance of the remarks made in their connection. The main reason or excuse for reporting' them is to preach and spread the gospel of couservatism. Good surgery is not radical. DI8UUSSION
Dr . .Armil~ Wald, New Yorl: City, N. Y.-It was indeed a great pleasure to heal' and see :111 that Dr. Blum so ably presented to us this eyening and there is little that I cun say, except in praise of his work und to ask you to think seriously 011 the point he atresses, namely that of good surgery. When the essayist speaks of radical and conservative surgery and their relative merits, he really has in mind goo(l smgery. When radical methods are imperative, he too is the advocate of them, and when conservative methods are indicated, the essayist, as we all, I am sure, would operate to conserve anrl restore, In malignancy, radical operations in and about the mouth arc beyond the field uf tl.« average oral surgeon and when these conditions progress to that stage where radical removal of all possibly infected tissue is imperative, I am sure that Dr. Blum will agree that it would be poor surgery to be conservative, On the other hand, to interfere in this manner il~ treating an osteomyelitis, that is, to remove radically all tissue that might possibly become infected would certainly end disastrously and be poor surgel'Y. It is not surgel'y at all that leads the tyro to curette the dry socket, or to abuse the case of acute periost it is as described by Dr. Blum, and I doubt if anyone here present would advocate such procedure. "Fools rush in where angels fear tu tread." The importance of conservation of tissues of the mouth and the restoration of diseased tissues is the constant problem of the dentist am] the oral surgeon.
