[Conservative surgical treatment for large maxillary cysts. Some comments on technique (author's transl)].

Conservative surgical treatment for large maxillary cysts consists of releasing the cystic wall of the bony cavity without destroying the pulp of the teeth which have apices close to the operated cavity (unless the tooth is already dead). The vestibular approach is through one or two orifices and is as small in size as possible. This technique generally allows conservation of the vitality of the largest number of teeth and avoids postoperative collapse.

[Micrographic aspect of mandibular osteoradionecrosis (author's transl)].

Fragments of the lower jaw from 42 patients with carcinoma of the oral cavity or oropharynx, and treated primarely with fraction radiotherapy, were excised for radiation osteonecrosis 6 month to 10 years after irradiations. The excised specimens are X-rayed before being coated with methylmetacrylate. They are then cut into thick sections along lines detailled on the X-ray films. The sections are trimmed to 80 microns and examined microradiographically. Two observations are sufficient to demonstrate destruction or reorganisation of the bone tissue. Reabsorption of unusual appearance is seen around the Haversian canals. The newly formed tissue resembles either embryonic bone matter, or lamellar tissue as seen in osteomyelitis.

[Bone reconstruction after resection of the mandible for osteoradionecrosis (author's transl)].

Resection of the sections of the mandibular affected by osteoradionecrosis has completely modified the progression and prognosis of this affection by ensuring that the patient does not have to suffer long periods of pain and suppuration, constantly observed when medical treatment is used alone. Unfortunately, these resections are usually extensive and are themselves responsible for functional and esthetic sequelae supported with difficulty by some patients, especially in the case of bilateral or mandibular arch resections. All efforts must be made, therefore, to limit the consequences, and with this in mind it is possible: -- to perform an uninterrupted resection limited to the alveolar area involved, in early cases of mandibular osteoradionecrosis; -- to reconstitute mandibular continuity with a bone graft in more advanced stages; -- to improve the esthetic appearance with skin and subcutaneous grafts whenever this is necessary. Good results can only be obtained if certain anatomical conditions exist and if surgical precautions are adapted to each case.

[Diagnostic problems posed by acute necrosis of the extremities after electrocoagulation of an epithelioma of the floor of the mouth].

Three weeks after electrocoagulation of an enormous epithelioma of the floor of the mouth, a 62-year-old man presented after a shower-bath with symmetrical cyanosis of the toes and fingers with painful oedema coloured by livedo reticularis of the lower third of the legs and forearms. In the hands this developed into a dry necrosis and necessitated their amputation. In the absence of biological tests and a posteriori the authors discuss the diagnosis of cryoglobulinaemia and intravascular disseminated coagulopathy; but in fact, these two syndromes produce very similar cutaneous symptoms, notably, cryofibrinogenaemias, cryofibrinogen being a degradation product of fibrin liberated in C. I. V. D.

[Extrusion into the inferior dental canal of filling material. Apropos of 18 cases].

The purpose of this article is to draw the reader's attention to a fairly frequent complication in root treatments with suspicious clinical symptoms and in which painful complications are particularly to be feared. This complication appears therefore to be a stomatological emergency, treatment for which is aimed at bringing about regeneration of the traumatised nerve, prognosis being dependent on prompt surgical measures, the site of the complication and the anatomical damage done to the lower dental nerve.

[Facial manifestations of suppurative trichophytosis].

Several cases of facial suppurative Trichophytia described by the authors lead to a review of the clinical, mycological and pathological features of this disorder which is on the increase in the region of Nantes.
