[Arteriovenous fistulas. Apropos of 2 observations].

Two cases of mandibular angiodysplasia associated with hemorrhagic phenomena were treated surgically, by conservation resection in one patient and conservative surgery following embolization in the other. External carotid artery ligature is a useless and even risky procedure, whereas surgery should be preceded by tumoral embolization whenever possible. Prognosis, according to the classification proposed by Merland, depends upon whether active vascular malformations, mainly represented by arteriovenous fistulae, are present, or whether the lesions are inactive vascular malformations or with slowed circulation.

[Primary lymphoma of the sublingual gland. A case report (author's transl)].

Primitive malignant lymphomas involving salivary glands are rarely observed. Among the cases, the parotid gland is more often affected than the submandibular. A case of sublingual gland lymphosarcoma is reported here with clinical-pathological "staging" established according to Ann arbor classification extended to non Hodgkin's lymphomas (stage I). Histological data suggest a case of "Diffuse Histiocytic "lymphoma" (D. H. L.) in Rappaport's Classification. Treatment regimen was chosen in conformity with current concepts; that is simple excision of the sublingual gland, followed; that is simple excision of the sublingual gland, followed by radiation therapy and chemotherapy (C.V.P.). After one year, the patient is still free of relapse. However, at the present time no definite prognosis can be ventured.

[Intracranial penetration of the mandibular condyle: report on three cases (author's transl)].

Three cases of intracranial penetrations of the mandibular condyle condyle are reported, the published literature reviewed, and therapy discussed. Often unrecognized during initial examinations, they are diagnosed when the patient is seen several months later with permanent constriction of the jaws. Frontal and sagittal tomographic examinations should therefore be performed in the articular region in all cases when it is involved in injuries. Orthopedic reduction gives good results in recent injuries, long-standing cases with temporomandibular ankylosis requiring sub-condylar resection by the pre-auricular approach.

[Recent advances in the therapy of osteoradionecrosis of the maxillomandibular bones (author's transl)].

In spite of the considerable technical progress made over the last few years, no type of irradiation used at the present time for treating malignant tumors in the maxillofacial region can protect the patient from the always dreaded appearance of a secondary osteoradionecrosis of the maxillomandibular bones. Extablished osteoradionecrosis is not a "true" necrosis of these bones but a particularly severe osteitis which evolves in bone, which is pathological because it has been irradiated, and is surrounded by tissues which are also pathological for the same reason. Very high doses of antibiotics, comparable to those used in the treatment of osteomyelitis, mandibular resection by the endobuccal route, and the possibility of treating perimaxillomandibular tissues by reconstructive surgery, have completely transformed the prognosis of this dreaded affection, which is being increasingly prevented by daily fluoride applications applied locally.

[Resection of the mandibular angles in the treatment of prognathism].

The technique involves transposition at the site of the angle of resection via an intrabuccal approach of the horizontal ramus at its various stages. The technique is dependable and is indicated whenever correction of the malformation requires mass displacement of the dental arcade. It is preferable to sagittal split of the ascending ramus since it is more precise and less dangerous as far as the neurovascular bundle is concerned.
