[Intracranial penetration of the mandibular condyle: report on three cases (author's transl)]. / Pénétration intracrânienne du condyle mandibulaire. A propos de trois cas.

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.

[The dangers of Trauner's operation]. / Les écueils de l'opération de Trauner.

The technique described by Trauner for using retro-condylar cartilaginous implants is outlined, and the complications observed indicated. External or inferior luxation of the implant leads to recurrence of the deformity, whereas no inconvenience is caused by the opening of the joint. These pitfalls led to the use of a modified technique in which the cartilaginous implant is introduced into the supra-meniscal cavity of the temporo-mandibular joint.

[One-stage surgical treatment of temporo-mandibular ankylosis and its facial deformity]. / Traitement chirurgical en un temps d'une ankylose temporo-mandibulaire et de sa déformation faciale.

A patient with temporomandibular ankylosis was treated by resection of the ankylosed block followed by lengthening of the ascending ramus by an endoprosthesis. The place of the latter in the treatment of such lesions and the deformities that result from them is analyzed. Emphasis is laid on the value of displacement of the superior arch by a Le Fort I osteotomy in the correction of facial asymmetry in cases of laterognathia due to a mandibular development defect.

[An osteo-cartilaginous graft for ankylosis]. / A propos d'une greffe ostéo-cartilagineuse pour ankylose.

Ankylosis of the temporomandibular joint was treated by resection of the ankylosed block and arthroplasty with an osteo-cartilage graft from the rib. The main feature was attaching the cartilage to the bony surface and the appearance of enchondral ossification. The value of this method is discussed.

[Post-operative developments after resection of the mandibular body or angle for mandibular protrusion]. / Etude de l'évolution post-opératoire après résection du corps ou de l'angle pour promandibulie.

Teleradiographic examinations were conducted pre- and postoperatively and one year after resection of the body (5 cases) or angle (10 cases) of the mandible for mandibular protrusion in 15 patients. Clinical results of these operations appeared to be very stable, but teleradiographic modifications were observed constantly after one year. Resection of the body has little effect on the position of the ascending rami, whereas angle resection usually results in parasitic movements in this region, their pre-operative condition being re-established in practically all cases. Following shortening of the body there is an almost constant drop in the symphysial region. These movements appear to arise from activity of masticatory and suprahyoid muscles, with an accessory role being played by the tongue.

[Primary lymphoma of the sublingual gland. A case report (author's transl)]. / Lymphome primitif de la glande sublinguale. A propos d'un cas.

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.

[The role of condylectomy in the treatment of mandibular laterognathism in children]. / Place de la condylectomie dans le traitement des latérognathies mandibulaires de l'enfant.

In 7 cases of mandibular laterognathia caused by condylar hypertrophy, the authors specify the clinical and teleradiological features in adolescents. They emphasize the inadequacy of lateral teleradiography and of its measurements, and the need for three-dimensional investigation. In adolescents, secondary deformations, either spontaneous or therapeutic, are rare, and the treatment preferred is condylectomy based on the study of casts. The immediate results of this techniques are satisfactory. The long-term consequences on growth and temporomandibular pathology have been studied.

[Arteriovenous fistulas. Apropos of 2 observations]. / Fistules artério-veineuses. A propos de deux 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.
