[Mandibular metastasis revealing thyroid carcinoma. Two cases]. / Métastase mandibulaire révélatrice d'un cancer de la thyroïde.

Although thyroid cancer is not the first cause of bone metastases, this diagnosis must be always entertained because when it is found to be the cause of the metastasis, the survival is good. Bone metastases can take on different appearances and thyroid cancer discovered secondarily. We report two cases of mandibular metastases revealing a thyroid cancer and we stress on diagnosis and therapeutic difficulties.

[The oculomotor effects of the fractures of the floor of the orbit]. / Les séquelles oculomotrices des fractures du plancher de l'orbite.

PURPOSE: Fractures of the orbit floor have very disabling oculomotor after effects. The objective of this study was to report that close collaboration between the maxillo-facial specialist and ophthalmologist is necessary to avoid oculomotor after effects. METHODS AND PATIENTS: Our study included 10 cases of the fracture of the orbit floor. These cases were recorded between 1992 and 1996. RESULTS: This pathology affected young subjects aged between 20 and 40 years in 70 % of the cases. 80 % of the subjects were males. 90 % of the patients presented a vertical diplopia as a result of a transitory oculomotor deficit. 20 % of the subjects presented a permanent oculomotor deficit at the stage of after effects. All these deficits were of a mechanical origin and, contrary to other authors, we found no deficit with nervous sensory origin. CONCLUSION: Therapeutic success is based on early diagnosis and treatment that requires close collaboration between the maxillo-facial and ophthalmology teams.
