[Tumors of the mandibular condyle (author's transl)].

Three cases of tumors of the mandibular condyle are reported. One patient had metastases from a cutaneous melanoblastoma, another a benign osteochondroma, and the third a plasmocytosarcoma revealing the presence of Kahler disease. The authors emphasize the rare nature of these lesions, in spite of the technical advances made in the radiological and surgical exploration of the temporomandibular joint, and also the large variety of histological types reported in the literature.

[Maxillodental problems after irradiation in children (author's transl)].

The treatment of a certain number of children with very severe dentomaxillary sequelae after radiotherapy for facial and intracranial lesions raises many problems. These include the type of reconstructive therapy, the protection of the maxillodental structures, the value of local and alimentary hygiene, and the quantity and quality of dental treatment needed. Further difficulties are encountered because of dental malformations (absence of roots), increased rate of eruption of the teeth in the arch (contrary to the accepted opinions), and objectives should be modest when attempting maxillofacial orthopedic procedures.
