[Condylar remodelling after temporomandibular joint reconstruction with fibula free flap].

AIM: Mandibular reconstructions with fibula free flap are commonly used in maxillo-facial surgery; termino-lateral mandibulectomy with reconstruction of the ramus and condylar unit is seldom used. Consequences on the temporomandibular joint remain unclear, and the type of reconstruction is still subject to controversy.

METHODS: Six patients were followed after terminal mandibulectomy, reconstructed with fibular free flap. Evaluations of the results were made on functional and radiological criteria.

RESULTS: No patient presented functional disturbances due to reconstruction. Remodeling of the neocondyle extremity was weak in adults but important in children, with modification of morphology and architecture of the condyle in children.

DISCUSSION: Preservation of the disc is recommended. Many techniques are described to improve congruence, preservation and remodeling of the free extremity of the fibula flap. All give similar results. It seems that the real determinant factors on the quality of the result are age, presence of the disc or not, previous surgery performed, with or without radiotherapy.
