Reconstruction de l'articulation temporo-mandibulaire par prothèse totale intermédiaire

: A method for reconstruction of temporomandibular joint is proposed using an intermediary prosthesis and non-sealed cupula. This prosthesis respects the cranial articular slope and provides twofold mobility at the cupular level, which approaches physiological conditions and allows reproduction of buccal opening and closing movements as well as lateralization. A strict surgical procedure is essential when inserting the prosthesis, particular care being necessary in the approach to the facial nerve and control of its temporofacial contingent until above the zygomatic arch. Indications for this procedure are discussed in relation to injuries and tumoral, degenerative and malformatory lesions.
