Epithelial inclusion cyst in the temporomandibular joint after a dermal graft.

Abstract

Perforation of the temporomandibular joint (TMJ) disc presents a perplexing problem when encountered during surgery. When it occurs, there is direct contact between the mandibular condyle and the articular eminence of the temporal bone during functional movements. This bone-to-bone contact may lead to pain, limitation of movement and osseous changes. Small perforations can sometimes be repaired primarily if they are in the periphery of the disc. Discectomy has also been advocated.1 However, several authors have demonstrated the adverse effects of complete disc removal.2–4 The use of dermal grafts in the repair of the TMJ disc has also been advocated by several authors.5–7 This paper presents one complication from the use of an autologous dermal graft to replace the TMJ disc.
