Bilateral bifid mandibular condyle with temporomandibular joint ankylosis: A rare entity

Abstract

Bifid mandibular condyle (BMC) is an uncommon condition with only few cases reported in the literature. Bilateral BMC is even more rare with an incidence one eighth that of unilateral BMC. Etiology of BMC is controversial, but two most common factors implicated include anomalous development and previous trauma. Association of BMC with temporomandibular joint (TMJ) ankylosis is exceptionally rare. We here report a case of bilateral bifid mandibular condyle with TMJ ankylosis in a 22 year old female with history of facial trauma six year prior to presentation.
