Bilateral Posterior Dislocation of Mandibular Condyle: A Rare Entity in Maxillofacial Injuries

ConclusionThis is the first ever case report that highlights bilateral posterior dislocation of intact mandible unlike the previous four reports which have brought forth unilateral dislocation on English literature search. Posterior dislocation of mandibular condyle is encountered in edentulous patients who experience posteriorly directed impact which forces the condylar head behind the postarticular ridge. Unlike anterior dislocation, clinical features include reduced mouth opening and retruded mandible in bilateral dislocation. It has been observed that manual correction by pressing the mandible downwards and forwards yields good results in early cases. Cases that are reported late require surgical exploration for reduction and placement of anchorage ligament to prevent recurrence in unstable condyle.
