title: Bilateral bifid mandibular condyle: a case report.
abstract: Bilateral bifid mandibular condyle is a rarely seen malformation. The aetiology of bifid condyle is not completely understood, although developmental anomaly, traumas, condylar fracture, teratogenic embryopathy and surgical condylectomy may all be causative factors. Although a few studies on human dried skulls tried to shed light on this entity it remains obscure. As most bifid condyle subjects have no complaint related to temporamandibular joint(TMJ), the cases are generally diagnosed through incidental radiographic findings. The case of a 54-year-old female is presented. In a panoramic radiograph obtained after a clinical examination, bilateral bifid mandibular condyle was observed. The open-closed lateral radiograph of the TMJ (obtained using the TMJ-specific program of the panoramic device) demonstrated duplication of the right and left condyles. In order to better evaluate the TMJ morphology and to eliminate pathologies such as fractures that might be missed with conventional radiographs, a computed tomography scan was also obtained. The joint head orientation was observed in the mediolateral direction. The case is discussed in the context of the relevant literature. Until large population-based studies are undertaken and further experimental studies are performed, bifid condyle will remain an incidental finding of anatomic variation rather than a clinically informative observation.
