Abstract
Dislocation of the mandibular condyle into the middle cranial fossa is a rare complication of mandibular trauma. We report the remarkable case of a 63-year-old patient in whom trauma 54 years prior to consultation resulted in intrusion of the right mandibular condyle into the middle cranial fossa. The diagnosis was missed because of insufficient data provided by conventional radiographies. Failure of timely diagnosis and lack of appropriate treatment resulted in temporomandibular joint ankylosis with functional impairment, disturbance of mandibular growth and dentofacial asymmetry. We emphasize the need for careful radiological investigation in case of a suspected condylar fracture or dislocation, especially when the mechanism of injury is likely to facilitate condylar intrusion. The use of CT and MR-imaging is therefore advocated.
