Dislocation of the mandibular condyle into the middle cranial fossa: report of a case with 5 year CT follow-up.
A 17-year-old patient suffered a dislocation of the right mandibular condyle into the middle cranial fossa following a motorcycle accident. Reduction was delayed because of serious orthopaedic injuries. The condyle was relocated into the glenoid fossa through a combined neurosurgical and preauricular approach. Five years later the patient presented for removal of wisdom teeth and a CT-scan was done to determine the effects of the trauma and management to the condyle. A fibro-osseous ankylosis had occurred in the right temporomandibular joint. The radiological changes confirm that early management appears to improve the prognosis for these injuries.
