Fibrous ankylosis of the temporomandibular joint: report of a case with atypical presentation.

A case of chronic unilateral mandibular dislocation with development of fibrous ankylosis is presented. This was an unusual presentation of intracapsular tissue ankylosis to the eminentia, as well as retrocondylar cicatrix combined with contralateral mandibular osseous compensations and remodeling with resulting ramus impingements upon relocation of the condyle. Various diagnostic and therapeutic considerations are reviewed and discussed.
