Temporo-mandibular joint ankylosis and oro-nasal fistula as complications of facial trauma.

Condylar fractures with or without disruption of the temporo-mandibular joint occur commonly with other facial injuries. The subsequent development of ankylosis presents surgical and anaesthetic problems in management and results in severe physical disability to the patient. Oro-nasal fistula is a rare complication of fractures involving the middle third of the facial skeleton, and two cases are reported.
