Osteochondrosis dissecans of the temporomandibular joint: a case report and a review of literature.

A case of a 71-year-old female patient with osteochondrosis dissecans of the right temporomandibular joint is presented. Osteochondrosis dissecans usually occurs at the weight-bearing convex cartilage in all larger joints. It is rarely found in the temporomandibular joint and usually shows one or two loose bodies dislodged from defects which are present on the condylar head. Because of multiple loose bodies and a defect on the temporomandibular fossa, the case presented here is very uncommon.
