抄録

Synovial osteochondromatosis is a benign lesion of synovial membrane origin. It occurs most often in the metaphyseal regions of long bones, and is relatively uncommon in the temporomandibular joint. We report a case of Synovial osteochondromatosis of the temporomandibular joint with hypertrophy of the condyle. The patient was a 66-year-old man, complaining of dull pain in the right temporomandibular joint. Radiographic examination, CT scanning, and the double contrast arthrographic findings showed that the right condyle was enlarged with irregular radiopaque masses lying above the external of the condyle. Also, there was a perforation of the disk, and the joint space had narrowed. Bone scintigraphic findings showed a hot spot at the right mandibular head. We operated on this patient with a clinical diagnosis of tumor of the mandibular head, but histopathological examination showed Synovial osteochondromatosis. There were no significant complications at 1 year and 7 months after the operation.
