A massive osteochondroma of the mandibular condyle.

A case is presented of a massive osteochondroma of the mandibular condyle leading to marked facial asymmetry, painful mastication, disturbed occlusion and impaired hearing on the affected side. The diagnosis was confirmed by radiological and histological examination. A tentative treatment plan including surgery on both jaws was proposed but had to be modified because of the patient's reluctance to undergo any surgery on the maxilla.
