Osteoarthrosis deformans of the temporomandibular joint (TMJ) is a painful disease characterized by localized osseous changes in the moving parts of the joint.<BR>In this article, a case of a 28-year-old man with osteoarthrosis treated by right-sided high condylectomy was described. His complaint was limitation of mouth opening, jaw noise and severe right-sided facial pain during talking or eating.<BR>Radiographic findings revealed bony spicule formation on the surface of time right condyle. Because of no response to the conservative treatment for two weeks, we performed the high condylectomy with preservation of the meniscus as described by Henny.<BR>The surgical specimen showed a sharp bony protuberance on the articular surface. Postoperatively, he had complete relief of symptoms and returned to normal jaw function. From this case, we appreciated that high condylectomy had definite place in the treatment of patients with demonstrable articular pathology, severe pain arising from the TMJ, and no response to usual conservative therapy.
