Abstract
Surgical therapy can be recommended for some types of internal derangement of the temporomandibular joint (TMJ) or degenerative arthrosis of the TMJ. Temporomandibular articular discectomy may also be saitable for terminal stage internal derangement of the TMJ. Recent studies suggest the beneficial use of autogenous auricular cartilage interpositional graft after discectomy. In this report, four cases of degenerative joints were treated by discectomy with ear cartilage interpositional graft, because they made little remission with preservative therapies. Their preoperative MR Images showed anterior disk displacement without reduction. Postoperative courses have been good. Their trismus improved with widening of the maximal range of opening. Chewing and opening pain were reduced. Postoperative evaluation was carried out. The criteria for TMJ meniscus surgery of the American Association of Oral and Maxillofacial Surgeons was applied to each case. As a result, three cases were excellent and one case was good. To achieve these results, careful long term follow up is needed.
