顎関節疾患に対する関節鏡視下結節形成術の経験

抄録

The purpose of this clinical study was to evaluate arthroscopic eminoplasty in several temporomandibular joint (TMJ) disorders. Fifteen joints in 10 patients were studied. The diagnoses were osteoarthrosis (7 joints), habitual luxation (4 joints), internal derangement with click (1 joint), and eminence click (3 joints). The articular eminence was shaved for 2-5 mm in height by employing an electric motoring shaver and round burs. Alleviation of symptoms was obtained in habitual luxation and eminence click. On the contrary, it was difficult to assess the effect of surgery on osteoarthrosis in a short period. In conclusion, the present study indicated that arthroscopic eminoplasty can be performed clinically, however, further studies are necessary to establish the adequate indications and investigate the postoperative healing process.
