In treating habitual dislocation of TMJ, generally there are two ways; conservative and open surgery, Conservative treatment has a high recurrence rate and open surgery involves surgical invasion. Consequently, many results of conservative and open surgery were unsatisfactory. Arthroscopic surgery for habitual dislocation of the TMJ solved the problems above. It is useful due to little recurrence, reducing surgical invasion and simple technique. Arthroscopic surgery was performed for on 18 cases out of 19 joints of patients who visited out hospital from May, 1989 to June, 1995.
18 cases of 19 joints after initial surgery showed good results and only one joint had recurrence. Even that one case improved after secondary arthroscopic surgery. Therefore, surgical arthroscopy is thought to be the best method for habitual dislocation of TMJ.
