Arthroscopic findings observed in the lateral and endaural approaches, and the subsequent dissections were compared in the upper joint compartments of 15 temporomandibular joints of 8 cadavers. Most of all arthroscopic findings to [S] synovial tissue degeneration, [Ar] articular fibrocartilage/disk surface degeneration, [Ad] adhesion and [P] perforated disk had good correspondence to the findings of dissections. The findings of [S] and [P] had high sensitivity (true positive rate 0.89~1.00) and high specificity (true negative rate 0.92~1.00), they had high diagnostic accuracis. The specificity (0. 75) of [Ar] was not high because of two false positives obtained from the enlarged images in arthroscopy compared with in dissections. This meant, however, arthroscopy was suitable for the precise diagnosis of IAt}. Tne sensitivity (0.67) of [P] was not high because of a false negative obtained from that the adhesion of anterolateral synovial portion was not able to be found. This meant the visible fields depended on arthroscopic approaches to the temporomandibular joints. These data confirmed that arthroscopy was an effective method to investigate the condition of temporomandibular joints, especially in precise diagnosis. On the other hand, it was shown that there was a little area, anterolateral synovial portion by means of lateral and endaural approaches, not to visualize in arthroscopy.
