Superior joint compartment pseudowall in internal derangement with closed lock of the temporomandibular joint was examined arthroscopically in 40 joints of 36 patients. The patients were 2 males and 34 females, with an average age of 37.4 years (13-77 years). In resultant, the pseudowall could be detected in 39 joints (97.5%), in the anterior recess as well as in the lateral aspect of the eminence. The intensity of the pseudowall in each location was found to be mild in 6 joints, moderate in 21 joints, and severe in 9 joints in the anterior recess. On the other hand, the intensity of adhesion was mild in 8 joints, moderate in 12 joints, and severe in 10 joints on the lateral aspect of the eminence.
In conclusion, the pseudowall was cousidered to be significant factor of hypomobility in temporomandibular joint closed locking, which should be detected and treated in a several manner.
