Diagnosis of Temporomandibular Joint Arthrosis 1. Arthrographic Differentiation

Arthrotomography of the temporomandibular joint was performed on 207 joints of 148 patients by puncturing inferior and superior joint compartments and injecting water-soluble contrast medium under fluoroscopy. Symptoms of these subjects were arthralgia, noise and hypomobility of the temporomandibular joint. In the results, 16 joints (7.7%) were normal, 31 joints (15.0%) with reducible anterior disk displacement (click), 143 joints (69.1%) with non-reducible anterior disk displacement (closed-lock), and 17 joints (8.2%) with stenosis or adhesion of the joint compartment. Among the all joints, 13 joints (6.3%) associated with discal perforation.  These findings indicated several intra-capsular organic changes, moreover has a significance in differential diagnosis and treatment for the patients with temporomandibular joint arthrosis.
