Diagnosis of Temporomandibular Joint Arthrosis 2. Arthroscopic Differentiation

Arthroscopy was performed on 43 joints of 34 patients with painful locking of the temporomandibular joint. The subjects were 32 joints with closed-lock (non-reducible anterior disk displacement) and 11 joints with osteoarthrosis, consisted of 8 males and 26 females, from 15 to 69 years old with an average of 38.5 years. In closed-lock joints, synovitis on the posterior pouch, fibrillation of the eminence, fibrous adhesion from the anterior pouch to medial capsule were observed. On the other hand, joints of osteoarthrosis disclosed extensive synovitis, fibrillation and adhesion. Discal perforation was indicated in only one joint with closed-lock and 5 joints with osteoarthrosis arthroscopically. These arthroscopic findings could clarify the intra-capsular pathosis of two TMJ disorders, also differentiate them each other.
