Abstract

Forty-one closed lock cases were subjected to arthroscopic examination, and the relation between the presence of adhesion in the upper joint cavity and the change of mouth opening range after local anesthesia to the temporomandibular joint was evaluated.<BR>In patients with adhesion, the change of mouth opening range after local anesthesia to the temporomandibular joint was smaller than that in patients without adhesion. In patients whose mouth opening range became more than 39mm and increased by over 11mm after local anesthesia, adhesion in the upper joint cavity was observed in 0%. On the other hand, in patients whose mouth opening range became less than 38mm or increased by under 10mm after local anesthesia, the prevalence of adhesion was 80% and 75%, respectively.<BR>In order to diagnose adhesion before pumping or arthrocentesis, measurement of mouth opening range after local anesthesia to the temporomandibular joint is an easy and effective procedure.
