Arthrotomographic evaluation of the temporomandibular joint.

Abstract

Thirty-five arthrotomograms of the temporomandibular joint (TMJ) were done on 33 patients who had chronic pain and dysfunction of the TMJ. All patients were refractory to conservative treatment. Five arthrotomograms were normal; abnormalities were observed in 30. Abnormalities of the meniscus were anterior dislocation, anterior subluxation, perforation, tenting, and degenerative changes and adhesions. The significance of these abnormalities is discussed. Arthrotomography was found to be an integral part of the diagnosis and treatment of TMJ disorders.
