[Technique and interpretation of arthrography of the temporomandibular joint. Study of 120 cases].

Abstract

The goal of the study was to assess the predictive value of inferior joint space arthrography for detection of abnormalities found during surgery. Therefore, a retrospective analysis of arthrographic and surgical findings in 120 joints was performed. Arthrography showed high accuracy for detection of anterior disk displacement (90%) and disk perforation (90.8%). The shape of the anterior recess proved to be the most valuable arthrographic criterium for detection of anterior disk displacement. Cinematographic registration of joint dynamics after injection of contrast material and arthrotomographic analysis of the shape of the superior margin of the anterior recess of the inferior joint space were necessary for an optimal evaluation of the disk position.
