Abstract
OBJECTIVE: This study aimed to compare ultrasonography (US) with magnetic resonance imaging (MRI) with respect to the diagnosis of temporomandibular joint (TMJ) internal derangements. STUDY DESIGN: The study group consisted of 23 patients with a chief complaint of TMJ discomfort who were tentatively diagnosed by means of head-neck examination as having TMJ internal derangements and a control group of 9 volunteers who had no sign of TMJ internal derangements. All the patients were then examined by means of MRI and US. RESULTS: The results showed perfect agreement between MRI and US in the diagnosis of TMJ internal derangements (kappa = 1.000; P =.0001). CONCLUSION: MRI and US can be used to define the disk and its position, as well as the presence of TMJ internal derangements.
