Sixty-seven patients, who were surgically treated for internal derangement of the temporomandibular joint (TMJ), were retrospectively examined. The patients were evaluated preoperatively by clinical and arthrographic examinations and these results were compared with findings at surgery. Partial or complete dislocation of the disc was detected by arthrographic examination in 65 joints. Actual disc displacement was demonstrated at surgery in 57 TMJs, giving arthrography a positive predictive value of 88% for detecting disc dislocation. Arthrographic diagnosis of disc perforation was unreliable, as both false positive and false negative observations were recorded. Arthrography was found to have a positive predictive value of only 53% for assessing disc perforation. Based upon its proven inaccuracy, invasiveness and discomfort to the patient, it is recommended to replace arthrography by magnetic resonance imaging.
对67例接受颞下颌关节（TMJ）内紊乱手术治疗的患者进行了回顾性检查。术前通过临床和关节造影检查对患者进行评估，并将这些结果与手术结果进行比较。关节造影检查在65个关节中检测到部分或完全性盘状移位。手术中在57个颞下颌关节中证实了实际的盘状移位，关节造影对检测盘状移位的阳性预测值为88%。关节造影对盘状穿孔的诊断不可靠，因为记录到了假阳性和假阴性观察结果。关节造影对评估盘状穿孔的阳性预测值仅为53%。基于其已被证实的不准确、有创性以及给患者带来的不适，建议用磁共振成像取代关节造影。
