26 cases with Temporomandibular Joint Dysfunction Syndrome (TMJDS) were included in the present study. Fully corrected lateral tomogrames of TMJ in the intercuspid position were taken for all the cases; and fully corrected lateral arthrotomogrames were taken for 19 cases (21 joints) of them. The area and linear measurements of the joint space were made with the aid of computer. The results showed that the position of the condyle in the patients with TMJDS was located in the posterior position of the fossa. Statistics results showed that there was significant difference between the patient group and control group. Although the posterior displacement of the condyle was often associated with the anterior displacement of the disc, it was not always agreement with the anterior disc displacement. So, the exact diagnosis of disc displacement should be still on the basis of arthrography or other examinations, such as CT or MRI.
本研究纳入了26例颞下颌关节紊乱综合征（TMJDS）患者。对所有病例均拍摄了正中牙合位时颞下颌关节的全校正侧位断层片；其中19例（21个关节）拍摄了全校正侧位关节造影断层片。借助计算机对关节间隙进行面积和线性测量。结果显示，TMJDS患者髁突位置位于关节窝后方。统计结果表明，患者组与对照组之间存在显著差异。虽然髁突后移位常与盘前移位相关，但并不总是与盘前移位一致。因此，盘移位的准确诊断仍应基于关节造影或其他检查，如CT或MRI。
