摘要
为探讨髁突在关节窝位置对ＴＭＪＤＳ结构紊乱的诊断意义，作者选择颞下颌关节紊乱综合征结构紊乱患者２６例，均拍摄关节完全矫正关节侧位体层片，并利用计算机技术进行关节间隙的面积及线性测量。其中１９例（２１侧）进行关节上腔造影检查。结果表明：颞下颌关节结构紊乱患者课突位置呈明显后移位，与健康对照组比较有显著性差异。虽然髁突后移位与关节盘前移位有一定相关性，但不尽一致，关节盘前移位的诊断最终仍需依靠关节造影或ＣＴ、磁共振等医学检查。
Abstract26 cases with Temporomandibular Joint Dysfunc-tion Syndrome (TMJDS) were included in the presentstudy. Fully corrected lateral tomogrames of TMJ in theintercuspid position were taken for all the cases;and ful-ly corrected lateral arthrotomogrames were taken for 19cases (21 joints) of them. The area and linear measure-ments of the joint space were made with the aid of com-puter. The results showed that the position of thecondyle in the patients with TMJDS was located in theposterior position of the fossa. Statistics results showedthat there was significant difference between the patientgroup and control group. Although the posterior dis-placement of the condyle was often associated with theanterior displacement of the disc, it was not always a-greement with the anterior disc displacement. So, theexact diagnosis of disc displacement should be still onthe basis of arthrography or other examinations , such asCT or MRI.
