摘　　要：目的确定髁状突移动度与关节病严重程度的关系，以及探明该指标与临床易测得指标如张口度、前伸度的关系。方法对１３３例２６６侧关节的个体校正侧位中份断层造影片上髁状突张闭口时的最大移动度进行了测量，并将该值与临床测量指标联系起来进行分析。结果我们发现：①颞颌关节紊乱症状器质型与非器质型髁状突移动距有显著差别；②髁状突移动度与最大张口度、最大前伸度、下颌左或右偏转距之间存在正相关及直线回归关系。结论Ｘ线片上髁突移动度是颞颌关节紊乱的重要诊断指标之一。Abstract Objective To determine the diagnostic value of condylar movement (CM) and relationship between CM and easilly obtained clinical variables such as maximum opening distance (MOD), maximum protrution distance (MPD) etc. which are considered as index of severity of craniomandibular disorders (CMD). Methods The CM were measured on the films reflecting middle section of the TMJ taken by lateral tomography in 133 case (266 TM joints) with CMD. The data were analysed using correlation and regression analysis. Results It was concluded that. 1.CMs were significantly different between groups with organic pathology or non organic pathology determined by X ray examinations. 2.CMs were positively correlated with MOD,MPD, laterotrution distances, and there were linear regreesion relationship between CM and other measurements of the mandibular movement. Conclusion CM can be viewed as diagnostic variable of CMD
