266 sagittal tomographs corresponding to the left and right temporo-mandibular joints of 133 patients were divided into 7 groups according to the absence or presence of functional disturbances or of organic lesions. The statistical analysis of the values obtained from a "triangular study" of the surface of the glenoid fossa and of the mandibular condyle showed the following: - the average surface area of the glenoid fossa does not significantly differ from one to the other of the 7 groups examined - the average surface of the mandibular condyle did not significantly vary between groups - in no group studied, except the F/P group (function disturbances/small displacement), was there any relationship between the surface of the glenoid fossa and that of the condyle. It can, however, be stated that the relationship between the surface of the glenoid fossa and the mandibular condyle would seem to play a role in the degree of displacement of the condyle during full opening of the mouth.
对133例患者左右颞下颌关节对应的266张矢状断层图像，根据是否存在功能障碍或器质性病变分为7组。对关节盂表面和下颌髁突进行“三角研究”所得数据的统计分析结果如下：- 在所检查的7组中，关节盂的平均表面积在各组之间无显著差异- 下颌髁突的平均表面积在各组之间无显著变化- 除F/P组（功能障碍/小移位）外，在所研究的任何组中，关节盂表面与髁突表面之间均无关联。然而，可以说关节盂表面与下颌髁突之间的关系似乎在张口时髁突的移位程度中起作用。
