Fifty dry skulls were evaluated by means of submental vertex radiographs and axially corrected tomograms. The condyles were classified into four groups according to anterior surface and shape as viewed on the submentovertex radiograph. Thirty condyles were classified as having a flat anterior surface, 27 as convex, 19 as concave, and 24 as triangular. The analysis of variance for the depth of cut demonstrated (1) no statistically significant difference between the condyle/fossa relationship at the various depths of cut for the convex, flat, and triangular condyles and (2) a statistically significant difference between the condyle/fossa relationship of the concave condyles. The difference was significant at the p = 0.107 level for the anterior joint space (A), and at the p = 0.0671 level for the posterior joint space (B). The analysis of variance, in regard to the subject variable, demonstrated a statistically significant difference at the p = 0.0001 level for all condyles.
通过颏下顶点位X线片和轴向校正断层扫描对50个干燥颅骨进行评估。根据颏下顶点位X线片上观察到的髁突前表面和形状，将髁突分为四组。30个髁突被分类为前表面平坦，27个为凸面，19个为凹面，24个为三角形。对截骨深度的方差分析表明：（1）凸面、平坦和三角形髁突在不同截骨深度时，髁突/关节窝关系之间无统计学显著差异；（2）凹面髁突的髁突/关节窝关系之间存在统计学显著差异。在前关节间隙（A）处，差异在p = 0.107水平具有显著性，在后关节间隙（B）处，差异在p = 0.0671水平具有显著性。关于受试者变量的方差分析表明，所有髁突在p = 0.0001水平具有统计学显著差异。
