摘　　要：目的:探讨不同垂直骨面型成年骨性Ⅲ类患者的髁突形态特点及差异,为临床诊疗提供一定的参考依据。方法:采用计算机辅助X线头影测量技术,对不同垂直骨面型成年骨性Ⅲ类患者的全颌曲面断层片进行测量,比较各组间髁突形态特点。结果:不同垂直骨面型成年骨性Ⅲ类患者各组髁突形态测量值,髁突上部高度h值、升支高度RH值及h/RH值无统计学差异(P>0.05)。H/W值,不同垂直骨面型组间有显著性差异(P<0.01),高角组分别大于均角组和低角组。结论:不同垂直骨面型成年骨性Ⅲ类患者的髁突形态存在差异,这可能与不同垂直骨面型的生长型有关。Objective：To study the difference of condylar morphology with different vertical facial types of skeletal Ⅲ malocclusions in adults. Method： Cephalograms of 60 adults with different vertical facial types were retrospectively investigated by computerized cephalometric analysis.Condylar morphology were compared among different vertical facial type groups. Result： There was no significant difference in upper condylar height, ramus height and the upper condylar height to the ramus height radio in the groups. There was statistical difference in the condylar height to the condylar neck width ratio in the groups（P〈0.01）. The ratio of high angle group is higher than average angle group and low angle group.Conclusion：In adults of skeletal Ⅲ malocclusions with different vertical facial types,there are statistical differences in condylar morphology, which might be due to different growth of mandibular.
