摘　　要：目的探讨髁突形态类型与骨性Ⅲ类不同垂直骨面型患者生长发育的关系。方法采用计算机辅助X线头影测量技术,对不同年龄组骨性Ⅲ类不同垂直骨面型患者的全口曲面断层片进行测量,将各组髁突形态进行归类。结果在高角组和低角组中,不同年龄组之间的异常髁突形态分布有差别(P<0.005),且成人组的髁突异常率高于儿童组(P<0.005)。均角组中不同年龄组之间的异常髁突形态分布无差别(P>0.05)。结论骨性Ⅲ类不同垂直骨面型患者的不同年龄阶段的髁突形态类型分布存在差异,这可能与不同垂直骨面型的生长趋势有关。Objective To study the growth of condylar morphology with different vertical facial types of skeletal Ill malocclusions. Methods Cophalograms of 180 skeletal m malocclusions with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Condylar morphology was classified into four types： type A, type B, type C and type D. Comparisons were made among different age groups of the same vertical facial type. Results There was statistical difference in condylar morphology type in high angle group and low angle group.The abnormal type（type C and type D）was getting more by years.There was no significant difference in condylar morphology type in average angle group. Conclusions In the growth of skeletal m malocclusions with different vertical facial types, there are statistical differences in condylar morphology, which might be due to different growths of mandibula.
