摘　　要：目的 :建立一个强调前后向指标的软组织头影测量分析法。方法 :在垂直于自然水平面并经过软组织鼻下点的垂线参考平面建立后 ,13个垂直间距及 5个软组织突距分别从 6 6个中国年轻正常 (33名男性 ,33名女性 )的头颅侧位片中获得。结果 :在性别二态性比较上看 ,男性组比女性组多数指标有显著增大的绝对值 ,但在某些测量项目上 ,如G -VL ,NT -VL ,As-VL ,ULA -VL ,B -Bs ,Pog -Pos等间距男女无显著性差异。结论 :女性在软组织发育有关的项目上 ,并没有表现出比男性明显的弱势。另外 。Objective:To present a new soft tissue cephalometric analysis tool which emphasizes on anteroposterior facial dimensions.Methods:A vertical reference line through subnasale based on natural head position was established.Thirteen linear variables of vertical distances and five soft tissue thickness variables were obtained from lateral cephalograms of 66 Chinese young adults(33 males,and 33 females) with normal occlusion Results:Sexual dimorphism,with larger dimensions in males than in females,was most pronounced to the vertical plane,whereas some other variables did not show significant differences between males and females,such as the distance of G-VL,NT-VL,As-VL,ULA-VL,B-Bs,Pog-pos.Conclusion:It is suggested that females are not inadequate in facial development as in males.Moreover,the article showed an useful way for improving the quality of cephalometric images.
