西安地区汉族青年面部形态角度相关性的初步研究

摘要

目的：观察分析西安地区汉族青年面部形态角度的相关性。方法：纳入面形正常无手术及外伤史的西安市汉族18～40岁居民60名（男女各30名），进行头面部三维立体扫描，用3dMD 软件自带测量系统在扫描影像上定点并测量面部12个常用角度，用 SPSS 19．0将结果进行统计分析，计算面部各角度之间的相关性及相关性回归公式。结果：获得12个面部角度的均值及标准差，男性鼻额角大于女性（P ＜0．05），其余角度无性别差异（P ＞0．05），5个角度之间存在7组相关关系（R≥0．7），其中4组为正相关，3组为负相关；得到7个相关性回归方程。结论：面部角度之间彼此协调相关。%Objective:To explore the correlativity between facial morphologic angles of Xi'an youths.Methods:60 Xi'an residents aged 18 -40 years(30 males and 30 females)with normal facial profile,without operation and trauma experience,received 3dMD scaning.12 morphologic angles were measured.Data were statistically analysed by SPSS 19.0 software.The correlative relationship and formulas of facial angles were studied.Results:Nasofrontal angle of the males was larger than that of the females(P <0.05), the other angles showed no difference between sexes(P >0.05).Correlativity between each pair of 5 angles was concluded by a logic diagram(R≥0.7),the correlativity of 4 pairs was positive and 3 negative.Conclusion:The facial morphologic angles of Xi'an youths are correlated and coordinated.
