西安地区汉族青年颅面部比例的研究

Proportion Index of Craniofacial Areain Xi`an Normal Adult

目的 建立西安地区汉族青年正常牙合颅面部水平、垂直向的比例指数 ,为临床治疗提供参考依据。方法 采用Farkas建立的面部形态直接测量法 ,对 10 0例 (男、女各 5 0名 )西安地区身体健康、颅颌关系协调、牙齿排列整齐、I类牙合关系、正常覆盖、覆牙合、无牙病治疗史及外伤史的年满 18岁的汉族高中生 ,进行颅面部软组织 2 3项测量 ,建立 3 6项水平、垂直向比例指数。测量结果经Spss10 .0统计软件处理 ,并进行男女两组的t检验。结果 男、女之间面部高度的比例指数均存在显著差异 ,涉及眼、鼻的比例 ,男女之间存在较大差异 ,其中两眼内眦宽略小于鼻宽 ,略大于眼裂宽 ,鼻宽稍大于 1/ 4面宽 ,约为 4/ 5眼裂宽。结论 男、女之间面部比例不同 ;

Objective XTo investigate the horizontal and vertical proportional relationships in craniofacial area and to establish the base for treatment craniofacial abnormality. Methods 100 health students in middle school ( 50 males, 50 females) with harmony craniofacial morphology, without malocclusion , without dental ill and trauma history , average age 18 years old, were measured by Farkas` direct measurement. We measured 23 items in order to form 36 indices . The measurement results were statistically analyzed by SPSS10.0 software in t test between the male and female. Results There was significant difference in vertical proportion of the face between sexes ( P < 0.05 ). The mean intercanthal width(en-en)was slightly shorter than nose width (al-al); The mean intercanthal width(en-en)was slightly longer than eye fissure width(ex-en); nose width(al-al) was slightly longer than 1/4 of face width (zy-zy); nose width (al-al)was about 4/5mouth width (ch-ch)?Conclusion 1. The indices were difference between sexes. 2. Comparing neoclassical canons of facial proportion , the results of the present study were not identical.
