新疆喀什地区维吾尔族青年面部三维扫描的形态学研究

目的:利用三维扫描技术获取新疆喀什地区维吾尔族青年人群颌面部二维及三维数据,比较维吾尔族男性与女性面部差异性。方法:采用3DCaMega光学三维扫描仪收集341例维吾尔族样本,男性116例,女性225例,应用Geomagic studio软件对数据进行重建、定点、测量、验证测量值可重复性、测量标志点间的平面距离及曲面距离,应用SPSS24.0软件进行统计学分析。结果:9个测量指标重复性好(P>0.05),比较维吾尔族男性及女性面部距离参数,其中两眼间距、外眦间距、鼻长、面下1/3高度,平面与曲面测量值男女间均存在显著差异(P<0.05);额高、鼻宽平面测量值无统计学意义(P>0.05),曲面测量值有统计学差异(P<0.05)。结论:三维面部测量的方法在反映面部复杂结构的差异性方面更加精确,是一个有价值、可靠人体测量学工具。

Study on Facial Morphology of Uygur Youth using 3D Scanning in Xinjiang Area of Kashi

Objective: To compare the differences between 2D and 3D measurements of facial morphology of Uygur youthful males and females by using 3D scanner scanning in Xinjiang area of Kashi. Methods: Data from 341 healthy Uygur individuals were collected by 3DCaMega scanner (male 116 and female 225). Geomagic studio software was used to reconstruct 3D morphology, mark landmarks, set 3D coordinate system, confirm the reproducibility of the measurement, and measure 2D and 3D distances between landmarks of each sample. Results: All 9 measurements were confirmed perfect reproducibility (P>0.05). Comparison of facial distance parameters between Uygur males and females. There were significant differences between 2D and 3D distances for Len-Ren, Lex-Rex, N'-Sn and Sn-Mes measurements. No difference was found for Tr-N' and Lal-Ral measurements in 2D distances (P>0.05), but significant diffierence existed in 3D distances (P<0.05). Conclusion: 3D facial measurement is an accurate and reliable anthropometric method to reflect the differences of complex structures of human face.
