基于CT的中国汉族成人眼眶测量与分析

CT-based measurement and analysis of the orbit of adults of Han nationality

目的：通过对中国汉族成人眼眶的测量,分析其与性别的关系。方法：采用西门子16层螺旋 CT 对实验者进行扫描,使用 VG Studio 2.2 MAX 软件提取三维颅骨并对颅骨数据进行三维坐标测量。使用 WinEDMA1.0.1软件对三维坐标数据进行形状差异分析并对形状差异进行 bootstrap 非参数检验。结果：欧几里德几何距离矩阵分析显示,辽宁地区成年男性与女性眼眶形状有显著差异,bootstrap 非参数检验 T=1.169,P =0.001。形状差异矩阵（FDM）比值（女性比男性）中对差异有贡献的比值即小于0.95和大于1.05的部分,小于0.95的占36%,大于1.05的占2%。结论：辽宁地区成年男性与女性眼眶形状有显著差异；造成男性和女性眼眶形状差异的主要原因是左右侧眼眶相对空间位置不一致。

Obj ective ：To measure the orbits of adults of Chinese Han nationality and analyze their relationship with gender. Methods ：The experimenters were scanned using Siemens 1 6 layers spiral computer tomography （CT）.3D skull was extracted and three-dimensional coordinate measurement about the data of the skull was performed using VG Studio 2.2 MAX software. The shape differences of the three-dimensional coordinate data was analyzed using WinEDMA 1.0.1 software and the bootstrap nonparametric test was done on the shape differences.Results ：The EDMA analysis showed that orbital shapes of male and female adults differed significantly in Liaoning province,bootstrap nonparametric test T=1.1 69,P =0.001 .Form Difference Matrix （FDM）ratio women to men contributes to the difference in the ratio is less than 0.95 and a part of the greater than 1.05 and less than 0.95 with 33 accounted for 36% （33/9 1 ）,and greater than 1.05 has two accounted for 2%（2/9 1）.Conclusion：Orbital shapes of male and female adults has significant differences in Liaoning province.The main reason for the differences is that the relative space position of the left orbit and the right orbit is inconsistent.The gender differences in the orbital shape is bigger in the left eye than that in the right eye.
