Abstract

The present study was designed to measure and compare various measurements of orbital apertures between male and female subjects using digital computed tomography. Also to assess the usefulness of orbital aperture measures as an aid in sex determination in sample of Egyptian population. The study included 92 subjects (44 males and 48 females) with age ranged from 18 to 65 years. The results showed that males exhibited greater mean values for all the measurements except for left orbital width that was slightly increased in females. There were significant differences (p < 0.05) between males and females regarding right orbital height, right and left area and inter zygomatic distance. The accuracy of correct sex classification was achieved up to 74.7%. Discriminant analysis revealed that inter zygomatic distances showed significant discrimination (p = 0.028) between both sexes. Receiver operating characteristic (ROC) curve analysis for sex discrimination demonstrated that inter zygomatic distance at a cutoff of 96.7, had sensitivity of 76.7%, specificity of 65% and accuracy 71% (p < 0.001). In conclusion, inter zygomatic distance was found to be the best reliable parameter and achieved the highest accuracy 71%. So, it was seen that inter zygomatic distance could be used for the sex determination from computed tomography.

使用计算机断层扫描从轨道孔径尺寸的性别歧视:埃及人口的样本
本研究的目的是测量和比较使用数字计算机断层扫描在男性和女性受试者之间的眼眶孔径的各种测量。同时评估轨道孔径测量在埃及人口性别确定中的辅助作用。该研究包括92名受试者(44名男性和48名女性),年龄从18岁到65岁不等。结果表明,除了左眼眶宽度外,男性在所有测量值中均表现出更高的平均值,而女性则略有增加。男女在右眼眶高度、左右面积、颧间距离上差异有统计学意义(p < 0.05)。正确的性别分类准确率达74.7%。判别分析显示,颧骨间距离在两性间存在显著差异(p = 0.028)。性别歧视的受试者工作特征(ROC)曲线分析显示,颧间距离在截断值为96.7时,敏感性为76.7%,特异性为65%,准确性为71% (p < 0.001)。结论:颧间距离是最可靠的参数,准确率最高达71%。由此可见,颧骨间距离可用于计算机断层扫描的性别判定。
