This article presents the results of a validation study of a previously published method of sex determination from the temporal bone. The purpose of this study was to evaluate the lateral angle method for the internal acoustic canal for accurately determining the sex of human skeletal remains using measurements taken from computed tomography (CT) scans. Previous reports have observed that the lateral angle size in females is significantly larger than in males. The method was applied to an independent series of 77 postmortem CT scans (42 males, 35 females) to validate its accuracy and reliability. The mean lateral angle of the internal acoustic canal was found to be larger in females (46.5°) than in males (43.4°). However, the difference was not statistically significant and the sex differences reported in previous studies were not substantiated. In light of the observed results, the lateral angle method appears to be of minimal practical use in forensic anthropology and archeology.
本文介绍了一项对先前发表的一种从颞骨确定性别的方法的验证研究结果。本研究的目的是评估内耳道的外侧角法，通过从计算机断层扫描（CT）扫描获取的测量数据来准确确定人类骨骼遗骸的性别。先前的报告指出，女性的外侧角尺寸明显大于男性。该方法应用于77例独立的死后CT扫描（42例男性，35例女性），以验证其准确性和可靠性。结果发现，女性内耳道的平均外侧角（46.5°）大于男性（43.4°）。然而，这种差异没有统计学意义，先前研究报告的性别差异并未得到证实。鉴于观察结果，外侧角法在法医人类学和考古学中的实际应用价值似乎极小。
