The significant role of the petrous bone in sex assessment of skeletal human remains has been highlighted by several studies. In previous work we applied the method of the measurement of the lateral angle of the petrous bone to a sample of cremated human remains of known age and sex from an Italian crematorium; the low accuracy of sex classification obtained was probably due to the high number of elderly individuals in our sample. In this paper we investigate the relationship between age and alterations of the petrous bone, by applying the same methodology we used previously, measuring the lateral angle of the petrous bone, in a new sample group that was subdivided into three different age groups. Results showed a moderate rate of accuracy in sex assessment for the first two age groups, for which a new sex-discriminating sectioning point was found; however, the method was found not to be applicable for individuals over 70 years of age. Measurement of the lateral angle in adults aged between 20 and 70 years is a reliable method for sex assessment of cremated remains in conjunction with classical methods, in both archaeological and forensic contexts.
多项研究突出了颞骨在人类骨骼遗骸性别评估中的重要作用。在之前的工作中，我们将测量颞骨外侧角的方法应用于来自意大利一家火葬场的已知年龄和性别的火化人类遗骸样本；所获得的性别分类准确率较低，可能是因为我们样本中的老年人数量较多。在本文中，我们通过应用之前使用的相同方法，即测量颞骨外侧角，在一个新的样本组中研究年龄与颞骨变化之间的关系，该样本组被细分为三个不同的年龄组。结果显示，前两个年龄组在性别评估中的准确率适中，为此找到了一个新的性别区分分界点；然而，该方法被发现不适用于70岁以上的个体。在考古和法医背景下，测量20至70岁成年人的外侧角是一种与传统方法相结合的可靠的火化遗骸性别评估方法。
