Recently, a metric approach to skeletal sex determination was published by Paiva and Segre which is based on the summation of two triangular areas defined by three distinct craniometric landmarks: Porion, Mastoidale, and Asterion. According to the authors, values for the total triangle > or =1447.40 mm(2) are characteristic for male crania, while values < or =1260.36 mm(2) are indicative of female skulls (95% confidence). In order to evaluate the method's validity, two sex- and age-documented samples of different provenience were analyzed (N=197). The results show that while the indicated measurements display significant sex differences, the technique is of little practical meaning where a single individual must be independently classified. It is hypothesized that differences in the expression of sexual dimorphism as well as a population-specific variability of the asterion location undermine the value of the mastoid triangle as a sex determinant.
最近，派瓦和塞格雷发表了一种基于骨骼性别判定的度量方法，该方法基于由三个不同的颅骨测量标志点（耳点、乳突尖和星点）所定义的两个三角形区域的总和。据作者称，总三角形面积大于或等于1447.40平方毫米的值是男性颅骨的特征，而小于或等于1260.36平方毫米的值则表明是女性头骨（95%置信区间）。为了评估该方法的有效性，对两个来源不同、有性别和年龄记录的样本（N = 197）进行了分析。结果表明，虽然所指示的测量显示出显著的性别差异，但在必须对单个个体进行独立分类时，该技术几乎没有实际意义。据推测，性二态性表达的差异以及星点位置的群体特异性变异削弱了乳突三角形作为性别决定因素的价值。
