Human hyoid is sexually dimorphic and is useful for sexing unknown skeletal remains. We aimed to find sex prediction potential of three linear dimensions of hyoid bones obtained from a series of cadavers with Persian ethnicity.
This cross-sectional study was carried out in 2015 at Forensic Pathology Organization of Tehran, Iran. We directly measured three linear dimensions of a series of hyoid samples obtained from cadavers during their neck autopsy in a convenience method. These dimensions were width, length and distance between lesser horns of hyoid. Height and weight of cadavers were also documented. Cadavers were of Persian ethnicity and at least 25-year-old. Data were analyzed by SPSS16. Logistic Regression Model was applied to find independent sex predictor(s) of hyoid. Statistically significant level was considered <0.05.
Hyoids of 349 adult cadavers (176 females and 173 males) with mean±SD age of 39.91±8.13years were investigated. Male cadavers had significantly higher BMI values (p-value<0.001). Mean±SD for width, length and distance between lesser horns of hyoids were 34.45±4.70, 34.61±4.67 and 22.71±2.80mm, respectively. All measured dimensions had greater mean values in males (all with p-values<0.001). After adjusting for BMI, length and distance between lesser horns of hyoid were independent predictors of sex with odd's ratio of 4.67 and 1.97, respectively. Combining these two measurements provided sex classification accuracy of 97.4%.
Special metric hyoid indicators can help in accurate sexing of skeletal remnants of adult Iranians. Further studies will find the strongest sex predictors of hyoid bones among Persians.
人类舌骨具有性别差异，有助于对未知骨骼遗骸进行性别鉴定。我们旨在从一系列具有波斯族裔的尸体中获取舌骨的三个线性维度，以寻找其性别预测潜力。
这项横断面研究于2015年在伊朗德黑兰法医病理组织进行。我们采用便利抽样的方法，在尸体颈部尸检过程中直接测量了一系列舌骨样本的三个线性维度。这些维度分别是舌骨的宽度、长度以及小角之间的距离。同时记录了尸体的身高和体重。尸体均为波斯族裔，年龄至少25岁。数据采用SPSS16进行分析。应用逻辑回归模型寻找舌骨的独立性别预测指标。统计学显著性水平设定为<0.05。
对349具成年尸体（176名女性和173名男性）的舌骨进行了研究，尸体的平均年龄为39.91±8.13岁。男性尸体的BMI值显著更高（p值<0.001）。舌骨的宽度、长度以及小角之间距离的平均值±标准差分别为34.45±4.70、34.61±4.67和22.71±2.80毫米。所有测量维度在男性中的平均值均更大（所有p值<0.001）。在调整BMI后，舌骨的长度和小角之间的距离是性别的独立预测指标，其比值比分别为4.67和1.97。将这两项测量结果相结合，性别分类准确率为97.4%。
特定的舌骨测量指标有助于准确鉴定成年伊朗人的骨骼遗骸性别。进一步的研究将找出波斯人中舌骨最强的性别预测指标。
