摘要
目的了解舌骨的形态特征,分析其性别差异以及法医学意义。方法收集成人尸体的舌骨68例,加温后除去多余的软组织,肉眼观察舌骨体与舌骨大、小角连接的性质,形态特征及其骨化程度,测量舌骨体高和舌骨体弓高,并比较两者在男、女两性间差异,推导舌骨性别的判别分析方程。结果获得了双侧完全骨化、双侧无骨化、双侧部分骨化、单侧完全骨化(另一侧部分骨化)、单侧完全骨化(另一侧无骨化)5种骨化连接状态,且男性舌骨弓高(x1)和舌骨体高(x2)均大于女性(P<0.01),舌骨性别(y)的最佳判别分析方程:y=0.438x1+1.042 x2-12.979,判别值为-0.272 5,判别率为88.2%。结论根据舌骨的形态性别特征,可为法医鉴定实践提供帮助。
Objective gender difference in To understand and analyze the morphological characteristics of hyoid bone and its order to find out its forensic significance. Methods The hyoid bones of 68 adult corpses were dissected from redundant soft tissues after heating. The connection status of body of hyoid, greater cornu and lesser cornu, the morphological characteristics of hyoid bone and the degree of ossifi- cation were observed by visual inspection. The height of hyoid bone and the arched height of hyoid bone were measured and compared the differences between male and female in order to deduce the analytic equation for gender estimation by hyoid bone. Results Five connection conditions of hyoid bone were identi- fied by the morphological characteristics, including complete ossification in both sides, no ossification in both sides, partial ossification in both sides, complete ossification in one side （partial ossification in the other side）, and complete ossification in one side （no ossification in the other side）. The values of the arched height of hyoid bone （xl） and the height of hyoid bone （x2） in male were both higher than that in female （P〈0.01）. The analytic equation for gender estimation （y） was y=0.438x1＋l.042x2-12.979. The discriminant value was -0.272 5 and the resolution was 88.2%. Conclusion According to the gender characteristics of hyoid bone, the data of hyoid bone can provide helps for forensic practices.
