To understand and analyze the morphological characteristics of hyoid bone and its gender difference in order to find out its forensic significance.
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 ossification 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.
Five connection conditions of hyoid bone were identified 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 (x1) 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 = 0.438 x1 + 1.042x2-12.979. The discriminant value was -0.272 5 and the resolution was 88.2%.
According to the gender characteristics of hyoid bone, the data of hyoid bone can provide helps for forensic practices.
了解和分析舌骨的形态特征及其性别差异，以探讨其法医学意义。
对68具成年尸体的舌骨在加热后从多余软组织中分离出来。通过肉眼观察舌骨体、大角和小角的连接状况、舌骨的形态特征及骨化程度。测量舌骨高度和舌骨弓高，并比较男、女之间的差异，以推导舌骨性别判定的分析方程。
根据形态特征确定舌骨有5种连接情况，包括双侧完全骨化、双侧未骨化、双侧部分骨化、一侧完全骨化（另一侧部分骨化）、一侧完全骨化（另一侧未骨化）。男性舌骨弓高（x1）和舌骨高度（x2）值均高于女性（P<0.01）。性别判定分析方程（y）为y=0.438x1+1.042x2-12.979。判别值为-0.272 5，分辨率为88.2%。
根据舌骨的性别特征，舌骨数据可为法医学实践提供帮助。
