Abstract: 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+1.042x2-12.979,判别值为-0.2725,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.
