To study the mandibular angle in Black Zimbabweans so as to assess its role in the anthropological diagnosis of human remains and in laryngoscopy.
The angles, lengths and heights of adult mandibles derived from Black Zimbabwean cadavers were measured using a mandibulometer. The values obtained for these parameters were analysed statistically.

32 adult Black Zimbabweans (23 males and nine females) who had lived in Harare, Zimbabwe.
Sexual differences in the mandibular angle, height, length among Black Zimbabweans.
The mean mandibular angle and height were greater in females (128 degrees and 6.13 cm) than in males (123.06 degrees and 5.98 cm) while the mean mandibular length was greater in males (7.78 cm) than in females (7.23 cm). There was a statistically significant sex difference in the mandibular angle and length. The average mandibular angle of the Black Zimbabweans was greater than the values reported for some Black African populations but the range of variation was small.
It appears that the Black Zimbabwean mandible cannot be used for sexual or racial diagnosis of individuals as is usual in anthropological work. However, the male Black Zimbabwean mandible appears to possess important unfavourable anatomic factors that may predispose the male Black Zimbabwean to difficult laryngoscopy and/or intubation.
研究津巴布韦黑人的下颌角，以评估其在人类遗骸人类学诊断及喉镜检查中的作用。
使用下颌骨测量仪测量来自津巴布韦黑人尸体的成年下颌骨的角度、长度和高度。对这些参数获得的值进行统计学分析。

32名居住在津巴布韦哈拉雷市的成年津巴布韦黑人（23名男性和9名女性）。
津巴布韦黑人下颌角、高度、长度的性别差异。
女性的平均下颌角（128度）和高度（6.13厘米）大于男性（123.06度和5.98厘米），而男性的平均下颌长度（7.78厘米）大于女性（7.23厘米）。下颌角和长度存在统计学上显著的性别差异。津巴布韦黑人的平均下颌角大于一些非洲黑人种群报告的值，但变异范围较小。
似乎津巴布韦黑人的下颌骨不能像人类学工作中通常那样用于个体的性别或种族诊断。然而，津巴布韦黑人男性的下颌骨似乎具有重要的不利解剖因素，这可能使津巴布韦黑人男性更易出现喉镜检查和/或插管困难。
