Abstract

Background: Determination of gender using skeletal remains presents a great problem to forensic experts. Among many anatomical landmarks in human skull, the mental foramen (MF) is a stable landmark. Objectives: To estimate gender of individuals by radiographic analysis of MF on computed tomography. Methods: A retrospective study was performed on 100 computed tomography images of patients. The sample was chosen in 1:1 ratio with 50 males and 50 females. Digital scale was used in computed tomography images for marking the tangents on superior and inferior border of MF and perpendiculars were drawn from tangents to lower border of mandible bilaterally and measurements were recorded. Results: The mean distance from the superior border of the MF to the lower border of the mandible and the inferior border of the MF to the lower border of the mandible on right and left sides was more in males when compared to females, which was statistically significant. Conclusion: The distances from the MF to the lower border of the mandible exhibit sexual dimorphism. This method is efficient and can be considered as an additional radiographic method to determine gender from skeletal remains.

计算机断层扫描中对脑孔的放射分析测定性别

背景:使用骨骼遗骸确定性别对法医专家来说是一个很大的问题。在人类颅骨的众多解剖标志中，颏孔(MF)是一个稳定的标志。目的:通过计算机断层扫描上MF的放射学分析来估计个体的性别。方法:对100例患者的计算机断层图像进行回顾性研究。样本按1:1的比例选择，男女各50人。计算机断层图像采用数字比例尺标记下颌上下缘切线，并在两侧下颌骨切线与下缘之间画垂线，记录测量结果。结果:右、左两侧MF上缘到下颌骨下缘、MF下缘到下颌骨下缘的平均距离男性大于女性，差异有统计学意义。结论:下颌中颞下颌缘到下颌下缘的距离呈现两性二态性。这种方法是有效的，可以被认为是一种额外的射线摄影方法来确定骨骼遗骸的性别。
