Sex determination in unidentified skeletons is not always easily and correctly performed by a non-specialist without formal training in forensic anthropology. In explosions, warfare and other mass disasters like aircraft crashes, identification may be extremely complicated because of skeletal fragmentation. The aim of the present study was to determine whether the area of the foramen magnum was a useful criterion for the sex determination in fragmented skulls. In a total of 219 skeletons (170 males and 39 females) the longest and the shortest diameter of the foramen magnum was measured; the area within was determined using the mean of the diameters as the radius for calculation. The mean of foramen magnum area was significantly different (909.91 +/- 126.02 mm2 in males, 819.01 +/- 117.24 mm2 in females homogeneous variance, Student's t-test: 4.11 P< 0.001). However, the correlation coefficient between the areas of foramen magnum and sex was 0.27. The results confirmed that the mean foramen magnum area in females is lower than in males. However, the area of foramen magnum is not a very useful indicator for sex identification and can be used only under some circumstances as a supportive finding.
对于未经法医人类学正规培训的非专业人员而言，确定不明身份骨骼的性别并非总是轻而易举且准确无误。在爆炸、战争以及飞机坠毁等其他大规模灾难中，由于骨骼破碎，身份识别可能极其复杂。本研究的目的是确定枕骨大孔面积是否是判定破碎头骨性别的有用标准。在总共219具骨骼（170具男性和39具女性）中，测量了枕骨大孔的最长和最短直径；通过将直径的平均值作为半径来计算内部面积。枕骨大孔面积的平均值存在显著差异（男性为909.91 +/- 126.02平方毫米，女性为819.01 +/- 117.24平方毫米，方差齐性，学生t检验：4.11，P < 0.001）。然而，枕骨大孔面积与性别之间的相关系数为0.27。结果证实，女性枕骨大孔的平均面积低于男性。然而，枕骨大孔面积并非性别识别的非常有用的指标，仅在某些情况下可作为辅助发现使用。
