The aim of the study was to examine the different anatomical variations of the supraorbital, infraorbital, and mental foramina related to gender and side.
Measurements were made on 110 adult skulls without mandibles and isolated mandibles. Gender was determined for each skull. Parameters measured bilaterally included the distances from the supraorbital and mental foramina to midline, from the infraorbital foramen to the anterior nasal spine, from the infraorbital foramen to the inferior orbital rim, and from the mental foramen to the inferior rim of the mandible and the angle between the line linking the infraorbital foramen with the anterior nasal spine and horizontal plane. Comparisons were made between genders and sides and statistical analysis was done where appropriate using Student's t test.
There were 70 male and 40 female crania. Nature of the 3 foramina was similar between sides and genders. The average distance from the left supraorbital foramen to midline in females was significantly lower than that in males (2.42+/-0.04 versus 2.56+/-0.05). The mean distances from the bilateral infraorbital foramina to anterior nasal spine in females were also significantly lower relative to those in males (3.28+/-0.03 versus 3.48+/-0.03 right and 3.31+/-0.03 versus 3.50+/-0.03 left). There were also considerable differences between sides in the average angle of the infraorbital foramen in both genders.
Differences in several measurements suggest that gender and side should be considered when applying the anatomical variation data to an individual subject.
本研究旨在探讨眶上孔、眶下孔和颏孔与性别及左右侧相关的不同解剖变异。
对110例无下颌骨的成人颅骨及分离的下颌骨进行测量。确定每个颅骨的性别。双侧测量的参数包括眶上孔和颏孔到中线的距离、眶下孔到前鼻棘的距离、眶下孔到眶下缘的距离、颏孔到下颌骨下缘的距离，以及连接眶下孔与前鼻棘的线与水平面的夹角。对性别和左右侧进行比较，并在适当情况下使用学生t检验进行统计分析。
有70例男性颅骨和40例女性颅骨。两侧和两性之间3个孔的性质相似。女性左侧眶上孔到中线的平均距离显著低于男性（2.42±0.04对2.56±0.05）。女性双侧眶下孔到前鼻棘的平均距离相对于男性也显著更低（右侧3.28±0.03对3.48±0.03，左侧3.31±0.03对3.50±0.03）。两性眶下孔平均角度在左右侧之间也存在显著差异。
多项测量结果的差异表明，在将解剖变异数据应用于个体时应考虑性别和左右侧因素。
