The supratrochlear and supraorbital notches and foramina have been studied in 312 adult skulls of known age and sex. Out of them, in males 49.4% had bilateral supraorbital notches and 13.5% had bilateral foramina, 18.91% had a notch on one side and a foramen on the other side. Bilateral supratrochlear notch was present in 5.4% skulls, 9.65% skulls had bilateral supratrochlear canals and 8.49% had unilateral supratrochlear foramina/ notch on one or the other side. In females, 32% had bilateral supraorbital foramina and 30.18% had bilateral supraorbital notches. 37.7% had unilateral foramen/notch. Supratrochlear canal was present in 13.2% skulls on one or the other side. Bilateral notch was present in 2 skulls (3.77%) only. There was a significant difference between the frequency of supraorbital foramina and notches in males whereas there was no significant difference between the two in females. The distances of the notches/foramina from the midline and also from the temporal crest were measured. The distance of the supraorbital and supratrochlear foramen from the supraorbital rim was measured. There was no significant difference between the two genders. Knowledge of the anatomy of the region is important for those doing forehead and brow lift surgery in order to avoid injuring the neurovascular bundles passing through these notches and foramina, hence the gender wise present study. The methods of study and clinical relevance are discussed.
对312具已知年龄和性别的成年颅骨的滑车上切迹和眶上切迹及孔进行了研究。其中，男性中49.4%有双侧眶上切迹，13.5%有双侧眶上孔，18.91%一侧为切迹另一侧为孔。5.4%的颅骨有双侧滑车上切迹，9.65%的颅骨有双侧滑车上管，8.49%的颅骨一侧或另一侧有单侧滑车上孔/切迹。女性中，32%有双侧眶上孔，30.18%有双侧眶上切迹。37.7%有单侧孔/切迹。滑车上管在一侧或另一侧出现在13.2%的颅骨中。仅2具颅骨（3.77%）有双侧切迹。男性眶上孔和切迹的出现频率之间存在显著差异，而女性两者之间无显著差异。测量了切迹/孔距中线以及距颞嵴的距离。测量了眶上孔和滑车上孔距眶上缘的距离。两性之间无显著差异。了解该区域的解剖结构对于进行额部和眉部提升手术的人很重要，以便避免损伤通过这些切迹和孔的神经血管束，因此进行了本次按性别分类的研究。讨论了研究方法和临床相关性。
