本文观察了２００例成人骨眶，发现有眶外侧沟７７例（３８．５±３．４％），此沟提示脑膜中动脉的眶支与眶下动脉的吻合所在。脑膜眶孔的出现率为３３．０±３．３％，此孔的局部位置在眶上裂外侧端外侧的邻近部位。脑膜中动脉的眶支沟的出现率为８２．０±３．８％．此沟延至眶上裂或脑膜眶孔。
In this paper, we observed the bony orbit of 200 adults and found that there were 77 cases (38.5 ± 3.4%) of the lateral orbital groove. This groove suggested the anastomosis between the orbital branch of the middle meningeal artery and the infraorbital artery. The incidence of the orbital foramen of the meninges was 33.0 ± 3.3%, and the local location of this hole was adjacent to the lateral part of the lateral superior orbital fissure. The incidence of the orbital branch of the middle meningeal artery was 82.0 ± 3.8%. This ditch extends to the superior orbital fissure or the meningeal orifice.
