本文对200例成人骨性眼眶作了观测,发现有眶外侧沟者70例(35±3.37%).有15个颅的两侧眶同时呈现眶外侧沟(27.27±6.03%).脑膜眶孔的出现率为59±3.48%,此孔位于眶上裂外侧端的外侧,两者之间的距离为0.2～1.8cm.孔的局部位置可位于蝶骨大翼眶面,额骨眶面或蝶骨大翼与额骨眶面的交界处.脑膜中动脉眶支沟的出现率为89±3.12%.此沟有的仅延伸至眶上裂或脑膜眶孔,有的既至眶上裂又至脑膜眶孔.眶外侧沟提示脑膜中动脉与眶下动脉之间吻合的所在.
In this study, 200 adult bony orbital eyes were observed and 70 cases (35 ± 3.37%) had lateral orbital ditch with 15 orbital orbital lateral fissures (27.27 ± 6.03%). The incidence was 59 ± 3.48%, this hole is located outside lateral to the superior orbital fissure, the distance between the two is 0.2 ~ 1.8cm. Locations of the hole can be located in the sphenoid wing orbital, frontal orbital or butterfly Bone big wing and the frontal orbital interface at the junction of the middle meningeal artery orbital branch of the incidence of 89 ± 3.12% .This groove only extends to the supraorbital fissure or meninges orbital foramen, and some even to the superior orbital fissure To the meningeal orbital foramen.The orbital ditch suggests the anastomosis between the middle meningeal artery and the infraorbital artery.
