200例国人眼眶外侧沟及相关结构的观察

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。

A GROOVE IN THE LATERAL WALL OF ORBIT IN 200 CHINESE

A groove in the laternal wall of the human orbit was found in 77/200orbits (38.5±3.4%).the orbital groove probably lodyes an anastomosis between middle meningeal and infraorbital blood vessles.The foramen meningo-orbitale(FMO),which was found in 66/200 orbits(33.0±3.3%),is just situated laterally to the lateral extremity of the superior orbitalfissure(SOF).The groove of the orbital branch of the middle meningeal artery is presentin 82/100(82.0±3.8%).It passes to the SOF or to the FMO.
