目的：探讨不同视角下视神经-颈内动脉间隙的显微解剖，不同角度下其内的重要结构的显示。方法7成人湿性头颅标本模拟翼点入路双侧开颅，应用手术显微镜沿颅底方向在不同手术视角(0°、30°、60°)下对视神经-颈内动脉间隙进行观察。结果视神经-颈内动脉间隙多呈三角形，随视角由0°~60°，间隙内容物发生改变，其中30°时，显露面积最大，结论在30°视角下颈内动脉间隙的可应用空间最大，视神经-颈内动脉间隙的形态、面积、构型是由颈内动脉分叉高低及颈内动脉是否迂曲决定的。

Objecttive To observe the microanatomy of opticcarotid space through pterional approach and the important structure in the interspaces under different visual angles.Methods Microsurgical anatomy of 14 opticocarotid space through the pterional approach was observed at 3 operational angles (0 °、30 °、60 ° )using 7 cadeveric heads.Results The opticocarotid space shape looked like tringle.The important structure had changed under operational angles.The areas of opticocarotid space was biggest under angle 30°。Conclusions The operating space of opticocarotid space is biggest used under 30°。The sharp、area and the structure of the opticocarotid space depend on the position of the internal carotid artery bifurcation and the tortuous internal carotid artery whether or not.
