Results With orbitozygomatic approach, drilling the anterior clinoid process got a space called the clinoid space. The membrane between the internal carotid artery beneath the anterior clinoid process and the oculomotor nerve is called carotidoculomotor membrane. Along the membrane, the cavernous sinus can be reached. After drilling the posterior clinoid process, exposing the dorsum sellae and the upper clivus, the superior segment of the basilar artery can be exposed.

结果 磨除前床突后形成的间隙为床突间隙；前床突下颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜，沿此膜可进入海绵窦；磨除后床突后，暴露鞍背、上斜坡，即可显露基底动脉上段。
