posterior clinoid process

Methods: The distance and angle between the zygomatic process and anterior and posterior clinoid process of two sides.

方法：测量100例成人颅骨标本额骨颧突距同侧和对侧前后床突的距离和角度；

Results: The oculomotor nerve entered into cavernous sinus at 7.8 ± 2.1 mm anterolateral to posterior clinoid process and 5.0 ± 2.0 mm posterior to superior segment of clinoid process of internal carotid artery.

结果：动眼神经入窦点在后床突的前外侧7.8±2.1mm，在颈内动脉床突上段后方5.0±2.0mm处。

Results: The nerve entered into dura mater 17.0 ± 2.1 mm inferior to the posterior clinoid process.

结果：展神经穿硬脑膜处位于后床突下方17.0±2.1mm。

Dorsum sellae and posterior clinoid process were difficult to reveal because the restriction of pituitary, the superior limits of clival bone removal was sellar floor.

上方因有垂体阻挡，鞍背及后床突显露困难，斜坡骨质开窗上方界限为鞍底。
