岩斜区位于颞骨岩部背面与枕骨斜坡部的岩斜裂汇合处,从岩骨尖至颈静脉孔。内侧至斜坡中线,外侧至第Ⅴ、Ⅶ和Ⅷ脑神经,上缘为鞍背,下缘为颈静脉孔水平;下方为枕骨大孔区[1]。岩斜区脑膜瘤由于位置深,毗邻重要解剖结构,很难实现肿瘤全切除,且有较高的术后致残率,一直是神经外科手术 The petroclival zone is located at the confluence of the petroclival fractures on the back of the petrous bone and the occipital slope, from the petrous apex to the jugular foramen. Medial to the slope of the midline, lateral to the Ⅴ, Ⅶ and Ⅷ cranial nerves, the upper edge of the saddle back, the lower edge of the jugular foramen; below the foramen magnum [1]. Due to its deep location and adjacent important anatomical structures, lithotactic meningioma is difficult to achieve complete tumor resection and has a high rate of postoperative disability, and has been a neurosurgery operation
