应仔细检查颞骨岩面，也称为岩锥，以了解该区域脑膜瘤的位置、血供和静脉引流(后颅窝脑膜瘤的42%-59%)。岩面位于蝶骨和枕骨之间的颅底。它由一个侧面连接乳突的底部和一个向前内侧延伸以形成破裂孔的顶点组成。解剖结构可分为三个表面：前/上、后和下。前/上表面是颅中窝后内侧部分的延续，其边界从弧形隆起延伸到岩尖。后表面是以内耳道为中心的后颅窝前部的延续。下表面含有传递重要血管和脑神经的孔。还描述了岩面的血管解剖，包括颈动脉和椎基底动脉系统的分支。了解颅内外动脉之间潜在的吻合途径以及脑神经的动脉供应，有助于术前经动脉栓塞术治疗脑膜瘤，避免术中神经系统并发症的发生。
The anatomy of the petrous face of the temporal bone, also known as the petrous pyramid, should be carefully examined to understand the location of, blood supply to, and venous drainage of meningiomas in this area (42%-59% of posterior fossa meningiomas). The petrous face is located in the skull base between the sphenoid and occipital bones. It consists of a base that joins the mastoid laterally and an apex that extends anteromedially to form the foramen lacerum. The anatomy can be divided into three surfaces: anterior/superior, posterior, and inferior. The anterior/superior surface is a continuation of the posteromedial portion of the middle cranial fossa with boundaries extending from the arcuate eminence to the petrous apex. The posterior surface is a continuation of the front part of the posterior cranial fossa with the internal auditory meatus at its center. The inferior surface contains foramina that transmit important vessels and cranial nerves. The vascular anatomy of the petrous face is also described, including branches of the carotid artery and vertebrobasilar systems. It is imperative to understand potential anastomotic routes between extracranial and intracranial arteries, as well as arterial supply to cranial nerves, to facilitate preoperative transarterial embolization of meningiomas and avoid neurologic complications during surgery.
