岩斜区肿瘤以脑膜瘤最为常见,良性居多,手术切除被认为是最理想的治疗手段。由于岩斜区肿瘤深居后颅窝中央,临近脑干及许多神经血管等重要结构,解剖结构复杂,手术暴露困难,目前仍有“不可接近区”之称;术后病死率、伤残率以及复发率均相当高,因此,该区手术极具挑战性,一直是神经外科领域公认的难题之一。20世纪70年代以前,该区 Petroclival tumors with meningioma the most common, mostly benign, surgical resection is considered the best treatment. Because of petroclival tumors deep in the posterior fossa, near the brain stem and many other important neurovascular structures, anatomical structure, surgical exposure is difficult, there are still “not accessible zone”; postoperative mortality, injuries The residual rate and the recurrence rate are quite high, therefore, the operation of the district is extremely challenging, has been recognized as one of the problems in the field of neurosurgery. Before the 1970s, the district
