斜坡位于后颅底中线区,位置深在,毗邻脑干、颈内动脉、第Ⅴ~Ⅻ对脑神经、海绵窦等重要结构,该区手术一直是神经外科的难题。随着近年来对颅底解剖的进一步了解,该区域病变的手术也取得了较大进步。本文重点综述四类经前方手术入路的解剖与手术技术。1斜坡的解剖1.1毗邻及分部斜 The slope is located in the midline of the posterior cranial base, deep in the location, adjacent to the brain stem and internal carotid artery. The Ⅴ ~ Ⅻ are important structures such as cranial nerves and cavernous sinus. Surgical operation has been a difficult problem in neurosurgery. With the further understanding of skull base anatomy in recent years, the surgery of lesions in the region has also made great progress. This article focuses on four types of anterior approach to anatomy and surgical techniques. Anatomy of the Slopes 1.1 Adjacent and Branch Oblique
