目的：为经海绵窦外侧壁的直接手术提供显微解剖基础。方法：收集４８侧成人新鲜海绵窦标本，在手术显微镜下解剖观测。结果：海绵窦的外侧壁由表层和深层构成，在３１．３％的标本中，两层之间有表腔出现。表腔主要位于Ｐａｒｋｉｎｓｏｎ′ｓ三角内，其形成与大脑中浅静脉（ＣＭＳＶ）的注入有关，它有三个特征可做为经外侧壁手术时的识别标志，既有ＣＭＳＶ注入、表面硬膜较其它部位颜色暗和有散在、粗大的纤维覆盖。本文测量的Ｐａｒｋｉｎｓｏｎ′ｓ三角的大小为９．８ｍｍ×１０．３ｍｍ×４．２ｍｍ，内有颈内部动脉分支走行。Ｍｕｌａｎ′ｓ三角的大小为１０．７ｍｍ×９．５ｍｍ×５．８ｍｍ。结论：了解外侧壁的显微解剖对经外侧壁的手术有临床指导意义。
OBJECTIVE: To provide a microdissection basis for direct surgery of the cavernous sinus lateral wall. Methods: 48 adult fresh cavernous sinus specimens were collected and dissected under a surgical microscope. RESULTS: The outer wall of cavernous sinus consisted of superficial and deep layers, and in 31.3% of the specimens, there was a surface cavity between the two layers. The surface is mainly located in the Parkinson’s triangle. Its formation is related to the injection of superficial cerebral venous superficial veins (CMSV). It has three characteristics that can be used as the identification mark when the lateral wall is operated. Both CMSV injection and epidural Parts of the dark color and scattered, thick fiber cover. The size of the Parkinson’s triangle measured in this paper is 9.8mm × 10.3mm × 4.2mm, with internal branches of the internal carotid artery running. The Mulan’s triangle has a size of 10.7 mm × 9.5 mm × 5.8 mm. Conclusions: Understanding the anatomy of the lateral wall is clinically instructive for surgery of the lateral wall.
