To investigate the anatomic characteristics of Liliequist's membrane.
Liliequist's membrane was studied in eight adult human cadavers under the microscope.
Liliequist's membrane gives rise to three separate arachnoidal sheets: the diencephalic leaf, the mesencephalic leaf, the diencephalic-mesencephalic leaf. The superior margin of the diencephalic leaf between the inferolateral border of the optic tracts and the temporal unci is free. The posterior margin of the diencephalic-mesencephalic leaf is free. The diencephalic leaf and the mesencephalic leaf attach laterally to the mesial temporal surfaces. Liliequist's membrane attaches closely to the hypothalamus. The diencephalic leaf is an accurate landmark which divides the cisterns of the skull base into two groups: pre-Liliequist group and post-Liliequist group. Liliequist's membrane should be opened sharply in order to avoid the injuries to the hypothalamus by blunt operations. In a pterion approach the diencephalic leaf of Liliequist's membrane can be determined according to the relationship with the posterior communicating artery.
Liliequist's membrane is an important landmark for the operations in the sellar area or skull base. Understanding the microanatomy of Liliequist's membrane may be helpful for us to improve the exposure and minimize the injuries during the operations.
研究 Liliequist 膜的解剖学特征。
在显微镜下对 8 具成年人类尸体的 Liliequist 膜进行研究。
Liliequist 膜产生三个独立的蛛网膜片：间脑叶、中脑叶、间脑 - 中脑叶。间脑叶的上缘在视束下外侧缘与颞叶钩回之间是游离的。间脑 - 中脑叶的后缘是游离的。间脑叶和中脑叶在外侧附着于颞叶内侧表面。Liliequist 膜紧密附着于下丘脑。间脑叶是一个精确的标志，将颅底脑池分为两组：Liliequist 膜前组和 Liliequist 膜后组。Liliequist 膜应锐性打开，以避免钝性操作损伤下丘脑。在翼点入路中，可根据 Liliequist 膜间脑叶与后交通动脉的关系来确定。
Liliequist 膜是鞍区或颅底手术的重要标志。了解 Liliequist 膜的显微解剖结构可能有助于我们在手术中改善显露并将损伤降至最低。
