The purpose of this study was to locate the constant anatomic landmarks for anterior skull base surgery via endoscopic transnasal approach in Chinese subjects.
Eight cases of adult skull specimens (all Chinese) were dissected by the endoscopic transnasal approach. The relationships of the anatomic landmarks under endoscopic view were characterized. The distance between the columella and the anterior ethmoid artery (AEA) or the posterior ethmoid artery (PEA) was measured.
The uncinate process attached to the lamina papyracea in 7 sides (43.8%), to the skull base in 4 sides (25%), and to the middle turbinate in 3 sides (18.8%). In addition, the uncinate process was found to have bifurcated attachment in 2 sides (12.5%).The mean ± SD distance from the columella to the AEA was 62.71 ± 2.18 mm on the right side and 63.38 ± 1.69 mm on the left side. The mean ± SD distance from the columella to the PEA was 70.91 ± 1.99 mm on the right side and 71.79 ± 1.95 mm on the left side.
The frontal recess, the AEA, and the PEA can serve as the constant landmarks in the transnasal endoscopic approach to the anterior skull base.
本研究旨在确定中国人群中经鼻内镜入路进行前颅底手术的恒定解剖标志。
采用经鼻内镜入路对8例成人颅骨标本（均为中国人）进行解剖。描述内镜视野下解剖标志之间的关系。测量鼻小柱与筛前动脉（AEA）或筛后动脉（PEA）之间的距离。
钩突附着于纸样板7侧（43.8%），附着于颅底4侧（25%），附着于中鼻甲3侧（18.8%）。此外，发现钩突有2侧（12.5%）呈分叉附着。鼻小柱至右侧AEA的平均±标准差距离为62.71±2.18mm，至左侧AEA的平均±标准差距离为63.38±1.69mm。鼻小柱至右侧PEA的平均±标准差距离为70.91±1.99mm，至左侧PEA的平均±标准差距离为71.79±1.95mm。
额隐窝、AEA和PEA可作为经鼻内镜入路前颅底手术的恒定标志。
