The anterior clinoid process and the optic strut are often removed during operation on the anterior part of the cavernous sinus. Therefore it is important for neurosurgeons to verify their dimensions and variations. The purpose of this study was to investigate the dimension and the variation of the anterior clinoid process and to describe the locational variation of the optic strut. Seventy-three skulls of Korean adults were used. The average length, basal width and thickness of the anterior clinoid process were 9.18 +/- 1.55, 9.63 +/- 1.49 and 5.32 +/- 1.07 mm, respectively. The average thickness of the optic strut was 2.9 +/- 1.15 mm and it was commonly attached to anterior two-fifths of the anterior clinoid process. The complete caroticoclinoid canal was observed in 4.1%, however it was incomplete in 11.6%. The incidence of a caroticoclinoid canal in Koreans was relatively low compared with other races.
在海绵窦前部手术中，前床突和视神经管柱常被切除。因此，神经外科医生了解它们的尺寸和变异情况很重要。本研究的目的是调查前床突的尺寸和变异，并描述视神经管柱的位置变异。使用了73个韩国成年人的颅骨。前床突的平均长度、基底宽度和厚度分别为9.18±1.55、9.63±1.49和5.32±1.07毫米。视神经管柱的平均厚度为2.9±1.15毫米，通常附着在前床突的前五分之二处。观察到完整的颈动脉床突管的比例为4.1%，然而不完整的比例为11.6%。与其他种族相比，韩国人颈动脉床突管的发生率相对较低。
