摘要
目的观测岩斜区神经、血管的解剖关系。方法分别从乙状窦后和乙状窦前入路对10例头颅标本进行解剖观测。结果Meckel腔容纳三叉神经节和三叉神经池,其开口宽度为(8.3±1.2)mm,高度为(5.0±1.0)mm。动眼神经、滑车神经、三叉神经、展神经、面神经脑池段长度分别为(18.8±2.8)mm、(35.9±3.1)mm、(12.8±1.7)mm、(17.5±1.9)mm、(13.2±2.2)mm。滑车神经穿入小脑幕游离缘距动眼神经约5.4mm(4.2～6.8mm)。岩下窦位于Ⅸ、Ⅹ脑神经间14侧,Ⅹ与Ⅺ间2侧,在Ⅸ前方汇入颈静脉球或颈内静脉4侧。结论岩斜区神经、血管结构复杂,熟悉此区域的解剖关系,有助于提高岩斜区手术对脑神经与血管的保护,减少并发症。
Objective To observe and measure the anatomical relationship of nerves and arteries to adjacent structures in the petroclival region. Methods The nerves and arteries were anatomized and measured under microscope via retrosigmoid and presigmoid approaches for their distribution, course and anatomical relationship to adjacent structures in 10 cadaveric specimens (20 sides). Results Meckel cave contained the trigeminal ganglion and trigeminal cistern, and the width and height of the cave s opening were 8.3±1.2...
