面神经根与邻近血管的关系

Relationship between the facial nerve root and its surrounding vessels

目的 观测面神经根与邻近血管的关系。方法 解剖和观测 4 9侧面神经根与邻近血管间的关系。结果 面神经根受邻近血管压迫的占 2 4 5 % (12 / 4 9) ,与邻近血管发生接触的占 14 3%(7/ 4 9)。压迫和接触面神经根的主要血管为小脑下前动脉 (AICA) ,其次是小脑下后动脉 (PICA) ,移位的椎动脉 (VA)和小脑下前静脉。

Objective To study relationship between facial nerve root and its surrounding vessels. Methods 49 sides facial nerve root and its surrounding vessel were dissected and observed. Results Facial nerve root and its surrounding vessels forming compression was found to be 24.5%(12/49),creating contact was found to be 14 3%(7/49). The main vessels compressed or (and) contacted facial nerve root were anterioinferior cerebellar artery(68 4%),posterioinferior cerebellar artery (4 1%), malformed vertebral artery(4 1%) and anterioinferior cerebellar vein. Conclusions Facial nerve root compressed by offending vesselsare was mainly cause of hemifacial spasm.
