Results: The ventral surface of abducent nerve root was crossed by anterior inferior cerebellar artery, inferolateral pontine artery, posterior inferior cerebellar artery, labyrinthine artery, common trunk of posterior and anterior inferior cerebellar artery and vertebral artery; 结果:从展神经根腹面跨过的有小脑下前动脉、脑桥下外侧动脉、小脑下后动脉、迷路动脉、小脑下后和小脑下前动脉总干、椎动脉;
Results: Cerebellopontine segment and interauricular canal segment of the facial nerve were supplied by cerebellar inferior anterior artery ( labyrinthine artery); 结果:面神经小脑脑桥角段、内耳道段主要由小脑下前动脉发出的迷路动脉供应;
Results: Anterior inferior cerebellar artery ( AICA) was constantly present in all specimens ( 100%), the incidence of labyrinthine artery ( LA), recurrent perforating artery ( RPA) and subarcuate artery ( SA) was 100%, 90.0%, 13.3% respectively. 结果:小脑前下动脉出现率为100%,其中分支迷路动脉、回返穿通动脉、弓状下动脉的出现率分别为100%、90.0%、13.3%。
Labyrinthine segment of the facial nerve was supplied by petrous branch of middle meningeal artery; 面神经迷路段由脑膜中动脉发出的岩浅支供应;
