[摘要]目的：为临床脑桥小脑三角区的手术提供岩静脉的应用解剖学资料。方法：应用26例经10%甲醛充分固定并灌有乳胶的国人成人头颅湿标本，手术显微镜下解剖观察岩静脉的形态、行径及其与三叉神经的毗邻关系。结果：①岩静脉有1～3支，长度(2.9±2.0) mm，外径(2.3±1.0) mm；②岩静脉位于三叉神经根背外方者占92.5%，岩静脉与神经根的最短距离为(5.0±3.8) mm，最长距离为(7.1±4.1) mm，静脉对神经根有压迫的占15.4%；③岩静脉距横窦与乙状窦交角处的距离为(31.1±5.2) mm。结论：岩静脉解剖结构存在许多变异，与三叉神经根关系密切，变异的岩静脉可引起三叉神经痛，手术中应明确岩静脉解剖，避免并发症的发生。

[Abstrct]Objective:To provide anatomical basis of petrosal vein for operation within cellelumpontine angle.Methods:The morphology,course and syntopy of petrosal vein were studied on 26 adult head specimens.Results:①The number of petrosal veinswas between 1 and 3,(2.9±2.0) mm in length and (2.3±1.0) mm in diameter.②The petrosal vein was mostly(92.5%) dorsolateral to the trigeminal nerve root,15.4% of them compressed the nerve root.The distance between the vein and the nerve root renged from (5 ......
