摘　　要：目的 为了在前庭蜗神经瘤(VN)手术中提高面神经和前庭蜗神经功能保留率。方法 在手术显微镜下观察了52例前庭蜗神经瘤病人的桥脑小脑角(CPA)解剖结构及VN与周围神经、血管的解剖关系。结果 在VN包膜外两层蛛网膜间粘连最少,容易解剖分离,有利于术中保留面、前庭蜗神经功能。结论 在手术显微镜下能更清晰地辨清VN周围的解剖关系,有助于减少而、前庭蜗神经的损伤。Objective To increase the chance of keeping the facial and vestibulocochlearis nerves from being damaged in vestibulocochlearis neurinomas (VN) operations. Methods We observed under a microscope the anatomic construction of the cerebellopontine angle(CPA) and the anatomtic relations of VN with its surrounding nerves and vessels. Results There are two layers of arachnoid on the surface of VN. They are not firmly bond with each other and thus can be easily separeted in the operation. In this way, the facial and vestibulocochlearis nerves can be kept from being damaged. Conclusion We can see rather clearly the anatomic relations of VN and its surrounding organizations under a microscope. This helps reduce the chance of damaging the facial and vestibulocochlearis nerves.
