摘　　要：近年来采用扩大枕下入路切除20例大型听神经瘤，全切率90％，面神经保存率60％。总结了该方法的优，点：①比常规显露向外上扩大位移l～2cm；②小脑半球的缓冲空间增大避免了对脑干的压迫和对小脑半球外1／4的切除；③显露良好使牵拉减少，术中侵袭减小，术后功能恢复较快。同时强调国手术期的处理也至关重要。作者认为：扩大枕下入路范围虽大，但目的是显露良好，减少对脑、神经的牵拉和损伤，最大限度减少并发症．促进康复。This paper reported 20 eases of huge acoustic nurinomathat operated by enlarging unilateral retrosigmoid approach.The total removial tate was 90% and the rate of facial nervepreservation was 60%. This paper described their experi-ences and dominance of the enlarging exposure and mierosur-gical excision: 1. Enlarging exposure takes field of operationenlarging 1～2 cm toward up and outside. 2 Cerebellarhemiphere toward down and outside ,protection brain stemfrom compression and 1/4 cerebellar hemiphere form re-moved .3. So good exposure that retract and invasion weredecreased. Authors described their experiences of total tumorremovial and facial nerve preservation and suggested that goodexposure decreased injury of cranial nerves, cerebellarhemiphere or brain stem, although enlargiag unilateral ret-rosigmoid approach increased field of operation .Facial nervefunction preservation was important too.
