【摘要】 目的:总结35例听神经瘤显微手术切除经验,为进一步提高肿瘤全切除和面、听神经保留率,预防并发症。方法:对35例听神经瘤采用枕下—乙状窦入路显微手术切除,并对手术要点、肿瘤大小与肿瘤全切率和面、听神经保留率之间的关系进行讨论。结果:6例小于2cm的肿瘤全部全切除,18例2~4cm肿瘤,全切14例,11例大于4cm的肿瘤,仅5例全切。肿瘤全切率为71.4%(25/35),面神经解剖保留率65.7%(23/35),功能保留率57.1%(20/35),术后无死亡病例。结论:肿瘤大小与肿瘤全切率及面听神经保留率密切相关,熟练掌握显微手术技巧,可提高面神经保留功能。更多还原

【Abstract】 Objective: To summarize the clinical experience of microsurgical operation of acoustic neuromas and increase the complete resection rate of of acoustic neuromas and the preservation rate of facial nerve functionand and auditory nerve function,prevent the complications.Method: All the 35 cases with acoustic neuromas underwent operation through suboccipital approach.The relationship of the tumor size and the rate of complete resection of the acoustic neuromas,preservation rate of facial nerve function and and auditory nerve function and operative points were discussed.Result: 6 cases with acoustic neuromas sized less than 2cm were resected completely.14 of the 18 cases with acoustic neuromas sized 2～4cm were resected completely.Only 5 of the l l cases with acoustic neuromas sized larger than 4cm were resected completely.The complete resective rate of acoustic neuromas were 71.4%.The anatomy preservation rate of facial nerve function is 65.7%and the functional preservation rate of facial nerve is 57.1%.None of cases died.Conclusion: The rate of complete resection of the acoustic neuromas and the preservation of the facial nerve function,auditory nerve function depends on the size of the acoustic neuromas.Mastering the microsurgical skill can help to increase the preservation rate of facial nerve function.更多还原
