摘　　要：目的总结面听神经根压迫综合征48例的手术治疗经验,并对病因进行探讨。方法经乙状窦后入路进入桥小脑角区,在手术显微镜下对面听神经根及周围进行仔细检查,寻找病因,对相关病灶给予相应微血管减压、粘连分解及面神经梳理等处理。结果术中发现48例面听神经根均有责任血管压迫,其中16例伴有明显的蛛网膜增厚、粘连。术后全部病例均痊愈出院。随访1～15年,有2例耳鸣症状复发,4例面肌痉挛症状复发,但均较术前轻,无耳聋者。结论面听神经压迫综合征48例,其致病因素以责任血管压迫为主,部分伴有蛛网膜粘连。Objective To summarize the 48 reports of the patients with auditory and cranial nerve root compression and research the causes of the disease.Methods Cerebellopontine angle was reached via retrosigmoid approach.The auditory and cranial nerve root was carefully checked so that the causes could be found.Microvascular decompression（MVD）,adherence splitting and cranial nerve combing were performed to different niduses under microscope.Results The auditory and cranial nerve roots were found to be oppressed by primary blood vessels in all the patients,16 of whom were accompanied with arachnoid thickening and adhesion.All the patients were operated successfully and discharged.Tinnitus recurred in two patients and mimetic convulsion recurred in four ones according to 1-15 years,follow-up,but they were ameliorated after operation.Conclusion The main etiological factor of auditory and cranial nerve compression syndrome is oppression of primary blood vessel as to the 48 patients.Some ones suffer from additional arachnoid thickening and adhesion.
