摘　　要：目的探讨乙状窦后径路选择性前庭神经切断术对梅尼埃病患者听力的影响。方法回顾性研究2006年7月～2008年7月间,6例乙状窦后径路选择性前庭神经切断术治疗的梅尼埃病患者手术前后眩晕发作频率、纯音听阈及前庭功能的改变。结果 6例患者手术前后纯音听阈差异无统计学意义(P>0.05);5例患者术后眩晕完全控制,1例基本控制;2例患者前庭功能完全代偿,4例部分代偿。结论乙状窦后径路选择性前庭神经切断术能有效地控制眩晕,保留或改善患者既有听力,是治疗梅尼埃病的有效方法。Objective To observe the effects of retrosigmoid approach for vestibular neurectomy on heating in patients with Mertiere＇s disease. Methods A retrospective study was carried out. Six patients receiving retrosigmoid approach vestibular neurectomy from July 2006 to July 2008 were involved in this study, and their vertigo attack frequency, pure tone hearing threshold and vestibular function test before and after the surgery were analyzed respectively. Results There was no significant difference in pure tone hearing threshold before and after the surgery （p〉0.05）. After the surgery, 5 cases were found complete vertigo control while 1 case was generally controlled. Vestibular fimetion of 2 cases was completely compensated, and the other 4 cases partly compensated. Conclusion Selective vestibular neurectomy via retrosigmoid approach is one of the most effective methods for the control of vertigo in Meniere＇s disease while preserving or improving the residual hearing.
