摘要
目的探讨前庭神经及部分耳蜗神经切断术治疗梅尼埃病的疗效及方法。方法回顾性分析自1998年8月至2003年3月采用乙状窦后进路内镜下前庭神经切断、部分耳蜗神经切断术治疗的9例梅尼埃病患者的临床资料，随访2，4年，对控制眩晕、耳鸣的疗效及保留听力的情况进行评估。结果9例患者眩晕均完全控制，均出现高频区听力缺失（4000—8000Hz），低频区听力保存。耳鸣改善情况：5例消失，4例减轻，无加重病例。平衡代偿时间：9例术后均出现水平性眼震，持续7～10天，术后走路不稳的代偿时间是15—60天。并发症：1例术后5天发生迟发性面瘫，经药物治疗后40天恢复。结论该术式能有效地控制眩晕、缓解耳鸣，并能保留部分语频区听力，是治疗梅尼埃病的有效方法之一。
Objective To study the effects and methods of the retrosigrnoid endoscope - assisted vestibular nerve section and partial cochlear nerve section for Meniere disease. Methods Since 1998, 9 case of intractable Meniere disease were treated through the operation of retrosigrnoid endoscope - assisted. During the 2 to 4 year follow- up, the patients were monitored for the controlled vertigo and improved tinnitus as well as the heating status. Results All the patients were found to have vertigo controlled and to have hearing loss cross 4 000 - 8 000 Hz, while low - frequency hearing remains intact. Complete relief of tinnitus was achieved in 5 patients, and noticeable improvement was noted in 4 patients. Conclusion Vestibular nerve section and partial cochlear nerve section are the most effective way to treat Meniere disease, especially for the improvement of tinnitus, controlled vertigo and the preservation of heating sensitivity in the speech range.
