摘要
前庭神經切斷術是一種有效治療單側周邊前庭病變所引起的反覆發作頑固性眩暈，並且可以保留聽力的手術方式。本文收集自1995年1月至1997年2月間，11例單側梅尼爾氏症患者，因反覆發作眩暈經藥物、飲食及生活減壓治療失敗後，本科採取經乙狀竇後(retrosigmoid)施行前庭神切斷術，術後追蹤時間至少1年(平均17個月)。追蹤期間無1例有眩暈復發，眩暈控制成功率達100%，聽力保留比率達91%。耳鳴改變的情形為術前11例皆有耳鳴現象，但於術後有1例耳鳴完完消失，2例耳鳴改善，其他8例無變化。術後並無憑何嚴重之併發症。我們認為，經乙狀竇後施行前庭神經切斷術是一種治療單側梅尼爾氏症所引起的頑固性眩暈的一種兼具安全、有效且可保留聽力的手術。(中耳醫誌 1997;32:402-407)

Vestibular neurectomy has become a more frequently performed procedure to cure symptoms of inner ear vertigo without scarifying hearing. Between January 1995 and February 1997, 11 retrosigmoid vestibular neurecomies were performed for unilateral Meniere’s disease with intractable vertigo. The cue rate of vertigo is 100% during the follow-up period of 1 year to 2 years and 1 month (mean 17 months). The hearing preservation was achieved in 91% patients. After operation, the symptom of tinnitus disappeared in 1 case, was reduced in 2 cases, and was unchanged in the others. No major complicatin was noted postoperatively. Retrosigmoid vestibular neurectomy is a safe and effective procedure for control of the intractable vertigo in patients with Meniere’s disease without scarifying hearing.
