迷路功能障碍所致眩晕有多种有效的手术方法,对尚有可用听力者,可采用前庭神经切断术(RVNS)。据报告RVNS对梅尼埃病疗效良好,而对非梅尼埃病疗效较差。作者报道一组病例并评价非梅尼埃病RVNS的疗效。 90例药物治疗无效致残性眩晕患者接受RVNS,男43例,女47例,年龄14～66岁,平均42岁。梅尼埃病48例(53%),失代偿性前庭神经炎(UVN)(组Ⅰ)23例(26%),余19例(21%)为各种原因所致迷路功能障碍:又分为伴单侧感音神经性聋(SNHL)或一耳化脓感染8例(组Ⅱ),伴对称性SNHL11例(组Ⅲ)。术前术后均作听力、耳蜗电图、前
Dizziness caused by labyrinthine dysfunction There are a variety of effective surgical methods, there are still available hearing available vestibular nerve resection (RVNS). RVNS is reported to be effective in treating Meniere’s disease and less effective in managing non-Meniere’s disease. The authors reported a group of patients and evaluated the efficacy of non-Meniere’s disease RVNS. Ninety-eight patients (47 males and 47 females, aged 14-66 years, mean 42 years) received RVNS in 90 patients with disabling dizziness. There were 48 cases of Meniere’s disease (53%), 23 cases (26%) of decompensated vestibular neuritis (Group I), and 19 cases (21%) of them were caused by various causes of dysfunction: Divided into unilateral sensory nerve deafness (SNHL) or purulent ear infection in 8 cases (group Ⅱ), with symmetry SNHL11 cases (group Ⅲ).
