目的:探讨半规管阻塞术对3、4期顽固性梅尼埃病的疗效。方法:29例梅尼埃病患者术前听力分期为梅尼埃病3、4期,其中3期12例,4期17例,均行半规管阻塞术。对比分析患者术前与术后眩晕、听力、前庭双温试验、耳鸣分级、功能分级等情况。随访6~23个月,平均13个月。结果:术后眩晕控制率100%,其中26例(89.7%)完全控制,3例(10.3%)基本控制;术后听力无明显变化者25例(86.2%),听力提高2例(6.9%),听力下降2例(6.9%);前庭双温试验示术后术耳半规管功能减弱;术后耳鸣改善12例(41.4%);功能分级下降28例(96.6%)。结论:半规管阻塞术能有效控制3、4期梅尼埃病患者的眩晕发作,短期疗效确切,能有效改善患者生活功能,但长期疗效仍需继续观察。
Objective: To investigate the curative effect of semicircular canal obstruction on refractory Meniere’s disease in stage 3 and 4. Methods: The preoperative listening staging of 29 Meniere’s disease patients was stage 3 and stage 4 of Meniere’s disease, of which 12 cases were in stage 3 and 17 cases were in stage 4, all underwent semicircular canal occlusion. Preoperative and postoperative patients with vertigo, hearing, vestibular dual temperature test, tinnitus classification, functional grading and so on were compared and analyzed. Follow-up 6 to 23 months, an average of 13 months. Results: The control rate of postoperative vertigo was 100%, of which 26 cases (89.7%) were completely controlled and 3 cases (10.3%) were basically controlled. There were 25 cases (86.2%) with hearing improvement and 2 cases (6.9% ), Hearing loss in 2 cases (6.9%). The vestibular double-temperature test showed that the function of the semicircular canal decreased after operation. Tinnitus improved in 12 cases (41.4%) and functional grading decreased in 28 cases (96.6%). Conclusion: The semicircular canal occlusion can effectively control the onset of vertigo in patients with Meniere’s disease of stage 3 and 4, and the short-term curative effect is definite. It can effectively improve the life function of patients, but the long-term curative effect still needs to be observed.
