[Efficacy of semicircular canal occlusion in the treatment of fifteen pateints with Meniere's disease].

Objective

To investigate the long-term efficacy of semicircular canal occlusion in the treatment of refractory Meniere's disease. Method:Fifteen patients with Meniere's disease who underwent semicircular canal occlusion were reviewed. The preoperative and postoperative frequency of vertigo ,quality of life, hearing and tinnitus level were compared. All patients were followed for more than 24 months. Result:Postoperatively, vertigo was controlled effectively in all 15 cases, and the control rate was 100%, of which 11 cases were completely controlled（Grade A） and 4 cases were basically controlled（Grade B）. The improvement rate of quality of life was 100%. The hearing worse in 4 cases（26.7%） and stabilized in 11 cases（73.3%）. The tinnitus was relieved in 7 cases（46.7%）, unchanged in 7 cases（46.7%） and aggravated in 1 case（6.7%）.

Conclusion

Semicircular canal occlusion can effectively control the vertigo symptoms of refractory Meniere's disease and improve the quality of life. The long-term efficacy of semicircular canal occlusion is definite, but there is a risk of hearing loss.
