[The surgical treatment discussion in intractable Meniere's disease: lateral and posterior semicircular canal plugging with endolymphatic sac decompression]

Abstract

Objective:To introduce and discuss a surgical technique, i.e. lateral and posterior semicircular canal plugging with endolymphatic sac decompression, to treat intractable Meniere's disease.Method:Thirty-three cases of intractable Meniere's disease were enrolled. All cases were performed under general anesthesia. The endolymphatic sac was decompressed and the bone of lateral and posterior canal were drilled to create a fenestra followed by soft tissue plugging into the canal.Result:All cases had no facial palsy, no total defness, no vertical after surgery. In the period of following up, the attack of Meniere's disease was completely controlled and the hearing loss happened for 6 case one week after operation. One case had sudden hearing loss with vertical and result of defness.Conclusion:The design of this surgical procedure was based on relieving endolymphatic press and controlling the nerve pulse transmission. The surgical technique was reliable for lateral and posterior semicircular canal plugging with endolymphatic sac decompression.
