目的:探讨在内淋巴囊减压的基础上同时行外、后半规管阻塞治疗顽固性梅尼埃病的外科技术。方法:选择33例中晚期梅尼埃病患者,均在全身麻醉下完成内淋巴减压,同时磨开外、后半规管骨质,以软组织填塞外后半规管管腔。结果:所有患者均顺利完成手术,术后无面瘫、全聋及新生耳鸣发生;所有患者均有头朦胧感、不平衡感,其中术后1周内6例语言频率骨导听力下降,1例术后2个月发生突发性听力下降伴旋转性眩晕直至全聋。结论:该研究设计的理论基于减轻内淋巴积水压力与对传导通路的控制,在切除内淋巴囊表面骨质的基础上同时行外、后半规管阻塞,外科技术较易掌握。
OBJECTIVE: To investigate the surgical techniques for the treatment of intractable Meniere’s disease with occlusion of the posterior semicircular canal at the same time based on the decompression of the endolymphatic sac. Methods: Thirty-three patients with mid-late stage Meniere’s disease were selected and underwent endolymphatic decompression under general anesthesia. At the same time, the external semicircular canal was opened and the semicircular canal was filled with soft tissue. Results: All patients were successfully completed surgery without postoperative facial paralysis, total deafness and neonatal tinnitus occurred; all patients have head haze, imbalance, including 1 case within 6 weeks after the frequency of bone conduction hearing decreased, 1 case Sudden hearing loss after 2 months with rotational dizziness until total deafness. Conclusion: The theory of this study is based on the reduction of endolymphatic hydrops pressure and the control of the conduction path. In addition to the removal of the surface of the endolymphatic sac, the theory of the study is designed to be performed simultaneously with the occlusion of the posterior semicircular canal.
