Endolymphatic-mastoid shunt operation due to Kitahara's method was performed on 24 patients with Meniere's disease. In 14 patients, the vertiginous attack was controlled with satisfactory preservation of hearing for longer than one year. In 2 patients, the vertiginous attack subsided but the hearing worsened. In the remaining 8 patients, long-term control of the vertiginous attack was not attained. Of these 8 recurrent cases, revision was performed on 4, revealing shunt obstruction with granulation or scar tissue. After reopening the endolymphatic sac, a large triangular Silastic sheet was placed into its lumen. The vertiginous attack was controlled thus far in the revised cases using this procedure.
采用北原法对24例梅尼埃病患者实施了内淋巴囊-乳突分流术。14例患者的眩晕发作得到控制，听力得以满意保留且持续时间超过一年。2例患者眩晕发作消退，但听力恶化。其余8例患者未实现眩晕发作的长期控制。在这8例复发病例中，对4例进行了翻修手术，发现分流管被肉芽组织或瘢痕组织阻塞。重新打开内淋巴囊后，将一块大的三角形硅橡胶片置入其内腔。采用该方法对翻修病例的眩晕发作进行控制，至今效果良好。
