耳蜗透析的基本原理是应用高渗溶液灌注鼓阶,减轻内淋巴水肿。将1.31g甘露醇加入5％葡萄糖溶液至100ml时,即可制得透析液,消毒后备用。该透析液渗透浓度为350毫渗量/升,与蜗管内淋巴的300毫渗量/升相比,是高渗溶液。作者报道自1981～1986年采用此法治疗重度单侧Meniere病30例,疾病严重程度在术前可用250Hz～3KHz纯音听阈检查来估计,听阈大于70dB者20例,介于40～70dB者9例,仅1例为40dB。男13例、女17例。眩晕症状持续3～40年,平均10.5年。手术期年龄28～80岁,平均49.5岁。全部病例经各种内科治疗均
The basic principle of cochlear dialysis is the application of hypertonic solution perfusion scala tympani, reduce endolymphatic edema. When 1.31g mannitol is added into 5% dextrose solution to 100ml, the dialysate can be prepared and disinfected. The dialysate infiltration concentration of 350 ml osmosis / liter, compared with 300 ml osmole / liter of the endolymphatic scroll, is a hypertonic solution. The authors report from 1981 to 1986 using this method in the treatment of severe unilateral Meniere’s disease in 30 cases, the severity of the disease can be preoperative 250Hz ~ 3KHz pure tone audiometry to estimate the hearing threshold greater than 70dB were 20 cases, 40 to 70dB in 9 cases , Only 1 case was 40dB. 13 males and 17 females. Vertigo symptoms persist for 3 to 40 years, an average of 10.5 years. Surgery age 28 to 80 years, mean 49.5 years old. All cases by a variety of medical treatment are
