在美尼尔氏病患者中,一部分人仍有足够的听力,治疗时要求选用既能解除眩晕、又能保存听力的手术方法。通过实验证实迷路冷冻术可以达到上述目的。经各种动物试验的耳蜗微音电位、组织学检查、变温试验以及行为反应评价低温手术对迷路的影响,表明半规管功能减退出现率与所给的温度和暴露时间有关。在一定的暴露时间,降低冷冻温度可缩短半规管功能消失所需的日数;而温
In patients with Meniere’s disease, some people still have enough hearing, treatment requires the use of both can solve the dizziness, but also save the hearing of the surgical methods. Through experiments confirmed that lost cryogenic surgery can achieve the above objectives. The effects of cryogenic surgery on the labyrinth were assessed by the cochlear microphones potential, histological examination, temperature change test and behavioral response in various animal experiments. The results showed that the incidence of semicircular canal dysfunction was related to the given temperature and exposure time. In a certain exposure time, reduce the freezing temperature can shorten the function of semicircular canal function disappeared days; and warm
