美尼尔氏病有各种外科手术疗法,但皆以破坏迷路功能来达到治疗目的。术中因耳蜗被损,因此术后有听力丧失和伴有面神经麻痹的可能性。此外尚有为减轻内淋巴水肿的内淋巴囊、球囊手术,后者手术操作直接在前庭部位,手术时损伤耳蜗也实为可虑。对此,Arslan氏采取渗透诱导的间接手术方法。术式为经外耳道打开鼓室腔,在蜗窗部放入食盐结晶或中耳腔内注入食盐饱和液,利用渗透压的作用使内耳呈脱水状态以减轻内淋巴水肿及达到治疗美尼尔氏病的目的。根据设想,此手术对听力影响小、操作简便,为了证实是否为优越术式,作者进行了动物实验和临床观察。动物实验:选用鼓膜正常、耳廓反射(Pryer反射)正常、平衡无障碍的300—400克豚鼠,用其右耳作手术实验,左耳为对照。 1.食盐结晶放入蜗窗组:全麻下手术,进入
Meniere’s disease has a variety of surgical therapies, but all have the potential to destroy the lost function. Intraoperative cochlear impaired, so after hearing loss and the possibility of facial paralysis associated with. In addition there are to reduce the lymphatic edema of the lymphatic sac, balloon surgery, the latter directly in the surgical operation of the vestibular site, surgery, cochlear damage is also considered plausible. In this regard, Arslan’s take the indirect method of osmotic induction. Operative method is to open the tympanic cavity through the external auditory canal, salt crystals or the middle ear cavity into the salt solution into the saturated salt solution, the role of osmotic pressure to make the inner ear was dehydrated to reduce endolymphatic edema and achieve the treatment of Meniere’s disease the goal of. According to the hypothesis, this operation has little impact on hearing and is easy to operate. In order to confirm whether it is a superior surgical procedure, the authors conducted animal experiments and clinical observations. Animal experiments: Choose the normal eardrum, auricle reflex (Pryer reflex) normal, balanced barrier 300-400 grams of guinea pigs, with its right ear for surgery, the left ear as a control. 1.
