听力波动反映了不同程度的内淋巴积水状态,这种自然听力波动是特发性美尼尔病患者常有的诉说,50%以上可经测听证实。耳聋主要发生于起病后5～10年间,因此,勿论听力损失的类型,均应及早治疗。目前,普遍采用的疗法包括特定饮食、限盐、利尿剂、皮质激素和血管扩张剂等。最近,S chuknecht和Gulya介绍了内淋巴积水症的概念及其分类方法,并将其分为先天性、后天性和特发性。据此,美尼尔病定义为一种特发性症状型内淋巴积水症。波动性聋在内淋巴积水中最常见,瑞典文献报告其发病率为46/100000。【美尼尔病的颞骨特征】断层照相、冷冻显微切片及成形造模方法研究表明,前庭导水管周围气化程度各不相同,可见三种不同的气化类型:1型气房大而多;2型气房小而少或仅有骨髓腔:3型气房缺如。美尼尔病中3型较多而1型少见。前庭导水管周围的气化类型影响着该管管腔的大 Hearing fluctuations reflect different degrees of endolymphatic hydrops, this natural hearing fluctuation is common in patients with idiopathic Meniere’s disease that more than 50% confirmed by audiometry. Deafness occurs mainly in the 5 to 10 years after onset, therefore, regardless of the type of hearing loss should be treated as soon as possible. At present, the commonly used therapies include specific diet, salt restriction, diuretics, corticosteroids and vasodilators. Recently, S chuknecht and Gulya introduced the concept and classification of endolymphatic hydropathy and classified it as congenital, acquired and idiopathic. Accordingly, Meniere’s disease is defined as an idiopathic symptomatic lymphatic hydropathy. Vibrating deafness is most common in endolymphatic hydrops, with a Swedish literature reporting a 46/100000 incidence. [The temporal bone features of Meniere’s disease] tomography, frozen microsection and modeling modeling studies have shown that the gasification around the vestibular aqueduct vary, showing three different types of gasification: 1 type of large air chamber More; type 2 air room small but only or marrow cavity: 3 type of atrial absence. There are 3 types of Meniere’s disease and 1 type is rare. The type of gasification around the vestibular aqueduct affects the lumen of the tube
