1概念Kamei等(1971)描述了一种以早年出现单侧极重度感音神经性聋,间隔数年后出现眩晕发作为特点的病症。Nadol、Wolfson和Leiberman于1975年也分别描述了类似的病症,1978年Schuknech将这类疾病重新归纳并命名为迟发性膜迷路积水(delayed endolymphatic hydrops,DEH),并将DEH分为3类:同侧型、对侧型及双侧型。
1 Concept Kamei et al. (1971) described a condition characterized by the onset of unilateral maxillary sensorineural hearing loss in the early years and the onset of vertigo after a lapse of years. Similar conditions were also described by Nadol, Wolfson, and Leiberman in 1975. Schuknech reintroduced the disease in 1978 and named it delayed endolymphatic hydrops (DEH) and classified DEH into three categories : Ipsilateral type, contralateral type and bilateral type.
