迟发性内淋巴水肿(delayed eadolymphatichydrops DEH)作为陈旧性重度内耳性聋的迟发性合并症而发病,产生膜迷路渐进性复发性内淋巴水肿。结果表现为类似美尼尔氏病的前庭症状。1976年确立了本病概念并命名。并分为同侧型(ipsilateral DEH)和对侧型(contralateralDEH)两型,还有人报告有双侧型(bilateraltypeDEH),但临床极少见。1.DEH 诊断标准在同侧型 DEH 为:①单耳重度感音性聋或全聋(初期);②出现美尼尔氏病样前庭症状(后期);③眩晕发作时不伴听力改变;④无中枢症状。对侧型 DEH 为:①单耳重度感音性聋或全聋(初期);②健耳出现新的内耳性聋(后期);③健耳听力改变;④有时出现美尼尔氏病样前庭症状
Delayed endolymphatic hydrops DEH develops as a late comorbidity of old, severe inner ear deafness and produces progressive labyrinthine membrane lymphatic edema. The results showed a similar Meniere’s disease vestibular symptoms. 1976 established the concept of the disease and named. And divided into ipsilateral (ipsilateral DEH) and contralateral (contralateral DEH) two types, there were reports of bilateral type (bilateraltypeDEH), but the clinical rare. 1. DEH diagnostic criteria in the ipsilateral type of DEH is: ① severe sensory hearing loss or deafness of the whole ear (initial); ② appearance of Meniere’s disease-like vestibular (late); ③ vertigo episodes without hearing changes; ④ no central symptoms. Contralateral DEH: ① severe hearing loss of a single ear or deafness (initial); ② auricular new onset of hearing loss (late); ③ hearing loss hearing; ④ sometimes appear Meniere’s disease-like vestibule symptom
