Migraine vertigo (MV) and Ménière's disease (MD) share several signs and symptoms such as tinnitus, fullness, photophobia, phonophobia, headache and vertigo spells lasting hours.
The aim of the present study was to prospectively observe patients with MV with a sporadic audiological symptom evaluated with clinical examination, Vestibular Evoked Myogenic Potentials (VEMPs), ECochG and v-HIT.
The finding of VEMP asymmetry, according to our cut-off of 33% of difference between sides, resulted in 20 cases, of which 6 had asymmetry of both c-VEMPs and o-VEMPS, all with development of fluctuating hearing during follow-up. ECochG was positive for endolymphatic hydrops in 12 patients.
The evolution of MV may have a variable course in which some patients may develop symptoms typical of MD. The two diseases may be contextually present at the same time configuring an overlapping syndrome, and asymmetric VEMPs might predict development of fluctuating hearing.
偏头痛性眩晕（MV）和梅尼埃病（MD）有许多共同的体征和症状，如耳鸣、饱满感、畏光、畏声、头痛和持续数小时的眩晕发作。
本研究的目的是前瞻性观察以临床检查、前庭诱发肌源性电位（VEMPs）、ECochG 和 v-HIT 评估的散发性听力症状的 MV 患者。
根据我们 33%的两侧差异的截断值，发现 VEMP 不对称的有 20 例，其中 6 例 c-VEMPs 和 o-VEMPs 均不对称，所有患者在随访期间均出现波动性听力下降。12 例患者的 ECochG 对内淋巴积水呈阳性。
MV 的演变可能具有多变的过程，一些患者可能会出现 MD 的典型症状。这两种疾病可能同时存在，构成重叠综合征，不对称的 VEMP 可能预示着波动性听力下降的发生。
