不久以前还认为只有当典型的三联征存在时才能诊断美尼尔氏病,现在情况发生了改变。各种听力测验所积累的大量材料证明,美尼尔氏病的听觉损害有极其特殊之处,据此可在三联征出现前就能较早地确定诊断。作者们认为美尼尔氏病的听功能损害有五个特点:(1)气骨导听阀在所有可听频率范围内均等的升高25～30dB或更多;(2)疾病早期以低频听力损失为主;(3)响度功能紊乱出现很早,不管听敏度损害程度如何,几乎100％存在;(4)言语识别力下降;(5)波动性听力或波动性听力障碍。作者们观察了607例美尼尔氏病患者,发现37％有波动性听力障碍,后者主要包括主观感觉的听敏度波动、纯音听阈测验结
Not long ago, it was thought that Meniere’s disease could only be diagnosed when a typical triad exists, and the situation has now changed. The vast amount of material accumulated in various audiological tests proves that the auditory impairment of Meniere’s disease is extremely peculiar and that the diagnosis can be earlier determined before the triad appears. The authors argue that hearing loss in Meniere’s disease has five characteristics: (1) an equal or greater increase of 25 to 30 dB or more in all audible frequency ranges; and (2) a low frequency Hearing loss; (3) Loudness disorders appear very early, almost 100% regardless of the degree of hearing loss damage; (4) speech recognition decreased; (5) fluctuating or fluctuating hearing disorders. The authors looked at 607 patients with Meniere’s disease and found that 37% had fluctuating hearing impairments, the latter consisting primarily of subjective hearing-related fluctuations,
