We determined the pure-tone hearing thresholds of 25 patients with unilateral active Menière's disease using standard clinical audiometry, high-frequency audiometry (10-18 kHz), and low-frequency audiometry (20-80 Hz). In addition to hearing loss at the conventional frequencies, all of the affected ears showed deterioration of the thresholds at both low- and high-frequency areas as compared with the reference ears. The degree of hearing loss at these frequencies correlated to the degree of the hearing loss at the conventional frequencies, where it was greatest at 0.5-1 kHz. Our findings suggest that in Menière's disease the whole cochlear sensory area is affected, and that the damage caused by Menière's disease advances simultaneously in all parts of the cochlea.
我们使用标准临床听力测定法、高频听力测定法（10 - 18千赫）和低频听力测定法（20 - 80赫兹）测定了25例单侧活动性梅尼埃病患者的纯音听力阈值。除了传统频率的听力损失外，与对照耳相比，所有患耳在低频和高频区域的阈值均显示恶化。这些频率的听力损失程度与传统频率的听力损失程度相关，在0.5 - 1千赫时最为严重。我们的研究结果表明，在梅尼埃病中，整个耳蜗感觉区域均受到影响，并且梅尼埃病所造成的损害在耳蜗的所有部位同时进展。
