Pure-tone audiometry and transiently evoked otoacoustic emission (TEOAE) measurements were made before and after glycerol administration in the ears of sensorineural hearing loss with three different clinical entities, i.e. Meniere's disease, cochlear Meniere's disease and unilateral sensorineural hearing loss of unknown cause without hearing fluctuation (SNHLWF). TEOAE was evoked after glycerol administration in several ears of Meniere's disease and cochlear Meniere's disease, in which it was not evoked before glycerol administration. Especially in patients with cochlear Meniere's disease, TEOAE was altered without an accompanying significant change in mean hearing level. The change in TEOAE after glycerol administration indicates that the active motile property of outer hair cells may be affected by endolymphatic hydrops.
在患有三种不同临床病症的感音神经性听力损失患者耳中，即在梅尼埃病、耳蜗型梅尼埃病和无听力波动的不明原因单侧感音神经性听力损失（SNHLWF）患者中，在甘油给药前后进行了纯音听力测定和瞬态诱发耳声发射（TEOAE）测量。在梅尼埃病和耳蜗型梅尼埃病的几只耳朵中，甘油给药后诱发了TEOAE，而在甘油给药前未诱发。特别是在耳蜗型梅尼埃病患者中，TEOAE发生了改变，而平均听力水平没有伴随显著变化。甘油给药后TEOAE的变化表明，外毛细胞的主动运动特性可能受到内淋巴积水的影响。
