有关美尼尔氏病的纯音测听曲线图形,早期文献已有详细描述。Enander & Stable(1967)分析334例,以平坦型曲线最常见,占60%;其次为上升型与下降型,分别占17%与12%;少数呈凹槽型,占7%;另有4%听力损失严重,曲线断缺而不能分型。上升型听力损失最少,平均为44dB;不能分型的最重,为91dB。听力与病程的关系,不到6个月者听力损失较少,但在一年之内即明显下降,平均达50dB,此后即使病程久长而听力恶化则较轻微。波动性听力为本病的特点,彼等发现52%病员重复测定时出现波动听力,以上升型曲线的听力波动最多,凹槽型次之。病
Pure sound audiometry curves on Meniere’s disease have been described in detail in earlier literature. Ender & Stable (1967) analyzed 334 cases, with flat curves the most common, accounting for 60%; followed by ascending and descending, accounting for 17% and 12% respectively; a few were concave, accounting for 7%; and another 4 % Severe hearing loss, broken curve but can not type. Rising hearing loss at least, with an average of 44dB; can not type the heaviest, 91dB. Hearing and duration of the relationship between less hearing loss less than 6 months, but within a year that dropped significantly, an average of 50dB, since then, even if the longer duration of hearing loss is less serious. Vibratory hearing is characteristic of this disease, and they found that fluctuating hearing was present in 52% of the patients with repeated measures, with the largest increase in hearing fluctuation and the second in recess. disease
