听力损害是多发性硬化症(multiple sclerosisMS)的一个少见的始发的或突出的症状。本文报告9例。临床症状男1例,女8例,年龄21～53岁,7例单侧听力丧失,2例为双侧。1例有对侧耳聋发作,最近一次发作前2年听力有恢复。4例听力丧失是MS的首发症状,发生于起病后1年内2例,余3例分别为2、4及11年。伴有耳鸣和/或眩晕5例,躯干或步态共济失调6例,眼震5例,肢体共济失调5例,痉挛性轻偏瘫或轻截瘫3例,眼肌轻瘫3例,同侧面部麻木或无力2例,舌无力或麻木2例,面偏侧痉挛2例。8例病程有加重和缓解过程。随访1～12年,改善者5例,稳定3例,进行性恶化1例。听功能检查 7例测定了气、骨导纯音阈,2例仅检查了气导阈,所有病人均未发现气、骨导距离增大。9例中7例发现异常(任何频率的听力损害>
Hearing impairment is a rare, prevalent or prominent symptom of multiple sclerosis MS. This article reports 9 cases. Clinical symptoms 1 males and 8 females, aged 21 to 53 years, 7 cases of unilateral hearing loss, 2 cases were bilateral.
