The progression of hearing loss and the factors influencing it are not well understood in patients with acoustic neuroma (AN). We investigated the relationships between the progression of hearing loss and the clinical findings in 42 patients with unilateral AN whose hearing could be examined for a period of 6 months or more. There was a tendency for hearing to deteriorate progressively in the patients with retrocochlear hearing loss, or with a small tumor. Based on these results, we conclude that an operation for hearing preservation should be performed as early as possible in these patients.
在听神经瘤（AN）患者中，听力损失的进展情况及其影响因素尚未得到充分了解。我们调查了42例单侧听神经瘤患者听力损失进展与临床发现之间的关系，这些患者的听力可进行6个月或更长时间的检查。蜗后性听力损失患者或肿瘤较小的患者存在听力逐渐恶化的趋势。基于这些结果，我们得出结论，对于这些患者应尽早进行听力保留手术。
