Improvement of hearing after excision of an acoustic neuroma has been observed infrequently. We present a case of dramatic recovery of hearing in a patient with a 1-cm acoustic neuroma whose pure-tone thresholds and speech discrimination had profoundly deteriorated while she awaited surgical therapy. Postoperatively, her hearing in the affected ear is equal to that in her other ear, and her speech discrimination exceeds that of her best preoperative audiogram. Issues related to hearing preservation and improvement after acoustic tumor surgery are discussed.
听神经瘤切除术后听力改善的情况鲜有报道。我们报告一例患有1厘米听神经瘤的患者听力显著恢复的病例，该患者在等待手术治疗期间纯音听力阈值和言语识别能力严重恶化。术后，她患侧耳朵的听力与另一侧耳朵相当，且言语识别能力超过术前最佳听力图的水平。本文讨论了听神经瘤手术后听力保留和改善相关的问题。
