摘要

目的探讨未引出NRT波形的人工耳蜗植入患者的康复效果。方法选取人工耳蜗植入术后患者60例,其中男34例,女26例,年龄2.5～14岁,根据术中能否引出NRT波形分为两组,试验组为术中未引出NRT波形的3例,其余57例术中引出了NRT波形者为对照组,分别测试两组患者开机训练后3个月、6个月的听觉反应阈和语音、声调的识别能力。结果对照组开机后3个月听觉反应阈值、声母识别率、韵母识别率、声调识别率范围分别为35.8±5.5 dB SPL、76.3%±12.8%、81.5%±12.8%、71.4%±15.4%,6个月时分别为34.7±5.5 dBSPL、77.2%±13.9%、82.6%±11.8%、71.4%±15.8%。实验组3个月、6个月的听觉反应阈值和普通话声母、韵母、声调识别率值均在对照组测试结果范围之内。结论术中未引出NRT波形患者的术后康复效果等同于术中可引出NRT波形患者,不宜仅以术中能否引出NRT波形来预测术后康复效果。
