摘　　要：目的通过对语前聋患儿人工耳蜗植入术后双字词及数字识别能力测试,了解和评估受试儿童在不同年龄段植入人工耳蜗后听觉康复情况。方法选用听力专业测试软件（MAPPID-N）,以双字词和数字听力作为评价指标,对46例人工耳蜗植入年龄在3.3-7.2岁,使用月数为3-24个月的患儿进行听力测试,评估人工耳蜗植入年龄及人工耳蜗使用时间对听觉康复效果的影响。结果人工耳蜗术后,低龄组（≤5岁）与大龄组（〉5岁）双字词及数字听觉能力比较差异具有统计学意义（P〈0.05）,低龄组患者听觉能力较大龄康复快,患者听觉康复能随人工耳蜗使用时间而提高。人工耳蜗植入年龄在4-5岁,听力康复效果最好,此时,使用人工耳蜗7-12个月,双字词听力达到99.75%。数字听力达到99.86%。结论人工耳蜗植入能提高语前聋患者的听觉能力,且植入时间越长,效果越好。患儿接受人工耳蜗最佳的手术年龄宜在5岁以下。对于大龄患儿,进行人工耳蜗植入仍有益于其听觉能力的康复。Objective To evaluate auditory rehabilitation in prelinguistic deafness children with cochlear implantation at different ages by testing their ability to recognize two-word phrases and numbers. Methods Professional hearing test software MAPPID-N was adopted to test the ability to recognize two-word phrases and numbers in 46 prelinguistic deafness children with cochlear implantation. Their ages at implantation ranged from 3. 3 to 7. 2 years old and duration after implantation ranged from 3 to 24 months. The effect of patients ＇ implantation ages and duration after implantation on auditory rehabilitation was statistically analyzed. Results In terms of the two-word phrases and numbers,auditory ability rehabilitation in children with implantation ages younger than 60 months was significantly better than that in those older than or equal to 61 months（ P 0. 05）. Meanwhile,auditory ability could be rehabilitated with increase of duration after implantation. In the children with implantation age of 4 to 5 years old and duration after implantation of 7 to12 months,their abilities for two-word phrases and numbers were 99. 75% and 99. 86% respectively. Conclusions Cochlear implantation can improve auditory ability of prelinguistic deafness children. The younger the cochlea is implanted and the longer the cochlea used,the better auditory ability is. The optimal age for cochlear implantation is younger than 5years old. However,for those who are older than 5,cochlear implantation is still helpful.
