175例语前聋患儿人工耳蜗植入术后听觉言语康复效果的评估

The evaluation of auditory and speech abilities of 175 prelingually deaf children after cochlear implantation

目的评估语前聋患儿人工耳蜗植入术后的听觉言语康复效果。方法收集2009-2013年于郑州市康园听力言语康复中心康复的175例语前聋患儿的详细资料,根据人工耳蜗植入时的年龄将研究对象分为两组(3岁及以下组和3岁以上组),应用婴幼儿听觉整合量表(IT-MAIS/MAIS)、听觉行为分级(CAP)及言语可懂度分级(SIR)对两组患儿听觉言语能力进行评估,评估分别在人工耳蜗植入术后的1、3、6、12个月进行。结果在人工耳蜗植入术后1、3、6、12个月,两组总体康复效果均逐步提高(P均<0.01);3岁及以下组提高较3岁以上组快。IT-MAIS/MAIS与CAP分级之间存在显著正相关性。结论随着康复时间的延长,语前聋患儿听觉言语康复效果呈逐步上升趋势。康复时间和植入时年龄是影响语前聋患儿人工耳蜗植入术后听觉言语康复效果的重要因素。

Objective To evaluate the auditory and speech abilities of prelingually deaf children after cochlear implantation.Methods 175 prelingually deaf children treated in Kangyuan Auditory and Speech Rehabilitation Center of Zhengzhou from 2009to 2013 were included in this study. According to the age at implantation,the children were divided into 2 groups based on if their ages were older than 3 years or not. The questionnaires of IT-MAIS / MAIS,CAP and SIR were used to evaluate the auditory and speech abilities. The evaluation was presented 1,3,6 and 12 months after cochlear implantation. Results The rehabilitation effects of two groups were gradually improved after cochlear implantation( P < 0. 01). The performance of auditory and speech rehabilitation in implantees who were younger than 3 years old elevated more promptly than the other group. There was a remarkable positive correlation between IT-MAIS / MAIS and CAP. Conclusion The auditory and speech abilities of prelingually deaf children have a gradually rising trend with the extension of rehabilitation time. Duration of rehabilitation and age at implantation are the two important factors affecting postoperational rehabilitation effects.
