【摘要】 目的对语后聋成年人工耳蜗植入者的言语识别能力和术后生活质量进行评估,并探讨二者之间的相关性。方法 12例植入手术半年以上的语后聋人工耳蜗植入者,男性5例,女性7例。应用噪声下普通话言语测试系统(Mandarin Hearing in Noise Test,MHINT)评估植入者在安静条件下和噪声条件下的言语识识别能力,其噪声条件下测试以每一个体在安静条件下所得言语识别率的50%为标准,获得该标准下的信噪比;应用Nijmegen人工耳蜗植入量表(Nijmegen Cochlear Implantation Questionnaire,NCIQ)评价植入者的术后生活质量。结果所有植入者术后言语识别率和生活质量均有明显改善。①安静条件下平均言语识别率为63.5±26.6%;②噪声条件下的平均信噪比为10.3±3.7dB;③NCIQ总分及基本声音感知、高级声音感知、言语功能、自信心、活动能力和交流能力等六个子维度得分均有改善(P<0.05);④NCIQ总分及各子维度得分与言语测试结果间均无显著相关(P>0.05)。结论语后聋成年人工耳蜗植入者术后生活质量获得显著改善,其自我主观评价明显优于言语识别能力评价。更多还原

【Abstract】 Objective To evaluate impacts of cochlear implantation on speech perception and quality of life in postlingual deaf adults. Method Twelve adult cochlear implant users (7 females and 5 males) participated in this study. Mandarin Hearing in Noise Test (MHINT) was used to assess speech perception. Test score in noise was defined as the signal-to-noise ratio (SNR) at which speech perception in noise was approximately 50% of the score in quiet. The Nijmegen Cochlear Implantation Questionnaire (NICQ) was administered to quantify quality of life. Result Cochlear implants demonstrated a large and significant positive impact on quality of life and auditory perception. 1) The average speech perception scores in quiet was 63.5% (SD=26.6). 2) The average score in noise was 10.3 dB (SD=3.7). 3) Differences between pre- and post-implant total and all sub-domain NCIQ scores were statistically significant (P < 0.05). 4) No obvious correlations were found between NCIQ outcomes and auditory perception (P >0.05). Conclusion Cochlear implants have a large and significant positive impact on quality of life. Improvement in quality of life is greater than that in auditory perception.更多还原
