诺尔康人工耳蜗植人者的声调识别与生活质量评价

目的：评估诺尔康人工耳蜗植入者对普通话的声调识别能力和术后生活质量。方法：49例植入诺尔康人工耳蜗1年的受试者，使用课题组前期编制的声调识别测试软件，评估植入者的声调识别能力；使用Ni-jmegen人工耳蜗植入量表（NCIQ），评估植人者术后生活质量。结果：①安静条件下声调识别率平均为67．26％，全部高于机会水平；②噪声条件下声调识别率平均为51．92％，除2例植入者的声调识别率低于机会水平外，其余均高于机会水平；③声调识别混淆矩阵结果显示，三声为较容易辨别的声调；④术后NCIQ总分及基本声音感知、高级声音感知、言语能力、自信心、活动能力和交流能力均获得改善，分别为55．4、72．4、54．0、63．4、50．7、47．3和44．7分。结论：诺尔康人工耳蜗植入者术后具有声调识别能力并可获得生活质量的改善。

Lexical tone perception and quality of life in Nurotron cochlear implant users

Objective：To investigate the lexical tone perception and quality of life of Nurotron cochlear implant users. Method： Forty-nine adult cochlear implant users participated in this study. Mandarin tone identification test developed by Beijing Institute of Otolaryngology was used to evaluate the tone perception. Nijmegen cochlear im-plantation questionnaire（NCIQ） was administered to quantify the quality of life. Result： ①The average scores of tone perception in quiet was 67.26%. The tone perception rates under quiet condition for all cochlear implant re-cipients were higher than the opportunity level. ②The average scores of tone perception under noisy condition was 51.92%. Except for two recipients, the tone perception rates under noise condition for the rest recipients werebetter than chance. ③The confusion patterns of tone recognition showed that Tone 3 was the easiest tone to per-ceive. ④The postimplant scores for the total , basic sound perception , advanced sound perception, speech pro- duction, self-esteem, activity and social interactions of NCIQ were 55.4,72.4,54.0,63.4,50.7,47.3 and 44.7, respectively. Conclusion：The Nurotron cochlear implant users had the ability for lexical tone perception and had an improvement in quality of life after cochlear implantation.
