Abstract
in English, Chinese

Objective:To explore the development of consonant perception in early implanted pediatric with prelingual bilateral profound sensorineural hearing loss at 1 to 3 years of age. Methods:A retrospective study was conducted to prospectively analyze the pediatric with hearing impaired who had cochlear implantation. According to the age of implantation, all participants were divided into two groups as 1 year old group（1－<2） and 2 years old group（2－<3）. It was compared the consonant perception of Mandarin early speech perception test scores at 1, 2, 3 years after implantation as well as the trends in consonant perception between 1 year old group and normal hearing pediatrics of the same age. Results:①The scores improved notably in two groups with the increase of physiological age（P=0.038, P=0.012）; ②The consonant perception of 1 year old group was significantly better than that of 2 years old group（P<0.05）, however, there are great difference between 1 year old group and normal hearing pediatrics of the same age. Conclusion:With the increase of physiological age, the consonant perception will be improved correspondingly within 3 years of pediatric cochlear implants under the age of 3 however there are differences with normal hearing pediatrics of the same age; the earlier the age of implant, the better the consonant perception is.

目的：初步探讨植入年龄为1~3岁行单侧人工耳蜗植入术（CI）的语前双耳极重度感音神经性听力损失儿童术后3年内声母辨识能力的发育规律。 方法：采用回顾性研究的方法，分析完成CI开机的听力损失儿童声母辨识能力的相关情况。根据植入年龄分为1岁组（1~<2岁）和2岁组（2~<3岁）。采用普通话早期言语感知测试，在开机后1、2、3年时测试CI儿童声母辨识能力，并将1岁组与同龄健听儿童的声母辨识能力的发展趋势进行对比。 结果：①两组CI儿童的声母辨识能力均随着生理年龄的增长而显著提高（P=0.038，P=0.012）；②1岁组的声母辨识能力明显高于2岁组（P<0.05），但与同龄健听儿童相比还存在很大的差异。 结论：术后3年内，植入年龄小于3岁的儿童随着CI佩戴时间的增加其声母辨识能力均有相应提高，但与同龄健听儿童相比还存在着一定的差异；植入年龄越小，声母辨识能力越好。.
