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. 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. ①The scores improved notably in two groups with the increase of physiological age（=0.038, =0.012）; ②The consonant perception of 1 year old group was significantly better than that of 2 years old group（<0.05）, however, there are great difference between 1 year old group and normal hearing pediatrics of the same age. 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.
探讨1至3岁早期植入人工耳蜗的语前双侧重度感音神经性听力损失儿童的辅音感知发展情况。进行一项回顾性研究，对接受人工耳蜗植入的听力受损儿童进行前瞻性分析。根据植入年龄，将所有参与者分为两组，即1岁组（1－<2岁）和2岁组（2－<3岁）。比较植入后1年、2年、3年时普通话早期言语感知测试分数的辅音感知情况，以及1岁组与同龄正常听力儿童之间辅音感知的变化趋势。①两组的分数均随着生理年龄的增长而显著提高（=0.038，=0.012）；②1岁组的辅音感知明显优于2岁组（<0.05），然而，1岁组与同龄正常听力儿童之间存在很大差异。在3岁以下儿童人工耳蜗植入后的3年内，随着生理年龄的增长，辅音感知会相应提高，但与同龄正常听力儿童存在差异；植入年龄越早，辅音感知越好。
