摘　　要：目的：探讨低年龄段经人工耳蜗植入的语前聋儿童经过开机一段时间后声调识别的变化特点。方法：选择29例已经接受人工耳蜗植入的低年龄语前聋儿童，按植入时年龄分为2组，即A组：3．0～4．5岁，B组：5．O～6．5岁，植入后平均开机时间为1．5～2．0年。采用聋康系统的《聋儿听觉言语康复评估词表》中主要反映声调识别的相应评估内容进行封闭项测试。结果：A组：同音单音节声调识别率为（63．00±16．75）％，双音节声调识别率为（75．60±11．18）％，单音节词识别率为（72．38±11．39）％。B组：同音单音节声调识别率为（49．46±13．91）％，双音节声调识别为（64．71±9．64）％，单音节词识别率为（55．71±8．59）％。所有正确识别率结果均大于机会水平。人工耳蜗植入后不同年龄组患儿有关声调识别的三项测试内容，低年龄组患儿均好于高年龄组，结果均差异有统计学意义。结论：对于语前聋行人工耳蜗植入的低年龄儿童，植入时年龄仍是影响植入后声调识别的重要因素之一，而在更能反映汉语声、韵、调特点的单音节词中差异更为明显，因此植入年龄是术后汉语学习的重要影响因素之一。Objective：To analyze the changing features of mandarin-tone recognition in lower prelingual children with cochlear implant after mapping. Method：Twenty-nine children with CI were registered in this test, who were divided into two groups according to the age received the operation. They were group A whose ages were 3 to 4.5 years old, and group B whose ages were 5.0 to 6.5 years old. The time after first mapping was between 1.5 and -2.0 years. The test only included close-set phonetic recognition which was mainly used to evaluate Mandarin-tone recognition. The Phonetic Recognition List was used as the test material. Result： The results showed that the percentages of correct recognition were same-single-syllable tones average （63.00±16.75）%; bi-syllable tones average （75.60±11.18）%;single-character words average （72.38±11.39）% in A group children and respectively, （49.46±13.91）%; （64.71±9.64 ）%;（55.71 ±8.59）% in B group children. The recognition scores exceeded chance level in all results and they were better in A group. Statistical analysis（t test） showed significant difference between two groups. Conclusion：The age is one of the most influence factors about Mandarin-tone recognition after implanting in pre-lingual children with CI. It is another important factor to influence studying Chinese after operation in the children.
