摘　　要：目的　通过对植入人工耳蜗的语前聋儿童和青少年的听力和语言能力的评估 ,探讨我国儿童在使用人工耳蜗后的听力和言语能力发展规律及影响因素。方法　 2 5例行人工耳蜗植入的语前聋儿童及青少年患者参与本组测试。选用《聋儿听觉言语康复评估方法》作为测试材料 ,分别进行声音、言语声和环境声的辨别 ,数词、单字词、双字词、3字词、韵母、声母、声调、封闭项列短句的识别 ,开放项列字词和开放项列短句识别 ,语言清晰度 ,模仿句长 ,听话识图和看图说话等方面测试。结果　受试者术后均能感知到声音 ,辨别不同类别的声音。封闭项列测试结果全部大于机会水平 ,正确识别率随人工耳蜗使用时间而不断增加 ,随植入时年龄的增长而呈下降趋势。术后约半年显现开放项列识别能力 ,使用人工耳蜗后对患儿的言语发育具有较大帮助。结论　尽早对语前聋患儿植入人工耳蜗及进行术后康复 ,以达改善听力 ,提高语言能力 ,促进身心全面发展的目的。Objective To assess the development of hearing and language in prelingually deafened children with implanted multichannel cochlear prosthesis from the mandarin speaking area, and to explore the basic pattern of speech recognition and language development as well as influencing factors Methods Twenty five prelingually deafened children and youths with cochlear implant participated in this study Using “Evaluating method on hearing and speech rehabilitation in deafened children” as a test material These materials consist of speech and environment sound discrimination, closed set and open set speech recognition and language development tests Results All patients had the ability to hear sound and could discriminate different categorical sounds Results indicated that the score of closed set test exceeded the chance level The correct recognition rate was escalating with prolonging the implanted time Contrarily, the correct recognition rate was de escalating as implanted age increased Subjects having significant open set speech recognition half year after the operation, indicated that the cochlear implant can promote prelingually deafened children to develop their speech level Conclusion Once the diagnosis of profoundly sensorineural hearing loss is made, the optimal treatment of choices is cochlear implant and speech rehabilitation
