儿童及青少年人工耳蜗植入术后疗效影响因素分析

Evaluation of the Curative Effect after Cochlear Implantation in Children and Adolescents

目的评估儿童和青少年人工耳蜗植入术后听觉和言语感知发展,探讨哪些因素与预测术后效果有关。方法选取128名儿童和青少年,均为语前双侧重度感音神经性听力损失。收集所有受试者术后听觉言语情况,以及植入年龄、人工耳蜗使用时间、受试者接受的教育系统及家长文化水平。以听觉感知类别(CAP)和语言清晰度(SIR)结果测量康复效果。结果①植入年龄越小,预后越好;②听觉表现和语言清晰度在术后2年趋于平稳;③在主流学校就读的学生较聋哑学校学生预后更好。结论语前聋儿童及青少年人工耳蜗植入年龄、使用人工耳蜗的时间、接受的教育系统是评估言语预后结果的相关因素。

Objective To evaluate the development of auditory and speech perception in children and adolescents after cochlear implantation and to determine which factors are associated with predicting postoperative outcome.Method 128 children and adolescents participated in this study.All subjects had prelingual bilateral severe sensorineural hearing loss.Postoperative auditory and speech performance was collected for all subjects,as well as age at implantation,duration of cochlear implant use,educational system received by the subject,and primary parent's literacy level.The categorical auditory performance(CAP)and speech intelligibility rating(SIR)were used as outcome measures.Results The younger the implantation age was,the better the prognosis;Auditory performance and speech articulation tended to be stable two years after surgery;Patients who attended mainstream schools had a better prognosis than those who attended deaf schools.Conclusion The age of cochlear implantation in children and adolescents with prelingual deafness,the duration of cochlear implant use and the educational system the patient receives are all relevant factors in assessing the prognostic outcome of speech.
