目的：评估耳蜗植入后儿童发育（CDACI）多中心研究中纳入的耳蜗植入儿童的映射特征。研究设计：前瞻性纳入研究的耳蜗植入儿童在24个月期间的语音处理器映射的纵向评估。设置：6个三级转诊中心。受试者：188名儿童入组CDACI研究，入组时年龄为5岁或以下。在这些儿童中，184人接受了单侧种植体，4人同时接受了双侧implants.Intervention：作为研究方案的一部分，儿童在他们的种植诊所参加了定期的映射会议。在4个不同的时间间隔检查每个受试者的标测图：在装置激活时和激活后6、12和24个月。比较了4个不同时间间隔、3种不同器械、6个不同植入中心以及正常和异常耳蜗儿童的耳蜗植入率（每个阶段的负责人）。所有3种类型的植入器械均显示出器械激活与24个月预约之间的C/M水平显著增加。观察到器械之间的平均C/M水平存在显著差异。耳蜗异常的儿童表现出显着更大的C/M水平比儿童正常cochleae.Conclusion：CDACI研究使我们能够评估使用3种不同的设备，并在各种植入中心植入的儿科患者的映射特性。对这些数据的分析使我们能够更好地了解人工耳蜗植入儿童的映射特征。
Objective: To evaluate mapping characteristics of children with cochlear implants who are enrolled in the Childhood Development After Cochlear Implantation (CDACI) multicenter study.Study Design: Longitudinal evaluation during 24 months of speech processor maps of children with cochlear implants prospectively enrolled in the study.Setting: Six tertiary referral centers.Subjects: One hundred eighty-eight children enrolled in the CDACI study who were 5 years old or younger at the time of enrollment. Of these children, 184 received unilateral implants, and 4 received simultaneous bilateral implants.Intervention: Children attended regular mapping sessions at their implant clinic as part of the study protocol. Maps were examined for each subject at 4 different time intervals: at device activation and 6, 12, and 24 months postactivation.Main Outcome Measures: Mean C/M levels (in charge per phase) were compared for 4 different time intervals, for 3 different devices, for 6 different implant centers, and for children with normal and abnormal cochleae.Results: All 3 types of implant devices demonstrate significant increases in C/M levels between device activation and the 24-month appointment. Significant differences in mean C/M levels were noted between devices. Children with cochlear anomalies demonstrate significantly greater C/M levels than children With normal cochleae.Conclusion: The CDACI study has enabled us to evaluate the mapping characteristics of pediatric patients who use 3 different devices and were implanted at a variety of implant centers. Analysis of such data enables us to better understand the mapping characteristics of children with cochlear implants.
