听障儿童人工耳蜗术后精准调试及效果分析

Precise Mapping and Effect of Cochlear Implant for Hearing-Impaired Children

目的 通过比较人工耳蜗植入儿童调机前后听觉能力、言语清晰度、康复效果等方面的变化,强调术后精准调试的重要性。方法 选取我中心2022年1月~2023年7月就诊的10例人工耳蜗植入儿童,采用听觉能力评估量表(CAP)、言语可懂度分级量表(SIR)比较患儿调机前后的听觉能力和言语可懂度得分,分析调机前后6个电极的电流刺激量情况(22号、20号、15号、10号、5号、1号)。结果 10例儿童都存在电流刺激量设定过高的情况,除5号电极外,其余电极调试前后的C值均有显著差异(P<0.05),6个电极调试前后T值均有显著差异(P<0.05),调试前后CAP和SIR得分均有显著差异(P<0.05)。结论 听障儿童人工耳蜗术后精准调试非常重要,既要注意电流刺激量不足,也要避免刺激量过高。

Objective To compare the changes of hearing ability,speech articulation and rehabilitation effect of children with cochlear implant before and after precise mapping,and to emphasize the importance of precise mapping.Methods Ten cases of children with cochlear implantation treated at our center from January 2022 to July 2023 were analyzed.We used the categories of auditory performance(CAP)and speech intelligibility of rate(SIR)to compare the changes of the children's hearing ability and speech intelligibility before and after the precise mapping.The current stimulation quantity of 6 electrodes(No.22,No.20,No.15,No.10,No.5,No.1)were analyzed before and after mapping.Results All the 10 children had the situation of oversetting of current stimulation.Except for electrode No.5,the C-levels of the other electrodes before and after mapping had significant differences(P<0.05),the T-levels before and after mapping of the 6 electrodes had significant differences(P<0.05),and the CAP and SIR Scores had significant differences(P<0.05).The rehabilitation effect has been significantly improved after mapping.Conclusion The precise mapping after cochlear implantation for hearing-impaired children is very important.we should pay attention to both insufficient current stimulation and excessive stimulation.
