文献信息

中文摘要

目的： 本研究探讨了使用自动ART（AutoART）方法获得的电诱发复合动作电位（eCAP）阈值与儿童人工耳蜗（CI）使用者的行为阈值水平（THR）、最大舒适水平（MCL）和电极阻抗值之间的关系。还检查了不同电极区域之间的差异以及电极类型、植入物型号、植入耳侧和性别的影响。
方法： 纳入30名年龄7-18岁、使用MED-EL植入物且所有电极均具有可靠eCAP反应的儿童CI使用者。使用MAESTRO 11.0的AutoART方法自动获得eCAP阈值。行为THR和MCL值通过标准编程程序确定，阻抗值通过遥测记录。
结果： eCAP阈值、THR和MCL值从顶端电极到基底电极显著增加。eCAP阈值在所有区域均与行为THR和MCL呈正相关。回归分析表明，eCAP阈值是THR尤其是MCL的最强预测因子，而阻抗没有显著贡献。最强的相关性观察于顶端区域。
结论： 基于AutoART的eCAP测量提供了一种可靠的客观指标，支持儿童CI使用者的行为编程。

英文摘要

PURPOSE: This study investigated the relationship between electrically evoked compound action potential (eCAP) thresholds obtained using the Automatic ART (AutoART) method and behavioral threshold level (THR), maximum comfort level (MCL), and electrode impedance values in pediatric cochlear implant (CI) users. Differences across electrode regions and the effects of electrode type, implant model, implant ear side, and gender were also examined.
METHODS: Thirty pediatric CI users aged 7-18 years with MED-EL implants and reliable eCAP responses from all electrodes were included. eCAP thresholds were obtained automatically using the AutoART method with MAESTRO 11.0. Behavioral THR and MCL values were determined using standard programming procedures, and impedance values were recorded via telemetry.
RESULTS: eCAP thresholds, THR, and MCL values increased significantly from apical to basal electrodes. eCAP thresholds were positively correlated with behavioral THR and MCL across all regions. Regression analyses indicated that eCAP thresholds were the strongest predictors of both THR and especially MCL, while impedance did not significantly contribute. The strongest correlations were observed in the apical region.
CONCLUSION: AutoART-based eCAP measurements provide a reliable objective indicator supporting behavioral programming in pediatric CI users.
