摘要
研究目的本研究旨在评估人工耳蜗植入术后不同电极类型的电诱发复合动作电位(ECAP)阈值和术后映射电流(T)水平的差异、ECAP阈值和T水平之间的相关性,以及机器学习技术在预测术后T水平方面的性能:背景:三级医院地点:三级医院:干预措施:比较 ECAP 阈值和 T 水平:我们比较了来自不同电极的ECAP阈值和T水平,计算了ECAP阈值和T水平之间的相关性,并创建了5个T水平预测模型,用于预测开机时和术后6个月的T水平:主要结果指标:术后映射电流(T)水平预测的准确性:结果:细长的小叶电极的ECAP阈值明显低于心尖侧的直电极。然而,基底侧两个电极的神经反应遥测阈值没有明显差异。在该数据集中,Lasso 回归对开关机时的 T 水平预测最为准确,随机森林算法对术后 6 个月的 T 水平预测最为准确:机器学习技术有助于准确预测儿童人工耳蜗植入术后的 T 值。
Prediction of Cochlear Implant Fitting by Machine Learning Techniques.
Objective: This study aimed to evaluate the differences in electrically evoked compound action potential (ECAP) thresholds and postoperative mapping current (T) levels between electrode types after cochlear implantation, the correlation between ECAP thresholds and T levels, and the performance of machine learning techniques in predicting postoperative T levels.
Study design: Retrospective case review.
Setting: Tertiary hospital.
Patients: We reviewed the charts of 124 ears of children with severe-to-profound hearing loss who had undergone cochlear implantation.
Interventions: We compared ECAP thresholds and T levels from different electrodes, calculated correlations between ECAP thresholds and T levels, and created five prediction models of T levels at switch-on and 6 months after surgery.
Main outcome measures: The accuracy of prediction in postoperative mapping current (T) levels.
Results: The ECAP thresholds of the slim modiolar electrodes were significantly lower than those of the straight electrodes on the apical side. However, there was no significant difference in the neural response telemetry thresholds between the two electrodes on the basal side. Lasso regression achieved the most accurate prediction of T levels at switch-on, and the random forest algorithm achieved the most accurate prediction of T levels 6 months after surgery in this dataset.
Conclusion: Machine learning techniques could be useful for accurately predicting postoperative T levels after cochlear implantation in children.
