電極靠近側壁的空間分析及其對ECAP振幅影響：基於OTOPLAN的研究

// Spatial Analysis of Electrode Proximity to Lateral Wall and Its Impact on ECAP Amplitudes: An OTOPLAN-Based Study

本研究探討人工耳蝸電極與側壁距離對電刺激複合神經反應（ECAP）振幅的影響｜44耳高解析度CT與ECAP數據顯示，電極距側壁距離越大，ECAP振幅越高，尤其在耳蝸中段明顯｜結果提示靠近耳蝸中央軸（modiolus）的電極位置，能提升神經反應性，有助優化人工耳蝸程式設定。

// This study examined how the distance between cochlear implant electrodes and the lateral wall affects electrically evoked compound action potential (ECAP) amplitudes. Using high-resolution CT scans and ECAP recordings from 44 ears, the researchers found that larger electrode-to-lateral wall distances correlate with higher ECAP amplitudes, especially in the middle cochlear region. This suggests electrodes positioned further from the lateral wall, closer to the modiolus, may improve neural responsiveness. Electrode-to-lateral wall distance could be a useful metric for optimizing cochlear implant programming.
