基於術前電腦斷層（CT）影像之電極位置估計用於人工耳蝸受者解剖學基礎配適之可行性

// Feasibility of Electrode-Location Estimates Based on Preoperative CT-Imaging for Anatomy-Based Fitting in Cochlear Implant Recipients

回顧性單中心23例研究，OTOPLAN以術前CT預測電極頻率圖與插入角度｜術前估算與術後CBCT在第1、2接點無顯著差異，且術前結果較接近術後實測而非裝置預設頻率｜結論：不建議作為常規解剖式調配，但可於特殊個案謹慎作為起點

// This retrospective single-center study of 23 cochlear implant recipients compared electrode frequency maps and angular insertion depth predicted by OTOPLAN from preoperative CT with measurements from postoperative CBCT and with standard CI fitting. There were no significant differences for electrode contacts 1 and 2 between pre- and postoperative imaging, and preoperative estimates aligned more closely with postoperative measurements than with the implant's standard frequency settings. Despite this, CT-based preoperative predictions are not recommended for routine anatomy-based fitting but may be used cautiously as a starting point in special cases.
