中文摘要
目的: 探讨根据术前CT扫描在OTOPLAN中按解剖结构估计的电极频率与基于术后锥形束计算机断层扫描(CBCT)的电极频率之间是否存在差异。
研究设计: 单中心回顾性注册研究。
地点: 三级学术医疗中心。
患者: 2004年至2025年间的23名人工耳蜗植入者。
干预: 人工耳蜗植入。
主要结局指标: 比较由术前测量预测的频率图和角度插入深度与由术后DVT影像数据估计的频率图和角度插入深度。此外,频率图应与人工耳蜗拟合软件标准设置提供的频率图进行比较。
结果: 在比较术前CT和术后CBCT时,电极触点1和2没有显著差异。术前估计的频率值比标准设置更接近术后测量值。
结论: 不推荐使用术前扫描来预测基于解剖学拟合的频率图;然而,在谨慎应用时,此类模拟可作为特殊情况下拟合的有用起点。
英文摘要
OBJECTIVES: To investigate whether there is a difference between electrode frequencies estimated in OTOPLAN according to anatomy using a preoperative CT scan and electrode frequencies based on postoperative cone beam computer tomography (CBCT).
STUDY DESIGN: Monocentric retrospective registry study.
SETTING: Tertiary academic medical center.
PATIENTS: Twenty-three CI recipients between 2004 and 2025.
INTERVENTIONS: CI.
MAIN OUTCOME MEASURES: Comparison between frequency maps and angular insertion depth predicted from preoperative measurements and estimated from postoperative DVT imaging data. In addition, the frequency map should be compared with that provided by the standard setting of the CI fitting software.
RESULTS: When comparing preoperative CT and postoperative CBCT, there were no significant differences for electrode contacts 1 and 2. Estimated preoperative frequency values are closer to the postoperative measured values than to the standard settings.
CONCLUSIONS: The use of preoperative scans to predict the frequency map for anatomy-based fitting cannot be recommended; however, when applied with caution, such simulations may serve as a useful starting point for fitting in special cases.
