電動與手動耳蝸植入術後阻抗的時間演變

// Temporal evolution of impedance after motorized versus manual cochlear implantation

本研究比較電動插入工具（MITs）與手動方式在殘餘聽力患者人工耳蝸電極植入的效果｜術後6個月測量基底耳蝸阻抗值，發現MIT輔助插入能降低阻抗，顯示減少耳蝸內組織損傷｜雖然聽力保存率相似，但MIT有助於降低機械應力，阻抗數據成為評估組織反應的重要指標。

// This study compared motorized insertion tools (MITs) with manual insertion for cochlear implant electrode placement in patients with residual hearing. Using matched cohorts, impedance values were measured over six months postoperatively to assess tissue response and hearing outcomes. MIT-assisted insertion resulted in consistently lower impedance in the basal cochlea, indicating reduced intracochlear trauma, though overall hearing preservation was similar between methods. These results suggest MITs may minimize mechanical stress during insertion, with impedance metrics serving as useful biomarkers.
