年齡無關的雙側優勢於安靜語音辨識：成人人工耳蝸使用者之匹配縱貫性分析

// Age-Independent Bilateral Advantage in Quiet Speech Recognition: A Matched Longitudinal Analysis of Adult Cochlear Implant Users

本研究比較雙側人工耳蝸（BiCI）與單側（UniCI）在安靜環境下的語音辨識效果｜分析120名成人病患，發現雙側裝置在單音節詞辨識表現顯著優於單側，且此效應不受裝置使用時間影響｜結果支持雙側植入帶來的神經生理優勢，有助推動成人雙側植入政策，但仍需更大規模研究確認並探討其神經機制。

// This study examined whether bilateral cochlear implants (BiCI) provide better speech perception in quiet than unilateral implants (UniCI) by analyzing 120 well-matched adult patients over 12 months. Using longitudinal models, BiCI showed a significant advantage for monosyllabic word recognition that was not due to greater device use and was consistent across age groups. The findings suggest that BiCI benefits arise from neurophysiological mechanisms rather than motivational factors and support expanding adult bilateral implantation coverage. Further large studies are needed to confirm these results and explore underlying neural processes.
