耳蝸植入術中非侵入性間接耳蝸內壓監測

// Noninvasive indirect intracochlear pressure monitoring during cochlear implantation

本研究開發非侵入式方法，利用置入耳道的探測麥克風監測人工耳蝸植入手術中的耳蝸內壓力變化｜透過反向中耳傳遞函數估算顳骨標本與患者手術期間的壓力，並發現圓窗開啟及電極插入時聲壓明顯升高，與直接測量數據吻合，驗證此方式可靠｜此技術有助即時監控聲壓暴露，提升手術中聽力保護效果，具臨床應用潛力。

// This study explores a noninvasive method to monitor intracochlear pressure during cochlear implantation using a probe microphone in the ear canal. By applying a reverse middle-ear transfer function, the authors estimate intracochlear pressure changes during surgery in both temporal bones and patients. They observed high acoustic pressure events, particularly during round window opening and electrode insertion, matching direct measurements, validating the approach. The findings suggest this technique can enable real-time monitoring of acoustic exposure to improve hearing preservation during surgery.
