// Cochlear size variation in a large-scale international multicentre cohort
本研究透過文獻資料與OTOPLAN®軟體分析，評估耳蝸基底迴直徑（A值）與寬度（B值）的變異｜共蒐集5,206筆文獻A值及5,580筆臨床測量，平均A值約9.07毫米，顯示耳蝸尺寸範圍較先前報告更廣｜結果發現全球耳蝸尺寸及形狀差異顯著，約69%耳蝸基底迴呈橢圓形，揭示耳蝸解剖多樣性超乎以往認知。
// This study reviews cochlear size variation by analyzing the basal turn diameter (A-value) and width (B-value) using literature data and measurements from the OTOPLAN® software across international centers. A scoping review gathered 5,206 literature A-values and 5,580 clinical OTOPLAN® measurements, showing a mean A-value around 9.07 mm with a wider anatomical range than previously reported. The study finds significant variation in cochlear size and shape globally, with about 69% of cochleae having an elliptical basal turn shape. These findings highlight greater anatomical diversity in cochlear dimensions across populations than earlier studies indicated.
