3D列印中耳義肢長度變化對聽小骨鏈活動度之影響

// Effect of length variations in 3D-printed middle-ear prostheses on ossicular chain mobility

本研究測試不同長度的客製化3D列印聽小骨義肢對人類顳骨中耳振動的影響｜製作三種長度（原長＋0%、＋10%、＋20%）義肢並測量聲音誘發振動，發現長度變化對中耳運動頻率依賴性影響顯著，但整體無統計顯著差異｜結果顯示義肢設計需在手術中精確調整尺寸，以兼顧張力與穩定性，提升患者個別治療效果。

// This study tested how changing the length of a custom 3D-printed ossicular prosthesis affects middle-ear movement in human temporal bones. Researchers printed three prostheses of varying lengths (+0%, +10%, +20%) and measured sound-induced vibrations. They found that length changes influenced middle-ear mobility depending on frequency but did not produce statistically significant differences overall. The results suggest that patient-specific prosthesis design should incorporate careful intraoperative sizing to balance tension and stability.
