// Experimental analysis of cartilage graft positioning in tympanoplasty and its impact on middle ear mechanics
本研究探討軟骨移植物相對於耳骨管位置對鼓膜穿孔後中耳力學的影響｜利用雷射多普勒振動儀與有限元素模型分析，發現移植物置於骨管上或離開骨管對中耳傳導功能無顯著差異｜模型預測臨床效果相似，且將軟骨放置於骨管上可降低併發症風險，且不影響聽力恢復。
// This study investigated how the position of cartilage grafts relative to the bony ear canal affects middle ear mechanics after tympanic membrane perforation. Using laser Doppler vibrometry on human temporal bones and finite element modeling, the researchers found no significant difference in middle ear transfer function between grafts placed on or off the bony canal. The modeling confirmed these results and suggested that in vivo outcomes would be similar, though perforation-related losses are underestimated in open tympanic cavity measurements. Positioning cartilage on the bony canal may reduce complications without harming hearing outcomes.
