This article investigates an effective method with which to reconstruct the tragus and external auditory meatus for microtia reconstruction. The external ear was reconstructed using a delayed postauricular skin flap in patients with congenital microtia. After the first stage of delaying the postauricular skin flap and the second stage of otoplasty with ear framework fabricated from autogenous rib cartilage draping with the delayed skin flap, the third stage involved tragus and external auditory meatus canaloplasty. After designing the remnant auricle flap, the lower part was trimmed and the tragus was reconstructed. The upper part was trimmed into a thin skin flap, which was rotated and used to cover the hollowed wound posterosuperior to the tragus so as to mimic the external auditory meatus. If remnant wounds were present, skin grafting was conducted. In total, 121 patients with congenital microtia were treated from March 2010 to March 2016. The reconstructed tragus and external auditory meatus were well formed, and all wounds healed well. No severe complications such as flap necrosis occurred. Six months postoperatively, the morphology of the reconstructed tragus and external auditory meatus was good. Overall, the patients and their families were satisfied. The use of remnant auricle to reconstruct the tragus and external auditory meatus is an effective auricular reconstruction technique.
本文研究了一种用于先天性小耳畸形重建术中重建耳屏和外耳道的有效方法。对先天性小耳畸形患者采用耳后延迟皮瓣进行外耳重建。在完成耳后皮瓣延迟的第一阶段以及使用自体肋软骨制作耳支架并覆盖延迟皮瓣进行耳成形术的第二阶段后，第三阶段进行耳屏和外耳道成形术。设计残留耳廓皮瓣后，修剪其下部以重建耳屏。上部修剪成薄皮瓣，旋转后用于覆盖耳屏后上方的凹陷创面，以模拟外耳道。若存在残留创面，则进行植皮。2010年3月至2016年3月共治疗121例先天性小耳畸形患者。重建的耳屏和外耳道形态良好，所有创面愈合良好。未发生皮瓣坏死等严重并发症。术后6个月，重建的耳屏和外耳道形态良好。总体而言，患者及其家属满意。利用残留耳廓重建耳屏和外耳道是一种有效的耳廓重建技术。
