To introduce our 2-stage reconstruction of microtia method, which results in a natural-looking contour of the reconstructed ears, one of the most demanding challenges in facial plastic surgery.
In the first stage, the 3-dimensional cartilage framework is fabricated. The skin flap and retroauricular fascial flap are elevated in the mastoid area. Then the framework is wrapped by the fascial flap from behind and covered by the skin flap from front. In the second stage the crus, the tragus, and the conchal cavity are reconstructed. So almost all of the fine structures of ear are reconstructed.
Sixty-eight patients ranging in age from 5 to 17 years had their ears reconstructed using our 2-stage method from January 1, 2006, to December 31, 2008. Forty-eight patients were boys, and 20 were girls. Unilateral microtia was present in 66 patients and bilateral microtia was present in 2 patients. The reconstructed ears had a 3-dimensional configuration, and the cranioauricular angle of the reconstructed ears was similar to that of the contralateral ear.
Two-stage ear reconstruction is a simple and promising method for microtia. Furthermore, the complications are rare.
介绍我们的两期小耳畸形重建方法，该方法能使重建耳呈现自然的轮廓，这是面部整形手术中最具挑战性的难题之一。
第一期，制作三维软骨支架。在乳突区掀起皮瓣和耳后筋膜瓣。然后将支架从后方用筋膜瓣包裹，从前方用皮瓣覆盖。第二期，重建耳上脚、耳屏和耳甲腔。这样几乎重建了耳朵的所有精细结构。
2006年1月1日至2008年12月31日，68例年龄在5至17岁的患者采用我们的两期方法进行了耳重建。其中48例为男性，20例为女性。66例为单侧小耳畸形，2例为双侧小耳畸形。重建耳具有三维形态，重建耳的颅耳角与对侧耳相似。
两期耳重建是一种治疗小耳畸形的简单且有前景的方法。此外，并发症罕见。
