“双瓣”技术在耳廓再造中的应用

Implication of technique of "two-flap" in ear reconstruction

目的:探讨"双瓣"技术在耳廓再造中的应用。方法:第1期手术行皮肤定量扩张器埋置,注水治疗完毕后维持扩张1个月。第2期设计扩张的耳前皮瓣和未扩张的筋膜瓣,应用"双瓣"技术进行耳廓再造术。于2004-01-2008-12共应用扩张的耳前皮瓣和未扩张的耳后筋膜瓣的"双瓣"技术实施耳廓再造1427只。结果:扩张的耳前皮瓣能够清晰显现再造耳廓表面细微结构;未扩张的耳后筋膜瓣形成良好的颅耳沟,再造耳廓立体感强。结论:"双瓣"技术操作简单、并发症较少,再造耳廓不仅形态逼真而且具有立体结构。

Objective：To explore the technique of ＂two-flap＂ in ear reconstruction. Method：Quantitative tissue expansions were used in the mastoid area in the first stage. After the final injection, there was 1 month of sustaining time. Expanded skin flap and unexpanded fascia flap were designed in the second stage, so the ＂two-flap＂ technique was used in the ear reconstruction. From January 2004 to December 2008, 1 427 patients of mierotia were treated using ＂two-flap＂ technque. Result：The expanded skin flap could show the fine structures of the reconstructed ears. The reconstructed ears had vivid cranioauricular angle after using the unexpanded fascia flap. Conclusion： ＂Two flap＂ method was easily manipulated and the complications were rare, The reconstructed ears had lucid and three-dimensional contour.
