耳后“旋转门”岛状皮瓣在Ⅰ期修复耳甲缺损中的应用

Postauricular ＂revolving door＂ flap in one stage reconstruction of concha defect

目的探讨耳后“旋转门”岛状皮瓣Ⅰ期修复耳甲内皮肤组织缺损的方法及疗效。方法利用耳后“旋转门”中央蒂岛状皮瓣I期修复耳甲内组织缺损，最小面积为1．0cm×1．3cm，最大面积为2．7cm×3．0cm。结果15例术后岛状皮瓣均存活良好，经6个月至5年随访，耳廓外形均较满意。结论耳后“旋转门”岛状皮瓣血供可靠，形态、色泽、质地与周围正常组织一致，供瓣区隐蔽，是修复耳甲软组织缺损修复的最佳术式之一。

Objective To study the technique of using the postauricular ＂revolving door＂ island flap in one-stage reconstruction of concha defect and its efficacy. Methods Fifteen cases of concha de-fect were repaired by the postauricular ＂revolving door＂ island flap in one stage reconstruction from 2000-2010. The maximum size of defect was 2. 7 cm × 3. 0 cm, and the minimum was 1. 0 cm ×1.3 cm. Results All the island flaps were survived postoperatively, and satisfactory in auricular ap-pearances of all patients by 6 months to 5 years follow-up. Conclusions The ＂revolving door＂ island flaps with abundant blood supply are transferred to reach the auricular defect, which match normal au ricular tissue in contour, color, and texture. This flap on the retroauricular area is relatively con cealed, and it therefore can be one of the best procedures for repair of the auricular defects, especially concha.
