易位扩张皮瓣在面颊部皮肤缺损修复中的设计与应用

目的 总结易位扩张皮瓣在修复面颊部皮肤缺损中的设计方法及应用.方法 将扩张的易位皮瓣分为单纯易位扩张皮瓣、易位-推进-易位扩张皮瓣和旋转-推进-易位扩张皮瓣3种.对135例面颊部血管瘤、瘢痕、色素痣患者,根据其皮肤缺损的形态、位置,应用此3种易位扩张皮瓣修复.单纯易位扩张皮瓣若长宽比例大于2:1,则需行延迟术.结果 本组共形成139个易位扩张皮瓣,其中单纯易位扩张皮瓣17个(皮瓣延迟15例).易位-推进-易位扩张皮瓣69个,旋转-推进-易位扩张皮瓣53个.有6个易位扩张皮瓣出现远端血运障碍(0.5～2 cm),其中单纯易位扩张皮瓣2个,其他类型易位扩张皮瓣4个.其余皮瓣良好,修复效果满意.结论 对于颊部皮肤缺损的修复,根据缺损的形态和位置恰当地设计应用各种易位扩张皮瓣修复.可获得良好的效果.

Design and application of the expanded transposition flaps In the treatment of cheek skin defects

Objective To introduce the design and application of the expanded transposition skin flap in the treatment of cheek skin defects. Methods The expanded transposition flaps were divided into three types: the regular expanded transposition flap (ERT flap), the expanded transposition-advancement-transposition flap (TAT flap) and the expanded rotation-advancement-transposition flap (RAT flap). 135 cases of cheek skin defects resulted from hemangioma, scar and naevi were treated with these three types of flaps. Delay surgery was needed when the ratio of length to width was bigger than 2:1. Results There were 139 expanded transposition flaps, including 17 ERT flaps, 69 TAT flaps, 53 RAT flaps. Blood supply disturbance was happened at the end of the flaps in 6 cases, including 2 ERT flaps and 4 other flaps. Other flaps had no complication. The results were satisfactory. Conclusions The expanded transposition skin flap is a reliable method to repair the cheek skin defect. The preoperative flap design is very important for successful reconstruction.
