皮肤瓣状伤口或损伤在急诊外伤中很常见，但其定义、分类和修复方法却少有文献记载。人体在斜形外力作用下，皮肤软组织连续性中断，形成一边带蒂、其余各边的组织与基底分离的伤口，因外观与整形手术设计的局部皮瓣相似，故统称为瓣状伤口。根据瓣状伤口形状，可细分为三角形瓣状、U形瓣状和不规则瓣状伤口；根据皮瓣的血供方向，可分为逆行瓣状伤口和顺行瓣状伤口；根据发生机制，可分为切割型瓣状伤口、挫裂型瓣状伤口和撕裂型瓣状伤口。瓣状伤口大多形态不规则，血运比较差。对于这类伤口，如果简单地行清创缝合，瓣部极易缺血坏死。或因创部后期瘢痕增生挛缩影响美观。本文对急诊皮肤瓣状伤口进行系统总结，并对其整复方法予以探讨。

Skin flap-like wounds or injuries are common in emergency trauma, but relevant research papers rarely report the definition, classification and their repair methods. A flap-like wound refers to the discontinuity and damage of the structure of superficial soft tissue caused by oblique external forces, with the appearance that one side of the tissue connected to the base of the wound by a pedicle and the rest sides detached, which is similar to a local skin flap designed in general plastic surgery. Depending on the shapes, flap-like wounds can be subdivided into triangle, U-shaped and erose flap-like wounds. Besides, they can be divided into reverse flap-like wounds and anterograde flap-like wounds according to the direction of blood supply of the flaps. And in accordance with the cause of the wounds, flap-like wounds are composed of incised flap-like wounds, contused flap-like wounds and lacerated flap-like wounds. Most flap-like wounds are irregular in shape with poor blood supply. These flaps of wounds are prone to avascular necrosis if wounds are debrided and sutured simply, and the scar hyperplasia and contracture of the wound surfaces will not avoid affecting the appearance. In this article, the authors expound the definition of common flap-like wounds and their repairing methods systematically.
