A burn of the oral commissure is one of the most common types of electrical injury in children. To minimize postoperative wound contracture in late reconstructive surgery, a functional reconstruction that combines excision of the burn scar with lateral advancement of the orbicularis oris muscle, re-creation of the modiolus labii, and reestablishment of vermilion continuity has been developed. Functional restoration of the labial musculature to the preinjury position with re-creation of the modiolus labii and reestablishment of vermilion continuity appears to significantly decrease the amount of postoperative wound contracture (p less than 0.025).
口角烧伤是儿童最常见的电损伤类型之一。为了在晚期重建手术中尽量减少术后伤口挛缩，已经开发出一种功能性重建方法，即将烧伤瘢痕切除与口轮匝肌侧向推进、重建唇结节以及重建唇红连续性相结合。通过重建唇结节和重建唇红连续性，将唇部肌肉组织功能恢复到伤前位置，似乎能显著减少术后伤口挛缩的程度（p小于0.025）。
