Hypertrophic scarring after partial-thickness burns is common, resulting in raised, erythematous, pruritic, and contracted scars. Treatment of hypertrophic scars, especially on the face, is challenging and has high failure rates. Excisional treatment has morbidity and can create iatrogenic deformities. After an extensive experience over 10 years with laser therapy for the treatment of difficult scars, the pulsed dye laser (PDL) has emerged as a successful alternative to excision in patients with hypertrophic burn scars. Multiple studies have shown its ability to decrease scar erythema and thickness while significantly decreasing pruritus and improving the cosmetic appearance of the scar. The history of laser therapy and the mechanism of action and results of the PDL in burn scars will be reviewed. The PDL should become an integral part of the management of burn scarring and will significantly decrease the need for excisional surgery.
部分厚度烧伤后的增生性瘢痕很常见，导致凸起、红斑、瘙痒和收缩的瘢痕。增生性瘢痕的治疗，尤其是面部的治疗具有挑战性，且失败率很高。切除治疗有发病率，并且可能会导致医源性畸形。在广泛的 10 多年激光治疗困难性瘢痕的经验之后，脉冲染料激光（PDL）已经成为增生性烧伤瘢痕切除的成功替代方法。多项研究表明，它能够减少瘢痕的红斑和厚度，同时显著减少瘙痒并改善瘢痕的美观外观。本文将回顾激光治疗的历史以及 PDL 在烧伤瘢痕中的作用机制和结果。PDL 应该成为烧伤瘢痕管理的一个组成部分，这将显著减少切除手术的需求。
