Pulsed dye laser in burn scars: Current concepts and future directions

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 pruritis 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.
