The Effectiveness of Early Combined CO2 Ablative Fractional Laser and 595-nm Pulsed Dye Laser Treatment After Scar Revision

Scars are significant complications of wound healing and associated with negative physical, psychological, and cosmetic effects. Scar revision and laser treatment have been used over the past century to improve many different types of scars. Here, we evaluated the effectiveness of early combined carbon dioxide ablative fractional laser (AFL) and pulsed dye laser (PDL) treatment after scar revision. Fourteen patients who underwent scar revision were enrolled. All patients were treated with both a 10,600-nm AFL and a 595-nm PDL commencing 2 weeks after scar revision and continuing at 4-week intervals for a total of 4 treatments. Vancouver Scar Scale scores were evaluated before treatment and 5 months after the final treatment. All Vancouver Scar Scale scores improved significantly except that of scar height. We encountered no adverse complications (wound disruption, or hyper- or hypopigmentation) during follow-up. Early combined carbon dioxide AFL and PDL treatment after scar revision effectively and safely minimized scar formation.
