Pulsed dye laser versus long-pulsed Nd:YAG laser in the treatment of hypertrophic scars and keloid: A comparative randomized split-scar trial.

Introduction: Keloids and hypertrophic scars are benign fibrous growths that occur after trauma or wounding of the skin and present a major therapeutic problem.

Objective: The purpose of this study is to evaluate and compare the effectiveness of pulsed dye laser (PDL) versus Nd:YAG laser in hypertrophic scar and keloid.

Methods: Twenty patients with hypertrophic scars and keloid were included in this prospective, randomized, split-scar study.
