Clinical Trial: Study of the Effects of the Pulsed-dye Laser at 585nm and 595nm to Treat Post-operative Scars on Suture-removal Day

Study Status: Completed

Study Type: Interventional

Official Title: Comparison of the Effectiveness of the Pulsed Dye Laser 585nm Versus 595nm in the Treatment of New Surgical Scars

Brief Summary: The purpose of this study is to compare the effects of the pulsed-dye laser (PDL) at two different wavelengths, 585nm and 595nm, in the treatment of post-surgical scars starting on suture-removal day.

Detailed Summary:

Many treatment modalities have been used for the treatment of scars such as dermabrasion, cryotherapy, intralesional corticosteroids, surgical scar revision, and lasers, among others. Previous studies have shown that treatment of scars with the pulsed dye laser (PDL) alone or in combination with other modalities (e.g. corticosteroids, 5-Fluoruracil, silicone sheets) improves the vascularity, pliability, color, and height of hypertrophic scars and keloids. Currently, the PDL has become the laser of choice for the treatment of scars.

To our knowledge, there are no reports in the literature comparing the effects of different wavelengths of the PDL for the treatment of scars. The objective of this study was to compare the effects of the PDL at 585nm vs 595nm in the treatment of postsurgical linear scars starting the day of suture removal.
