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 description

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.

Interventions

Type	Name	Description
PROCEDURE	PDL 450 microseconds	The scar will be randomly divided into three equal fields. One third of the scar will receive PDL 585 nm using a 7 mm spot size at 4.0 J (Joules) for 450 microseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
PROCEDURE	PDL 1.5 milliseconds	The scar will be randomly divided into three equal fields. One third of the scar will receive PDL 585 nm using a 7 mm spot size at 4.0 J (Joules) for 1.5 milliseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
