Comparison of the effectiveness of the pulsed dye laser 585 nm versus 595 nm in the treatment of new surgical scars

Abstract

after laser irradiation, the treated sections were more similar to a non-scarring process than the control. Cosmetic outcome: visual analog scales increased in all groups (P < 0.05), but the greatest increases were observed in the 585 nm and 595 nm laser-treated groups (50% and 60%, respectively) compared with controls (30%). There were significantly higher scores with the lasers than for the control (P < 0.001) at each visit after baseline. Both the 585 nm and 595 nm PDL treatments were effective in improving the appearance and normalizing the vascularity and pliability of post-operative scars. Both wavelengths improved the scars' visual appearance more than controls. We found that 585 nm appears to be the preferred wavelength, as it substantially normalized the height in addition to the vascularity and pliability in a significant number of scars.

Nonablative Fractional Laser Resurfacing for the Treatment of Hypertrophic Scars: A Randomized Controlled Trial

“…9,30,31 Although this study was not powered to examine differences between older and younger scars, we found that the PhGA of four of five scars younger than 6 months had greater improvement of the treated side than of the untreated control side at 3-month follow up. 9,30,31 Although this study was not powered to examine differences between older and younger scars, we found that the PhGA of four of five scars younger than 6 months had greater improvement of the treated side than of the untreated control side at 3-month follow up.…”

Treatment of Surgical Scars Using a 595-nm Pulsed Dye Laser Using Purpuric and Nonpurpuric Parameters: A Comparative Study

“…[22][23][24] At the final evaluation visit, there was a trend toward a significant difference between groups in VSS total score, with the nonpurpuric segments rated as better than the other conditions, although all scar segments improved over time, whether treated or not, when evaluated using global cosmetic ratings. Although this may seem surprising, it confirms the results of several other studies that used PDL with lowerenergy nonpurpuric parameters and showed significant improvements in scar appearance.…”

A prospective, randomized controlled trial on the efficacy of fractional photothermolysis on scar remodeling

“…Several studies have evaluated intervention for scar remodeling starting as early as 2 weeks after the surgical procedure [4,26]. Thus, further prospective studies are warranted to decipher if there is an optimal time to improve scar remodeling.…”
