Early Management of Scars Using a 532-nm Nd:YAG Laser
Background Laser therapy is generally postponed until scar maturation. We speculated that the use of laser therapy at the beginning of the wound healing process might minimize discomfort and problems at an early stage. Methods From January 2013 to May 2014, we conducted a study of 50 patients who un...

We speculated that the use of laser therapy at the beginning of the wound healing process might minimize discomfort and problems at an early stage. Methods From January 2013 to May 2014, we conducted a study of 50 patients who underwent primary closure or scar revision procedures due to facial scarring. Within 1 to 2 weeks after the removal of all stitches, we performed laser treatments with a 532-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser. To assess the improvement of the scars, we evaluated the scars using the Vancouver Scar Scale (VSS) and conducted a photo analysis using a computer graphics program. Results The mean score on the VSS decreased from 5.99 to 1.49 after the laser treatment. The score for each evaluation item decreased, meaning that the scars improved. The differences showed statistical significance. In the photo analysis that was conducted using Adobe Photoshop, the mean brightness of the pixels located within the scar territory increased from 61.54% to 69.42% after laser treatment, and the mean chroma decreased from 50.65% to 43.12%. These changes were statistically significant. Conclusions We used a 532-nm Nd:YAG laser at an early stage of scar formation and confirmed improvements in the redness, hyperpigmentation, and hypertrophy of the scars shortly after treatment.http://e-aaps.org/upload/pdf/aaps-23-62.pdfcicatrixlaser therapylasers |
