Nineteen patients with 19 burn scars were treated with a 400 mW 670 nm laser twice a week over 8 weeks. In each patient a control area was defined, that was not irradiated. Parameters assessed were the Vancouver Scar Scale (VSS) for macroscopic evaluation and the Visual Analogue Scale (VAS) for pruritus and pain. Photographical and clinical assessments were recorded in all the patients. Seventeen out of 19 scars exhibited an improvement after treatment. The average rating on the VSS decreased from 7.10±2.13 to 4.68±2.05 points in the treated areas, whereas the VSS in the control areas decreased from 6.10±2.86 to 5.88±2.72. A correlation between scar duration and improvement through laser could be found. No negative effects were reported.
