  Purpose

Hypothesis: Improvement of recent surgical scars after treatment with 595nm Pulsed dye laser treatments.

Study design: Prospective single blinded within patient controlled randomised trial. Recent surgical scars of at least 5cm will be divided into 2 parts and randomized. 1 part will be treated with 4 595nm Pulsed dye laser treatments on a 4 weeks interval. The other part will serve as a within patient control. 1 and 6 months after the intervention both parts of the scar will be evaluated.

Primary Outcome Measures:
  • Physician global assessment for the treated and control region (PhGA) [ Time Frame: Before start of the study, 1 and 6 months after treatment ] [ Designated as safety issue: No ]
  • Patient global assessment for the treated and control region (PGA) [ Time Frame: Before start of the study, 1 and 6 months after treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Assessment of scar color by colorimetry [ Time Frame: Before start of the study, 1 and 6 months after treatment. ] [ Designated as safety issue: No ]
  • Assessment of scar tickness by ultrasound measurements [ Time Frame: Before start of the study, 1 and 6 months after treatment. ] [ Designated as safety issue: No ]
  • Assessment of viscoelasticity by Cutometer measurements [ Time Frame: Before start of the study, 1 and 6 months after treatment. ] [ Designated as safety issue: No ]
  • Clinical scar assessment by the Vancouver Scar scale and POSAS scale. [ Time Frame: Before the start of the PDL treatment, and 1 and 6 months after the last treatment. ] [ Designated as safety issue: No ]
