Outcome Measures

Primary Outcomes (2)

  • Patient and Observer Scar Assessment Scale (POSAS) scores

    The observer scale of the POSAS consists of six items (vascularity, pigmentation, thickness, relief, pliability and surface area). All items are scored on a scale ranging from 1 ('like normal skin') to 10 ('worst scar imaginable'). The sum of the six items results in a total score of the POSAS observer scale. Categories boxes are added for each item. Furthermore, an overall opinion is scored on a scale ranging from 1 to 10. All parameters should preferably be compared to normal skin on a comparable anatomic location. comparable anatomic location.

    once every 3 months for 1 year after the last treatment

  • Vancouver Scar Scale (VSS) scores

    Physician evaluation comprised the use of the Vancouver Scar Scale (VSS) to evaluate the pigmentation (0=normal, 1=hypopigmented, 2=hyperpigmented), pliability (0=normal, 1= supple, 2=yielding, 3=firm, 4=banding, 5=contracture), height (0= flat, 1=5 mm), and vascularity (0=normal, 1=pink, 2=pink to red, 3=red, 4=red to purple, 5=purple).

    once every 3 months for 1 year after the last treatment
