How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Single Group Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Keloidal scar
Randomly assigned keloid scar to each intervention (IL KA)
Long-pulse ND YAG and Erbium YAG laser device: Fotona Dynamis
Experimental: Keloidal scar 2
Randomly assigned keloid scar to each intervention (IL KA + ND YAG)
Intralesional corticosteroid injection combine with long-pulse Neodynium-doped Yttrium Aluminium Garnet Laser (Nd-YAG) (IL KA + ND YAG)
Experimental: Keloidal scar 3
Randomly assigned keloid scar to each intervention (ILKA + Er YAG)
Intralesional corticosteroid injection combine with Erbium Yttrium Aluminium Garnet Laser (Er-YAG) (IL KA + Er YAG)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Vancouver scar scale
Time Frame: 5 months
Vancouver scar scale to evaluate scar severity of keloid scar assessing 4 variations including vascularity, pigmentation, pliability, height scoring range from 0-13 (the more scores resembling the more severity)
5 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Japan Scar Workshop Scar Scale
Time Frame: 5 months

Japan Scar Workshop Scar Scale to evaluate scar severity of keloid scar assessing 2 main domains (risk factors and presenting symptoms) by 2 tables

  1. Classification scoring range 0-5 = matured scars 6-15 = hypertrophic scars 16-25 = keloids
  2. Evaluation for treatment & follow ups scoring range from 0-18 (the more scores resembling the more severity)
5 months
