An interventional study of Triamcinolone acetonide injection and Fotona dynamis: Long pulse Nd YAG + Er YAG laser in Hypertrophic Scar, Keloid and Laser, sponsored by Somdech Phra Nangchao Sirikit Hospital. Completed at 1 site in Thailand. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-12-04.
Sponsored by Somdech Phra Nangchao Sirikit Hospital · Not applicable, Interventional, and Treatment
To compare the effectiveness of hypertrophic or keloid scar treatment with either intralesional corticosteroid injection alone or combined intralesional corticosteroid injection with either long-pulse ND YAG or Erbium YAG
Exclusion Criteria:
Randomly assigned keloid scar to each intervention (IL KA)
Drug: Triamcinolone acetonide injection
Randomly assigned keloid scar to each intervention (IL KA + ND YAG)
Device: Fotona dynamis: Long pulse Nd YAG + Er YAG laser
Randomly assigned keloid scar to each intervention (ILKA + Er YAG)
Device: Fotona Dynamis: Long pulse Nd YAG + Er YAG laser
Long-pulse ND YAG and Erbium YAG laser device: Fotona Dynamis
Intralesional corticosteroid injection combine with long-pulse Neodynium-doped Yttrium Aluminium Garnet Laser (Nd-YAG) (IL KA + ND YAG)
Intralesional corticosteroid injection combine with Erbium Yttrium Aluminium Garnet Laser (Er-YAG) (IL KA + Er YAG)
Vancouver scar scale
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)
Time frame: 5 months
Japan Scar Workshop Scar Scale
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)
Time frame: 5 months
Plan to share: Yes — Patient demographic data and scar characteristics, severity can be shared upon requests
