Background. The treatment of scars caused by burn is a difficult challenge in developing countries that includes enormous treatment cost. Burn scars tend to get worse with hypertrophy and contracture, leading to limitations of function. This study aimed to compare the efficacy oflow-level laser therapy (LLLT) to therapeutic ultrasound (US) on hypertrophic scar in pediatric burns. Methods. 45 children participated in the study, their age ranges from 12 to 15 years of age, suffering from hypertrophic scars. Each scar divided to 2 identical halves. One half received (LLLT) with deep friction massage and the other received therapeutic ultrasound with deep friction massage. Participants were assessed pre & post two months of study by Ultrasonography and Vancouver Scar Scale. Results. Significant improvement was reported in both halves of scar but laser was more effective in decreasing scar height, and lowering Vancouver scale score (p < 0.0001). Conclusion. LLLT and US are proficient and secure modalities for post-burn hypertrophic scars treatment in children.
