Scars can hurt, itch, and make people feel uncomfortable. Contractures can also limit mobility. It may also be challenging to integrate patients with hypertrophic scars into a culture that has come to value welfare, individuality, and outward attractiveness more and more. Aim: to research the healing potential of pulsed high intensity laser therapy in situations with hypertrophic scarring following burns. Subjects and Methods: From Cairo University Hospitals, 40 patients—40 men and 40 women—with hypertrophic scars and ages ranging from 20 to 45 were chosen. Pulsed high intensity laser therapy together with conventional therapy will be administered to Group (A), the study group. The controlled members of Group (B) receive conventional therapy. Ultrasonography and the Vancouver Scar Scale were used to evaluate the patients. Results: Both traditional therapy (deep friction massage) and high intensity laser therapy had a substantial therapeutic effect in the management of post-burn hypertrophic scar, however high intensity laser therapy generated better improvements in scar thickness and cosmetic appearance. Conclusion: High-intensity laser therapy works well for treating post-burn hypertrophic scars.
