AbstractLow level laser therapy (LLLT) has been used in different fields, including healing of chronic ulcers like diabetic and pressure ulcers. Here we are using this method to look for role in FTSG donor site. Full thickness skin grafts include full thickness of the epidermis and dermis whereas split thickness skin grafts (STSG) include the entire epidermis and only partial dermis. LLLT improves tissue perfusion and fibroblast proliferation, with increases in collagen synthesis accelerating wound healing. The purpose of this case report is introducing LLLT as a therapeutic method for accelerating healing of FTSG donor site.
