Low level lasers are low power lasers which have biostimulatory effects on wounds when exposed for short duration and energy. The bio-stimulatory effects of low level laser therapy (LLLT) have been found to be effective as adjuvant therapy to accelerate wound healing. It augments tissue repair and regeneration along with its anti inflammatory and analgesic effects. This property of low level lasers can be used effectively for burn wound bed preparation as an adjuvant therapy. A 30 year female with old and infected thermal burns, measuring 15% of total body surface area was treated with Low level gallium arsenite Laser. Wound was debrided and LLLT was given for 10 minutes along entire raw area at weekly intervals for 3 sittings following which split skin grafting was done. It was notice that wound healing was enhanced, graft was taken successfully and no complications were noted. Through this article we would like to highlight the use of LLLT as an adjuvant therapy in burn wound healing.
