721 Treatment of Hypertrophic Burn and Wound Scars Using a Novel Cold Laser System

Introduction Hypertrophic scars are seen in 70% of individuals after a burn. Survival from acute burns have psychosocial and functional challenges. Hypertrophic scars contain disorganized whorls of collagen, an increase in occluded blood vessels resulting in raised discoloration, inflamed dermis/epidermis and painful sequelae. Management of such scars have been limited to invasive and non-invasive management. One innovative technology is a non-invasive high-intensity laser operating at 1275 nm and 74 Watts, optimizing increased depth of penetration into the tissue utilizing photomechanical effects to biostimulate tissue to heal and regenerate. We present a series of 10 patients. Methods 10 patients were enrolled with hypertrophic scarring secondary to deep partial or full thickness burns. Hypertrophic areas were identified and numerical pain scale, Vancouver Scar Scale and the World Health Organization Quality of Life score were recorded. The non-contact, high-intensity laser was passed over the hypertrophic scars, continuously moving the laser over the entirety of the scar. Each area of hypertrophic scar tissue was lasered for progressively longer sessions, reaching a therapeutic time of 10 min in each section. Results Patients were utilizing previously known non-invasive therapies for scar reduction, such as, compression garments, scar treatment ointments, as well as steroid injection and non-medical therapies such as acupuncture. In our series, 90% of the patients reported decrease in scar pain, inflammation, pigmentation and improved pliability by the second treatment. Decreased scar height was identified by the eighth session, where conventional protocols could require months to years before any changes were observed. Changes in the scars were even identified after the normal time period identified for maximal improvement using conventional burn therapies. In a survey presented to patient, even pain was improved, identified with reduction in narcotic/NSAID use in patients undergoing the therapies. Conclusions Non-invasive high-intensity laser therapies are useful adjuncts for reduction of hypertrophic burn scars. Our case series presents a treatment option in patients that have functional, physical and cosmetic challenges. We anticipate broader applications for hypertrophic burn scar reduction utilizing adjunctive non-invasive laser therapy, reducing the need for invasive scar revision and limiting psychosocial strain. Applicability of Research to Practice In this case series, non-invasive high-intensity laser therapy provided timely decrease in hypertrophic scar characteristics in an outpatient setting. Thus, leading to decrease in invasive operative therapy and overall improvement in quality of life. Further studies are needed to elucidate other benefits and utility of the laser and possible evaluation of keloid scars.
