Background: Despite many advances in conventional wound care, the treatment of complex persistentlesions continues to be problematic with regard to effective healing. Whether they are aggravated by chronicillnesses, compliance issues or inappropriate would care practices, many patients suffer from recalcitrant lesions.Laser Therapy has been proven to be highly effective in resolving these wounds and has been documented toaccelerate wound healing and tissue repair.Purpose: To evaluate and document the progress of patients with intractable wounds previously treatedby traditional methods, including topical applications, antibiotics, dressings, etc. Measurements includecircumference and depth of wound, rate of healing and visual pain analogue.Methods: Patients with complex wounds including peripheral arterial occlusive disease, diabetes, postsurgicalwounds, osteomyelitis, and infected post-surgical incisions were evaluated and photographed before,during and at the conclusion of Laser Therapy. The protocol consisted of the application of a red (660 nm) lightemittingdiode (LED) array (750 mW, 10 mW/cm2), infrared (840 nm) LED array (1500 mW, 20 mW/cm2), redlaser (660 nm, 75 mW, 750 mW/cm2) and infrared laser (830 nm, 180 mW, 1800 mW/cm2).Results: Wounds that were enlarging or unresponsive to prolonged periods of conventional wound caredemonstrated a significant response to Laser Therapy in terms of neovascularization, marginal epithelialization,granulation and collagen formation at an accelerated rate.Conclusion: Laser Therapy is a specific approach leading to the resolution of the inflammatory processand thereby enhancing healing, even with the most problematic lesions.
