Treatment of a Pigmented Hypertrophic Scar by Low-Level Laser Therapy (LLLT): a Case Report

A hypertrophic scar is defined as an excess healing response that is a dilemma forphysicians. Several therapies are available: intralesional corticosteroids, topicaltreatments, cryotherapy, surgery, radiation, silicone gel dressing and laser therapy.Pulsed-dye, Nd-Yag and CO2 lasers have been used for treatment of keloids andhypertrophic scars but recurrence is common. Recently Low-Level Laser Therapy(aluminum-gallium-arsenide (AlGaAs) Diode 980nm, red light (Mustung, KLO4,Helium Neon 630 nm) and blue light LED lasers have been used for closure ofwounds. The aim of this report is to show the effectiveness of these lasers for thetreatment of a hypertrophic scar on the forearm of a 40 year-old woman due toburning by gas explosion.
