Abstract
There is a wide spectrum of cutaneous scarring ranging from mature linear scars to abnormal raised and widespread hypertrophic scars as well as major keloids. Keloids are sequelae of abnormal wound-healing process. They are a common reason for dermatologic consultation owing to pruritus, pain, restriction in movement and cosmetic disfigurement.Various treatment modalities are available for keloid; intralesionalcorticosteroids, topical applications, cryotherapy, surgery, laser therapy, pressure therapy, and silicone sheeting are options that havebeen extensively used. Also, the side effects of various treatmentmodalities such as dyspigmentation, atrophy and high recurrence rateare considered a significant limitation. Once medical lasers were proven to be effective for scars, researches have been proceeded mainly on the basis of two premises: the comparative effectiveness among lasers, and laser therapy as a preventivemeasure.The therapeutic use of lasers with different wavelengths has beeninvestigated. The neodymium: YAG laser (1064nm), flash lamppumped pulsed dye laser (PDL) (585-595 nm); carbon dioxide laser (CO2) (10,600 nm) and argon laser (488 nm) were frequently used in the treatment of raised scars.
