Automobile accidents, dog bites, and other injuries can cause obvious scars. These scars can often be improved by revision surgery using plastic surgical techniques. Realigning the scar along natural lines, narrowing the scar, or flattening it are some of the methods utilized in scar improvement. In addition, methods of dermabrasion (derm-uh-BRAY-shun), sanding, and resurfacing, using a CO2 laser may also be used. Sometimes no specific surgical treatment is advised for a scar. This is especially true when the injury has been recent and not enough time has been allowed to achieve the optimal final appearance. In general, most scars, depending on the body part, require a period of up to eighteen months for full maturation (match-UR-ration). For more information on scar correction, contact a cosmetic or plastic surgeon.
