Scar revision surgery is meant to minimize the scar so that it is more consistent with your surrounding skin tone and texture. Medications are administered for your comfort during the surgical procedures. The choices include local anesthesia, intravenous sedation and general anesthesia. Your doctor will recommend the best choice for you. The degree of improvement that can be achieved with scar revision will depend on the severity of your scarring, and the type, size and location of the scar.
