Usually, if a scar is formed for more than 1 year, the effect of medication and other treatments is limited, while a scar that has been formed for many years usually requires surgery.
The specific surgical procedure needs to be chosen according to the specific situation of the scar and the surrounding normal skin. In general, surgery can basically remove the scar and achieve the effect of restoring function and aesthetics.
The commonly used surgical methods include scar release and reshaping, scar excision and skin grafting, local reshaping, expander surgery, flap surgery, grinding cell dispersion surgery, etc. It is very important to choose the appropriate surgical method individually.
