Surgical correction is used for hyertrophic scars, (excessive scar tissue growth in the region of a wound), which are considered cosmetically disfiguring or cause disrupted functioning.  The scar tissue is removed and the incision sutured again or closed by means of a skin transplant.

The surgical correction of scars should only be carried out once the scar has “died down” i.e. reached a stable condition.
The surgical correction of keloids, (excessive scar tissue growth spreading beyond the region of a wound), is problematic as keloids frequently recur after removal. Therefore the surgical removal of keloid tissue is often combined with radiation treatment or compression treatment, started immediately following the operation. The local application of glucocorticoids and taking vitamin A can also help prevent the recurrence of keloids.
