After an injury, burns or operation, or else as a result of tissue damage from some illness, scar tissue always forms. Overall, there is no need to operate on scars that are a little stretched or irregular, except for instances in which it is possible to significantly improve their appearance. In such cases, scar correction is considered to be cosmetic.
Sometimes, scars can be extremely deforming, because of their location or development. They can impair limb movements, cause pain, undermine the functioning of adjoining organs, ulcerate or bleed, or form keloids (keloids are scars that are markedly raised and overgrown). In such instances, correction of the scar is considered to be reconstructive. Even though the overall appearance of the scar often improves after such operations, the main reason for the correction of such scars is not cosmetic, but rather because of the subsequent improvement in functions.
The operation is carried out under a local anaesthetic and the patient remains in hospital for a couple of hours after the operation.
