Surgery can be considered if you have a poor scar that has resulted from a traumatic injury or a surgical wound that became either infected or come apart and the wound left open to heal. In such cases, ‘scar revision’ where the original scar is removed and closed with plastic surgery techniques may be effective in improving the quality of the scar. Following the revision, the scar may be neater and have a better appearance but there will still be a permanent scar which is usually about the same length or slightly longer than the original poor scar.
In cases where there was no particular cause for the poor scar such as wound infection or dehiscence, there is a high risk of recurrence of the hypertrophic, keloid or stretched scar following scar revision.
When a lumpy keloid scar is removed, steroid may be injected into the wound to dampen down the scarring to try and prevent the keloid scar from reforming. The injections may be need to be repeated every 4 to 6 weeks.
