Update in scar revision.

Scar revision is indicated in certain situations for cosmetic and functional reasons. Improvement is not feasible with all scars; expectations must be tempered and realistic goals set. There is no generic approach to timing or technique in scar revision. Certain scars will benefit from revision at 6 to 12 months after the inciting traumatic event; others from much earlier intervention. Most scars will show degrees of improvement for up to 1 year. Many scars, however, may benefit from earlier treatment, including dermabrasion. The decision to revise a scar must be reached by patient and surgeon, with realistic expectations and the end-point clearly established. The simplest and most direct approach. should then be taken to reach this goal.
