What is involved in revising a scar?

Excision: Scar revision usually involves excising the scar and re-closing the area in layers. Deep sutures are typically used to provide dermal support which minimizes scarring. Also, depending on the location and orientation of the scar, the surgeon may decide to perform local tissue rearrangement (such as a z-plasty) to better conceal a scar. Post-operative scar management is also important.

Excising scar: Typically, the old unsightly scar is completely excised (surgically removed), the wound is then meticulously closed and at times, re-oriented and closed to allow better healing.

Varies: Depends on scar location, size, character, cause, etc. Revisions start at mechanical dermabrasion for surface irregularities and go to excision of the old scars and repairing them. Some scars require both reduction and redirection of their axis in order to approach the "natural skin tension lines" of the body. Some remodeling of scars can be accomplished with certain laser treatments.

Excision and closure: When revising a scar, it is excised an then reclosed.

Scar revision: Involves cutting out the old scar, releasing underlying scar tissue, and carefully re-stitching it back together. Sometimes, plastic surgery techniques called "z-plasty" or "w-plasty" are used, but that's more than i can explain here. Best to see your local board-certified plastic surgeon to discuss more.
