Scar revision is performed to reduce the appearance of scars caused by injury or previous surgery. Scars are by definition permanent, but surgery can narrow, fade and otherwise reduce the appearance of severe or unattractive scarring, which is especially helpful in areas of cosmetic importance such as the face and hands.
There are many surgical methods of scar revision, only some of which may be appropriate for a particular type of scar or its location. These include surgical excision, skin grafts, flap surgery and Z-plasty (repositioning a scar so that it aligns with the face and is less noticeable). The effectiveness of scar reduction depends on a number of factors, including the nature of the injury, your body’s healing mechanism, the size and depth of the wound, how much blood supplies the area and the thickness and color of your skin.
