Scar Revision in Bay Area, San Francisco

Scars - whether they're caused by accidents or by surgery - are unpredictable. The way a scar develops depends as much on how your body heals as it does on the original injury or on the surgeon's skills.

While no scar can be removed completely, plastic surgeon Dr. Roy Kim can often improve the appearance of a scar, making it less obvious through the injection or application of certain steroid medications or through surgical procedures known as scar revisions.

If a conservative approach doesn't appear to be effective, hypertrophic scars can often be improved surgically. The plastic surgeon will remove excess scar tissue, and may reposition the incision so that it heals in a less visible pattern. This surgery may be done under local or general anesthesia, depending on the scar's location and what you and your surgeon decide. You may receive steroid injections during surgery and at intervals for up to two years afterward to prevent the thick scar from reforming.

Correcting a contracture usually involves cutting out the scar and replacing it with a skin graft or a flap. In some cases a procedure known as Z-plasty may be used. And new techniques, such as tissue expansion, are playing an increasingly important role. If the contracture has existed for some time, you may need physical therapy after surgery to restore full function.

Because of its location, a facial scar is frequently considered a cosmetic problem, whether or not it is hypertrophic. There are several ways to make a facial scar less noticeable. Often it is simply cut out and closed with tiny stitches, leaving a thinner, less noticeable scar. Some facial scars can be softened using a technique called dermabrasion, a controlled scraping of the top layers of the skin using a hand-held, high-speed rotary wheel. Dermabrasion leaves a smoother surface to the skin, but it won't completely erase the scar.

Grafting involves the transfer of skin from a healthy part of the body (the donor site) to cover the injured area. The graft is said to "take"when new blood vessels and scar tissue form in the injured area. While most grafts from a person's own skin are successful, sometimes the graft doesn't take. In addition, all grafts leave some scarring at the donor and recipient sites.

Flap surgery is a complex procedure in which skin, along with the underlying fat, blood vessels, and sometimes the muscle, is moved from a healthy part of the body to the injured site. In some flaps, the blood supply remains attached at one end to the donor site; in others, the blood vessels in the flap are reattached to vessels at the new site using microvascular surgery.

Skin grafting and flap surgery can greatly improve the function of a scarred area. The cosmetic results may be less satisfactory, since the transferred skin may not precisely match the color and texture of the surrounding skin. In general, flap surgery produces better cosmetic results than skin grafts.

With any kind or scar revision, it's very important to follow your surgeon's instructions after surgery to make sure the wound heals properly. Although you may be up and about very quickly, your surgeon will advise you on gradually resuming your normal activities.
