Hypertrophic scars are often confused with keloids, since both tend to be thick, red,
and raised. Hypertrophic scars, however, remain within the boundaries of the original incision or wound. They often improve on their
own-though it may take a year or more-or with the help of steroid applications or injections.
This hypertrophic scar has formed a
contracture, restricting finger motion.
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
With Z-plasty, the scar is removed
and several incisions are made on
each side, creating small triangular
flaps of skin. Then the flaps are
rearranged and interlocked to cover
the affected area.
The incision is closed with a Z-shaped
line of sutures. The new scar should be thinner
and less visable, and allows the finger
to be extended.
After scar revision
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.
As you heal, keep in mind that no scar can be removed completely; the degree of improvement depends on the size and direction of your scar, the nature and quality of your skin, and how well you care for the wound after the operation. If your scar looks worse at first, don't panic-the final results of your surgery may not be apparent for a year or more.
