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.
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.
