Can an Indented Scar on the Scalp Be Excised to Be at Least Flat? (photo)

Some traumatic scars, and even some surgical scars, heal with the underlying muscle contracting away from the wound and this can create elevations next to the wound and and indentation in the scar (although there are other causes of this too). Wounds mature and often look better with time. This could take more than a year after the wound was created. Surgical revision may have to revise the underlying infrastructure as well as the skin. Many doctors will also follow surgical revision, about 2 months later, with Fraxel laser resurfacing to improve the result furher. There is a risk that the surgical revision would not only produce a lack of imiprovement, ,but the surgeon can't gurantee that there will be improvement. Sometimes it makes sense to revise a small segment of the scar and see how it heals prior to doing the whole residual scar.

You need to have revision after 6 months. You can try topical silicone gel and mederma for now.
