Can Hypertrophic Scars Return After Cutting Them Out? (photo)

I would treat these hypertrophic and potentially keloid scars on the back and chest with a combination of IIT, laser, and pressure, coupled with topical silicone. 

The simple answer to your question is that it is possible for hypertrophic scars to come back after surgically removing them.  The area of the body where the scar is located can influence the risk of them returning as well as the way the incision is closed.  Sometimes an injection of a steroid (an anti-inflammatory) into the area at the time of excision and/or afterwards can help reduce the chances of the hypertrophic scar returning as well.    

Hypertrophic scars which you have can return after excision. It is always best to at least try a time or two with steroid injections to help them settle down. If this is no help them I turn to surgery. The newest treatment for the scars is a laser called Lumenis Encore Ultrapulse with an attachment called ScaarFX. This gives an optimal ablating and smoothing ratio so that it softens the scar. It often takes a few times to minimize the scar as much as possible. Unfortunately it never possible to erase the scars. Good luck!
