I had most surgery several months ago for cancer on my forehead. It resulted in a large hematoma which then caused the scar to heal with an unsightly indentation. My dermatologist recommended a scar revision. Once again, I had a lot of swelling and puckering around the stitching. Why didn't he use intradermal stitching instead? Is the standard practice to stitch on the outside? It seems on the fore head there would be a better method? Should I see a plastic surgeon before this heals?
