Thank you for the photos and your question.This will eventually heal but it will tak its time , good wound care an close contact with your surgeon are very important ! best of luck
The debridement of the dead tissue will allow the body to start healing. As long as the tissues are healthy, you are well nourished, a non-smoker and do proper wound care, this wound will slowly contract and heal. Sometimes a wound vac can speed the process along too. Stick close to your doctor throughout.
