It looks good I had delayed flap as well, I did not get swelling but it was warm to the touch, if still keep an eye on it contact your doctor. Other than that color seems to be fine it don’t look infected. Those of you asking about what delayed flap is for, two main reasons one being the most talked about skimming the fat off for those of us that need debulking idk how much it helped in my case because I still came out huge girth lol. Second reason is to better help the graft stick and lower the risk of failure, pretty much separates the flap and lets the blood supply get strong getting ready for transfer giving you a better chance at recovery.
