Thank you for your question and photographs, and I am sorry to see your wound healing difficulties after your tummy tuck. It appears that you have had a number of suture abscesses develop. These are localized areas of infection, that develop as sutures fail to be absorbed completely and cause irritation to the overlying skin. Because the suture material is acting as the cause of the infection, it should be removed, and depending on the size of the wound, a gauze cover or gauze packing applied. These typically then go on to heal without difficulty. Be sure to have close follow up with your surgeon until your healing is complete to insure that no further issues arise.
