From the submitted photo, it does not appear that there is any necrosis after tummy tuck. There is some dried blood at the skin edges which will wash away over time, but the skin all appears healthy.
You have a little swelling, which is normal and your body is already starting to form scar tissue, which is also normal. Ask your surgeon for scar care recommendations to optimize your healing. My patients massage with oily lotion to soften the scar tissue. (Emily J. Kirby, MD, Fort Worth Plastic Surgeon)
Actually, the repair looks well without obvious signs of necrosis. One thing about revisions is they are more successful because the blood supply to the tissue is robust as compared to when the tummy tuck is done. Also less tension. (Joel Patrick Maier, MD, Cincinnati Plastic Surgeon)
The photos do not appear to show any necrosis, but make sure you follow up with your surgeon throughout this entire healing process.
Scars take a long time to mature so ask for ways to minimize the scar on a long-term basis. Below is a fully healed tummy tuck result. (Francisco Canales, MD, Santa Rosa Plastic Surgeon)
Your concerns are understandable but the photographs do not demonstrate any areas of necrosis. Typically, the area of the incision line that has the most difficulty with healing is the junction of the vertical and horizontal incisions; this has to do with blood flow reaching the area.
At this point, you seem to be doing well; continue to follow up with your plastic surgeon. (Tom J. Pousti, MD, FACS, San Diego Plastic Surgeon)
After having an undesirable outcome following an elective procedure the first time, I understand your concern for having repeat skin loss/necrosis. From the best I can tell from online photos and without physical exam, it looks as if you are healing normally for this stage. Sometimes, more frequent follow up with your plastic surgeon is a good way to relieve some of the anxiety. Speak with your plastic surgeon about this as I believe it would help you in the postoperative period. (W. Bryant Walker, MD, Jackson Plastic Surgeon)
Though an examination is needed, you do not appear to have necrosis and are healing nicely (Frederic H. Corbin, MD)
You are healing well, there are not signs of skin necrosis, the redness and inflammation are normal for 5 days after the surgery.
