Why do you think you have fat necrosis in your upper abdominal area? The most commona area for fat necrosis following a standard type tummy tuck is in the midline near the horizontal incision at your waist. This usually presents with redness, wound healing problems, and drainage. Fat necrosis in the upper abdominal area is very rare. If you feel like you have excess fullness in this area this may be the result of:
-insufficient abdominal wall plication
The first can be treated with liposucton. The second and third will require a revision tummy tuck.
All the best,
