In my previous blog post about postoperative Tummy tuck swelling I talked about how the blood supply is disrupted to different degrees using the two different types of Tummy tuck techniques (standard vs. Lockwood). In summary, the more skin that is elevated and separated from the muscle layer, the more blood supply disruption you have. On this post we will address swelling of the tissues after Tummy tuck and why compression garments following surgery are important to reduce swelling. The body is made mostly of water, and there is a constant fluid leakage from the tissues balanced by reuptake of fluid into the lymphatic drainage system. When the lymphatic system is impaired, we get fluid accumulations. The fluid can accumulate between the tissues as interstitial fluid (like a soaked sponge), or outside of the tissues as a seroma (like a sac of fluid). It can also accumulate at some distance from the operative site, usually the upper thighs or legs. The drawing illustrates the various types of fluid accumulation following surgery. As you move from left to right on the illustration you have increasing swelling to result in these conditions:
