Skin necrosis following abdominoplasty refers to the death of skin tissue due to inadequate blood supply. While it affects only a small percentage of tummy tuck patients, it is important to understand the risk factors, warning signs, and treatment options so you can respond quickly if it occurs.
What Causes Skin Necrosis After Tummy Tuck?
During a tummy tuck, the surgeon elevates and repositions a large flap of abdominal skin. This temporarily disrupts blood flow to parts of the flap. In most cases, blood supply re-establishes itself during healing. Necrosis occurs when blood flow is insufficient or is further compromised by contributing factors:
- Smoking: The single greatest modifiable risk factor, nicotine severely constricts blood vessels
- Diabetes: Impairs circulation and slows wound healing
- Obesity or high BMI: Increases tension on the flap and reduces perfusion
- Excessive undermining: Surgical technique that disrupts too much perforating blood supply
- Seroma or hematoma: Fluid collections that compress tissue and restrict blood flow
- Tight closure: Excessive tension across the incision line limits blood supply to the skin edge
Warning Signs to Watch For
Necrosis most commonly affects the area around the incision line or the umbilicus (navel). Contact your surgeon immediately if you notice:
- Skin that is turning dark purple, blue, or black
- A clearly demarcated area of skin that looks different from surrounding tissue
- Skin that feels hard, leathery, or insensate
- Foul-smelling discharge or wound breakdown at the incision
- Fever accompanying any of the above signs
How Is Necrosis Treated?
Treatment depends on the extent of affected tissue. Small areas of superficial necrosis may be managed conservatively with wound care, enzymatic debridement, and dressing changes. Larger or deeper areas may require:
- Surgical debridement (removal of dead tissue)
- Hyperbaric oxygen therapy to promote healing in some cases
- Scar revision surgery after the wound has fully healed
The best protection against tummy tuck necrosis is choosing a board-certified surgeon with extensive abdominoplasty experience, being honest about your health history, quitting smoking at least 6 weeks before surgery, and following all pre- and post-operative instructions carefully.
