Abdominal Wall Reconstruction: Core Principles

Abdominal wall reconstruction is where plastic surgery principles get tested in real time — and it's where most failures start with one wrong assumption about force distribution. In this episode of Plastics in Practice, we review the basics of abdominal wall reconstruction: how to think about the abdomen as a pressurized cylinder, why supported repairs beat bridged repairs almost every time, how to read the components separation technique like a physiology problem instead of a memorization problem, and how to choose between synthetic and bioprosthetic mesh in a contaminated field. We close with soft tissue strategy — when to skin graft early, when to reach for a perforator flap, and how to decide between rebuilding the wall first or rebuilding the cover first. Key takeaways: Hernias expand because sutures cut through tissue like a wire through ice — load-sharing supported repairs are the answer, not bigger primary sutures. Large hernias convert isometric abdominal contraction into isotonic shortening, derailing diaphragm function and torso mechanics — repair restores physiology, not just anatomy. Components separation can move each rectus 8–10 cm to the midline through external oblique release alone; preserving periumbilical perforators is what keeps the skin alive. Synthetic mesh is for clean fields. Bioprosthetic mesh is for contamination, radiation, bowel suture lines, or any field where the soft tissue cover might fail. In the open abdomen, early skin grafting over granulated bowel is your friend — it heals in two dimensions and tolerates poor nutrition far better than flaps. If the hernia is expanding, it's ready to repair — that means the adhesions have softened enough to dissect cleanly.
