Rectus Sheath Flap Applications in Modern Plastic Surgery: From Abdominal Wall to Breast Reconstruction

The anterior rectus sheath is one of the most underutilised yet powerful tissues in plastic surgery. Strong, thin, well-vascularised when raised in continuity with intercostal perforators, and harvestable with negligible donor-site morbidity, it deserves a much wider role in modern reconstruction. Prof. Dr. Karaaltın uses rectus sheath strips as a core component of his composite ICAP flap for breast deformity correction.

Why Rectus Sheath Is So Useful

• High tensile strength — holds permanent sutures reliably
• Thin and pliable — easily inset without bulk
• Excellent integration with surrounding tissues
• Can be raised as a vascularised strip with intercostal perforators
• Donor site closes primarily without functional loss

Key Applications

1. Breast Reconstruction Support

As part of a composite ICAP flap, a rectus sheath strip recreates the inframammary fold, supports the implant, and acts as an autologous internal bra.

2. Abdominal Wall Reconstruction

Rectus sheath turnover flaps reinforce midline defects and complement mesh repair in complex hernias.

3. Pelvic and Perineal Reconstruction

Pedicled rectus sheath–containing flaps assist in reconstructing complex pelvic defects.

4. Tendon and Soft-Tissue Reinforcement

Rectus sheath grafts can reinforce tendon repairs and soft-tissue defects when biological strength is required.

Donor-Site Considerations

Closure must be meticulous, with non-absorbable sutures and, if needed, mesh reinforcement to prevent bulge or hernia. When harvested as a narrow strip, the donor site heals predictably.

The Future

As reconstructive surgery moves toward autologous biological scaffolds over synthetic mesh, the rectus sheath — particularly in composite vascularised flap form — is set to play a central role. Dr. Karaaltın''s composite ICAP work is one example of where this future is already practiced today.
