This study introduces a novel free paraumbilical perforator flap for reconstruction. This muscle-sparing flap offers advantages over traditional methods, potentially reducing complications like abdominal herniation.

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Microsurgery

Background:

  • Conventional rectus abdominis musculocutaneous flaps present challenges in reconstructive surgery.
  • Alternative flap techniques are sought to minimize donor-site morbidity and improve outcomes.

Observation:

  • A free paraumbilical perforator-based flap, without muscle, was utilized in 13 patients.
  • Seven patients received a thin variant of this flap, incorporating a protective fat layer.
  • The flap's dominant perforator is typically periumbilical, allowing for large flap harvest.

Findings:

  • The paraumbilical perforator flap features a long vascular pedicle and a large skin territory.
  • Advantages include minimal bulkiness and a low incidence of postoperative abdominal herniation.

  • Disadvantages involve technical dissection challenges and potential perforator anatomical variations.

    • Implications:

    • This flap offers a promising alternative to conventional flaps, potentially overcoming their limitations.
    • It may reduce complications such as abdominal herniation and donor-site morbidity.
    • Further research into optimizing perforator dissection and understanding anatomical variations is warranted.
