Ladder outlines increasing complexity of flap.
- Direct closure
- Autologous Skin Graft
- Split-Skin Graft (SSG): Composed of epidermis and part of dermis, harvested with a power-driven dermatome. Donor sites heal in 2 weeks. Pain and itch at donor site (treated with NSAIDs, Panadol).
- Full-Thickness Skin Graft (FTSG): Composed of epidermis and dermis, used in small areas where thickness, appearance, and texture are important (e.g., post-auricular skin for facial reconstruction).
- Rotation or Pedicle Flaps
- Rotation flaps: Arteriovenous connections intact, flap rotated to cover a neighboring defect. Examples include pectoral muscles for neck and latissimus dorsi for breast reconstruction.
- Free Flaps
- TRAM Flap: Free transverse rectus abdominis myocutaneous flap for breast reconstruction.
- Free Gracilis Muscle Flap: Used for lower limb trauma coverage.
- Free Radial Forearm Fasciocutaneous Flap: Used for oropharyngeal reconstruction after tumor excision.
Flaps can fail in 1% to 5% of cases, with the highest risk occurring in the first 2 days following operation
Implications for survival :
- Local flaps eg Rotation : rely on surrounding blood supply, vascular compromise can occur due to tension
- Pedicles flaps : maintain there own vascular supply but survival depends on preserving the pedicle and its blood flow during transfer. Trauma to the pedicle compromises
