Skin Grafts for Reconstructive Surgery

Learn about the types and techniques of skin grafts used in reconstructive surgery, including split thickness and full thickness grafts. Discover the importance of proper donor site selection and recipient site preparation, and understand the care required for both the graft and donor site. Explore the potential complications and pearls for successful outcomes.

  1. Skin grafts For Reconstructive surgery Presented by: 10301010094 陈玩娜 10301010095 黄晓铨

  2. Introduction • Trauma, infection, or surgery • Sutures or staples for wound closure • Skin graft for full thickness abrasions

  3. Skin Grafts • A skin graft is the transfer of skin from a donor site to a recipient site. • Lacking blood supply • Surviving by plasmatic imbibition • Neovascularization: over 48 to 72 hours • Full circulation: within 4 to 7 days

  4. Types of skin grafts • Split thickness skin grafts (STSG) • Full thickness skin grafts (FTSG) The whole epidermis layer A portion of skin Some of the underlying dermis The entire layer of skin

  5. How to choice?

  6. Surgical technique • Donor site selection • Desired color, texture and thickness • Inconspicuous areas • Recipientsite preparation • Well vascularized • Free of all necrotic or ischemic tissue • No accumulation of blood or fluid

  7. How is a skin graft done? • Harvest • Graft meshing • Graft inset • Recipient site care • Donor site care

  8. Harvest • Harvested from healthy donor site with dermatome • Tension skin with mineral oil

  9. Graft meshing • Perforated using a skin graft mesher. • Improvement of coverage, drainage and healing of skin

  10. Graft inset Dermis-side-down

  11. Recipient site care Negative pressure wound therapy: The foam insert (sponge) is covered by a clear, vapor permeable, plastic dressing. Continuous subatmospheric pressure causes fluid to flow out of the wound.

  12. Donor site care

  13. Graft maturation • 3 to 6 months to mature. Erythematous and irregular Smooth but inconsistent in color

  14. Graft failure • Graft movement • Comorbidities: diabetes, smoking, protein or vitamin deficiencies. • Infection: Methicillin-resistant coagulase-positive staphylococci (MRSA), β-hemolytic streptococcus, or pseudomonas

  15. Pearls • The routine use of grafts improve outcomes and quality of life for trauma patients, burn patients, and cancer patients • A skin graft is a transfer of skin from the donor site to the recipient site without the benefit of any blood supply. • STSG transfer a portion of the donor site skin layer including the epidermis and some of the underlying dermis. • FTSG harvest the entire layer of skin as the graft. • Proper preparation of the recipient site is crucial.
