How long does it take for a skin graft to fully heal?
The donor area of partial thickness skin grafts usually takes about 2 weeks to heal. For full thickness skin grafts, the donor area only takes about 5 to 10 days to heal, because it’s normally quite small and closed with stitches.
What causes a skin graft to fail?
The most common cause of graft failure is movement, which dissociates any new blood vessel growth (neovascularization) into the graft, depriving it of oxygen and nutrients. This complication causes fluid collection between the graft and the graft site bed (hematoma or seroma), further separating the graft from the bed.
What are the complications of skin graft?
What Are the Risks of a Skin Graft?
- Bleeding.
- Graft failure.
- Infection at either the donor or recipient site.
- Poor healing.
- Increased or decreased sensation at the recipient site.
- Hair may not grow on recipient site.
- Graft tissue contracts, interfering with limb movement.
- Scarring.

Where is cadaver skin from?
Cadaver skin is removed from donors shortly after their deaths, then processed and distributed by skin and tissue banks. It has long been the preferred option for a patient with the most severe burns until a graft of the patient’s own skin can be applied.
Is a skin graft major surgery?
Skin grafting involves removing damaged or dead skin tissue and replacing it with new, healthy skin. Skin grafting is major surgery with serious risks and potential complications.

What is the importance of dissection?
