Description of Procedure
The wound will be measured. A pattern of the wound will be traced and then outlined over the donor site. The donor tissue will be removed with a scalpel or special harvesting machine.
There are three main types of skin graft techniques:
- Split-thickness graft—This is the removal of the top layer of skin and part of the middle layer. This type of graft allows the source site to heal more quickly. The graft is more fragile. It may also be abnormally pigmented (color differences). This type of graft may be meshed. This is a technique which places multiple controlled holes in the graft. It will give it a mesh appearance. The mesh allows fluid to leak out from the underlying tissue bed. The meshed skin will be able to spread out over a much larger area of injury.
- Full-thickness graft—This is the removal and transfer of an entire area of skin. Although this type of graft requires stitches to heal the source site, the final outcome is usually better. Full-thickness grafts are usually recommended for areas where cosmetic appearance is important, such as the face. Full-thickness grafts can only be placed on areas of the body that have significant vascularization (blood vessels). Its use is somewhat limited.
- Composite grafts—This is a combination of skin and fat, skin and cartilage, or the middle layer of skin and fat. It is used in areas that require three-dimensionality, such as the nose.
The graft will be placed on the damaged site. It will be fastened with stitches or staples.
A pressure bandage will be applied over the area. A wound VAC may be placed for the first 3-5 days. This is a device that has suction and is used to control drainage. Initially, the graft will survive on oxygen and nutrients from the underlying tissue. Within 36 hours, new blood vessels begin to grow. New cells will grow from the graft to cover the damaged area with new skin.

Average Hospital Stay
This varies depending on the reason for the graft, the size of the graft, as well as other care that is needed. For example, recovery from a burn or accident may take longer.
