Skin grafting involves using a section of normal skin from one part of the body (the donor site) to cover another site where the skin has been lost as a result of an injury, such as a burn, or a disorder, such as an ulcer. There are several different methods of skin grafting. The two examples shown here use small donor sites to cover large areas of missing skin.
A meshed graft is used when a very large area of missing skin needs to be covered and donor sites are limited. The donor skin is removed and made into a mesh using angled cuts. The meshed graft can then be stretched to cover the large area of missing skin.
Pinch grafts are very small pieces of skin that are often used to help skin ulcers to heal. Multiple small grafts are pinched up and removed from the donor site. The pinch grafts are then placed over the larger area of missing skin and grow to cover the area.
