The source (donor site) most commonly used for skin grafts include the lateral thigh, buttocks, below the collarbone, in front of and behind the ear, and the upper arm.
How much of my skin will be needed for skin graft?
The amount of skin needed for a graft depends on skin thickness and where and why the graft is needed. There are two different types of skin grafts, Full-thickness skin graft and Split-thickness skin graft.
- Full-thickness skin graft: This is also called FTSG. Full-thickness skin grafts are made up of epidermis and the whole thickness of the dermis. If FTSG is to be used, a piece of your skin will be cut into the correct size and shape to fit the wound.
- Split-thickness skin graft: This is also called STSG. Split-thickness skin grafts have the epidermis and part of the dermis. This type of skin graft is taken by shaving the layers of the skin using a large knife.
