The donor site heals by re-epithelialisation from the dermis and surrounding skin and requires dressings. Full-thickness A full-thickness skin graft consists of the epidermis and the entire thickness of the dermis. The donor site is either sutured closed directly or covered by a split-thickness skin graft. Composite graft
The forehead flap is known as the best donor site for repairing nasal defects because of its size, superior vascularity, skin color, texture and thickness. [1] [3] [4] Especially the color and texture of the forehead skin matches exactly with the skin of the nose. This is why the forehead flap is used so much for nasal reconstruction.
After removal of the cancer, closure of the skin for patients with a decreased amount of skin laxity involves a split-thickness skin graft. A donor site is chosen and enough skin is removed so that the donor site can heal on its own. Only the epidermis and a partial amount of dermis is taken from the donor site which allows the donor site to heal.
Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants. White blood cells of the donor's immune system which remain within the donated tissue (the graft) recognize the recipient (the host) as foreign (non-self).
Free flap. The terms free flap, free autologous tissue transfer and microvascular free tissue transfer are synonymous terms used to describe the "transplantation" of tissue from one site of the body to another, in order to reconstruct an existing defect. "Free" implies that the tissue is completely detached from its blood supply at the original ...

A face transplant is a medical procedure to replace all or part of a person's face using tissue from a donor. Part of a field called "Vascularized Composite Tissue Allotransplantation" (VCA) it involves the transplantation of facial skin, the nasal structure, the nose, the lips, the muscles of facial movement used for expression, the nerves that provide sensation, and, potentially, the bones ...
86.7. [edit on Wikidata] Flap surgery is a technique in plastic and reconstructive surgery where tissue with an intact blood supply is lifted from a donor site and moved to a recipient site. Flaps are distinct from grafts, which do not have an intact blood supply and relies on the growth of new blood vessels.
