Le Reviva Reviews : There are two types of skin grafts: autografts and allografts. In all skin graft procedures, skin must be removed from site A then attached to the wounded area or site B. Le Reviva The most preferred source of skin for any skin grafting procedures is from the patient himself, this is called an autograft. The body's immune system will ultimately try and reject foreign skin which is why sourcing from the patient himself is the best option for long-term treatment.
A similar graft, Xenografts, are temporary skin covering from animals (usually pigs) that can only last three to five days before they are rejected. Allografts and xenografts are primarily used to buy time for the patient. In most cases, they can provide enough protection to allow the skin to regenerate on its own. When autografts are necessary, there are three major types to choose from. Deciding on which autograft method to use is dependent on the amount and depth of the skin loss on the patient.
A Split-thickness graft is used for the shallowest wounds, those that affect only the epidermis and part of the dermis. It is called a split-thickness graft because the doctor removes only a few layers of skin from the donor site. Similar to split-thickness grafts, full-thickness grafts require all three skin layers, the epidermis, dermis and hypodermis, to be removed from the donor site.
