Full-thickness: Involves excising a defined area of skin, with a depth of excision down to the fat. The full thickness portion of skin is then placed at the recipient site. A full-thickness skin graft is more risky, in terms of the body accepting the skin, yet it leaves only a scar line on the donor section, similar to a Cesarean-section scar.
An escharotomy is a surgical procedure used to treat full-thickness (third-degree) circumferential burns. In full-thickness burns, both the epidermis and the dermis are destroyed along with sensory nerves in the dermis. The tough leathery tissue remaining after a full-thickness burn has been termed eschar. Following a full-thickness burn, as ...
Skin grafting can reduce the course of treatment and hospitalization needed, and can also improve function and appearance. There are two types of skin grafts: Split-thickness skin grafts (the epidermis and part of the dermis) Full-thickness skin grafts (the epidermis and the entire thickness of the dermis)
For skin grafts, the newly grafted skin is fragile to damage. Slight bleeding may occur, which can be managed by removing serosanguineous material or necrotic debris using hydrogen peroxide. If eschar is present which affects the grafted skin, debridement should only be done when the area of necrosis is clearly defined. [31]
As the deep shave excision either completely removes the full thickness of the dermis or greatly diminishes the dermal thickness, subcutaneous fat can herniate outward or pucker the skin out in an unattractive way. In areas prone to friction, this can result in pain, itching, or hypertrophic scarring. [citation needed]
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.
In 2008, in full thickness wounds over 3mm, it was found that a wound needed a material [clarify] inserted in order to induce full tissue regeneration. [9] [10] Whereas 3rd degree burns heal slowly by scarring, in 2016 it was known that full thickness fractional photothermolysis holes heal without scarring. [1]
Autologous full-thickness grafts involving transplantation of the entire epidermis and dermis to provide better cosmetic outcomes can be used for smaller wounds. [19] As for larger wounds, autologous split-thickness grafts involving transplantation of the epidermis and partial portion of the dermis are used. [ 19 ]
