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. In the case of full-thickness skin grafts, the donor section will often heal much more quickly than the injury and causes less pain than a partial-thickness skin graft.
In full thickness wounds, contraction peaks at 5 to 15 days post wounding. [37] Contraction can last for several weeks [46] and continues even after the wound is completely reepithelialized. [3] A large wound can become 40 to 80% smaller after contraction.
In the United States, pressure ulcers are graded using the National Pressure Injury Advisory Panel (NPIAP) system. In this system, ulcers are graded on wound depth with stage 1 being the least severe (erythema, intact skin) and stage 4 being full thickness damage through subcutaneous tissue down to muscle, tendon, or bone.
Skin graft with vacuum-assisted wound closure after 5 days. STSGs are suitable for large wounds and relatively avascular sites where FTSGs would have a high risk of failure. Only a portion of the skin, namely the epidermis and part of the dermis, is removed from the donor site using a powered dermatome. [17]
Unstageable: Full thickness tissue loss in which actual depth of the ulcer is completely obscured by slough (yellow, tan, gray, green or brown) and/or eschar (tan, brown or black) in the wound bed. Until enough slough and/or eschar is removed to expose the base of the wound, the true depth, and therefore stage, cannot be determined.
Venous ulcer is defined by the American Venous Forum as "a full-thickness defect of skin, most frequently in the ankle region, that fails to heal spontaneously and is sustained by chronic venous disease, based on venous duplex ultrasound testing."
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 ...
These wounds pose only a small risk of contracture and hypertrophic scarring. Full-thickness (FT) injuries cause dermal wound healing, which is characterized by maturation (contraction and increased tensile strength), proliferation (collagen synthesis leading to wound closure), and inflammation . FT wounds heal by excision and grafting ...
