What is split-thickness skin grafting?
During a split-thickness skin graft, your surgeon will remove a thin layer of skin from 1 part of your body (donor site) and use it to close the surgical site that needs to be covered (recipient site). You may have a split-thickness skin graft if you lost a large area of skin due to an infection, burn, or surgery.
Which body site is not ideal for a split-thickness skin graft?
This may be the base of a finger but is more often a superficial avulsion on the dorsum or sometimes the palmar surface of the hand. Split-thickness grafts will not suffice for deeper avulsions, which have left tendons, nerves or vessels, or bony repairs with hardware exposed.
Why is a full-thickness skin graft better than a split-thickness skin graft?
The split-thickness technique is used to cover large areas, which makes it ideal for the legs. Full-thickness skin grafts are usually reserved for smaller areas, such as the face and hands, because they blend better with the surrounding skin.
What is the difference between split-thickness and full-thickness skin graft?
Split-thickness skin grafts (STSG) are composed of the epidermis and a superficial part of the dermis. Full-thickness skin grafts (FTSG) contain both the full epidermis and dermis. Composite grafts contain skin and another type of tissue, usually cartilage.
What are the three types of skin grafts?
Depending on the origin: Autograft or autologous graft: skin obtained from the patient’s own donor site. Allograft or heterologous graft: skin obtained from another person. Xenograft or heterograft: skin from other species, such as pigs.
How thick is a split-thickness skin graft?
If less than the entire thickness of the dermis is included, this graft is referred to as a split-thickness skin graft (STSG). STSGs are categorized further as thin (0.005-0.012 in), intermediate (0.012-0.018 in), or thick (0.018-0.030 in), based on the thickness of the harvested graft.
What are the 4 types of skin grafts?
Depending on the origin:
- Autograft or autologous graft: skin obtained from the patient’s own donor site.
- Allograft or heterologous graft: skin obtained from another person.
- Xenograft or heterograft: skin from other species, such as pigs.
- Synthetic skin substitutes: manufactured products that work as skin equivalents.
What are the 4 types of grafts?
There are four classifications of grafts: (1) autograft (tissue removed from one site and surgically implanted into another on the same individual); (2) isograft (tissue removed from an individual and surgically grafted onto a genetically identical individual, such as an identical twin or another member of the same …
What is a flap skin graft?
A “skin graft” is the transfer of a portion of the skin (without its blood supply) to a wound. A “flap” consists of one or more tissue components including skin, deeper tissues, muscle and bone.
What is a flap graft?
Flap surgery involves a piece of tissue that still receives blood supply because it’s attached to the body by a major artery and vein or at its base. This piece of donor tissue is used in reconstructive surgery by being set into the recipient site (injured area onto which a flap or graft is placed).
Is a flap a skin graft?
What is the difference between flaps and split-thickness skin grafts?
Unlike flaps, skin grafts do not have their own blood supply, so they must rely on a well-vascularized wound bed for graft in-growth. Split-thickness skin grafts are obtainable from multiple sources (autograft, homograft, allograft, or xenograft), multiple anatomical locations, and in various thicknesses.
What is the technique for harvesting a split-thickness skin graft with dermatome?
The technique for harvesting a split-thickness skin graft with an air-powered dermatome will be described as it is a common harvesting method. Preparation of Wound Bed and Split-thickness Skin Graft Harvest
What are split split thickness skin grafts (SSG)?
Split thickness skin grafts (SSG’s) consist of the epidermis and a partial thickness of the dermis. Joyce C. Chen MD, Sonu A. Jain MD, in Plastic Surgery Secrets Plus (Second Edition), 2010 14 What are the choices for donor sites? STSG can be taken from any area of the body.
What is the success rate of split-thickness skin grafts?
Skin graft take: Split-thickness skin graft take is consistently reported at around 70 to 90%, even when accounting for a variety of recipient wound beds. [15][16][17][18]TBSA burned over 35%, age greater than 55 years old, and the presence of diabetes mellitus can adversely affect the success rate of STSGs.
