Necrotising fasciitis (NF) is a potentially life threatening condition that can cause significant damage to skin and tissue. In severe cases, surgical removal of the infected tissue (debridement) is necessary. This often leaves large wounds that require skin grafts to aid in healing and recovery.
What is a Skin Graft?
A skin graft is a surgical procedure where healthy skin is taken from one part of the body (the donor site) and transplanted to cover the wound (the recipient site). To avoid confusion here, most skin grafts, called autografts, use skin from the same person, not a third party.
Types of skin graft
As we already mentioned, most skin grafts are from another site on the same person’s body (autografts). It is also possible to obtain a skin graft from a third party, this is know as an allograft.
There are two main types of skin grafts:
- Split-thickness grafts: These grafts include the epidermis (the outer layer of skin) and part of the dermis (the deeper layer).
- Full-thickness grafts: These grafts include the entire epidermis and dermis.
The type of graft used depends on factors such as the depth and size of the wound, the location on the body, and the patient’s overall health.
Why are they the treatment of in Necrotising Fasciitis?
Skin grafts play a crucial role in the treatment of NF by:
- Promoting wound healing: Skin grafts help to cover and protect the wound, creating a barrier against infection and promoting the growth of new tissue.
- Reducing scarring: Skin grafts can help to minimize scarring and improve the cosmetic outcome of the wound.
- Improving function: In cases where NF has affected muscles or tendons, skin grafts can help to restore function and mobility.
What if a Skin Graft Fails?
While a skin graft is often successful, there’s a chance it might fail. This can happen for various reasons, such as infection, poor blood supply, or movement that disrupts the graft. We’ll be adding another blog post soon to look at skin graft failure in more details.

Conclusion
Skin grafts are a vital tool in the treatment of necrotising fasciitis. They promote wound healing, reduce scarring, and improve function. While graft failure is a possibility, medical advancements and vigilant care have significantly improved the success rates of skin grafts.
