Skin Grafting

Skin grafting is used whenever a wound is too large, too deep, or too damaged to close on its own or with simple stitches. Surgeons turn to it when the body cannot generate enough new skin to fill a wound by itself.

• Severe burns that destroy the outer and deeper layers of skin
• Large wounds left after removing skin cancer or other skin tumours
• Chronic wounds that have not healed despite weeks of treatment, such as diabetic foot ulcers or pressure ulcers (bedsores)
• Deep injuries from trauma, such as road accidents or industrial accidents, where large areas of skin are torn away
• Wound reconstruction after infection that has destroyed the surrounding tissue, such as necrotising fasciitis (flesh-eating infection)

Skin grafting is a well-established surgical procedure, but like all surgery it carries recognised risks that your surgical team will discuss with you beforehand.

• Graft failure, where the transplanted skin does not attach properly and dies, requiring a repeat procedure
• Infection at the graft site or the donor site
• Pain, swelling, and bruising at both the graft and donor sites during healing
• Scarring or changes in skin colour at the graft or donor site, which may be permanent
• Skin contracture (tightening of the grafted skin over time), especially near joints, which can limit movement

Before surgery, the team will usually ask you to stop eating and drinking for at least six hours, as the stomach must be empty if general anaesthesia (being fully asleep) is planned. If local or regional anaesthesia is used instead, the fasting rules may be different, and the anaesthetist will advise you specifically.

Certain medications are typically paused before the procedure. Blood thinners such as warfarin or aspirin are usually stopped several days in advance because they increase bleeding risk. Anti-inflammatory tablets are often paused for a similar reason. Smoking is strongly linked to poor wound healing and graft failure, so surgeons usually ask patients to stop smoking several weeks before the procedure. Alcohol is usually avoided in the days leading up to surgery, as it can interact with anaesthetic drugs and slow recovery.

Standard pre-operative tests help the team understand your overall health before they operate. These commonly include blood tests to check for anaemia (low red blood cell count), infection, clotting ability, and kidney or liver function, along with a chest X-ray and an EKG (electrocardiogram, a test of heart rhythm) if the patient is older or has existing health conditions. Blood sugar control is checked carefully in diabetic patients, as high blood sugar slows healing.

On the day of surgery, the typical sequence of steps is as follows.

• You are admitted to the hospital and prepared by the nursing team, which includes changing into a surgical gown and having an intravenous (IV) line placed in your arm.
• The anaesthetist reviews your health and administers anaesthesia, which may be general anaesthesia, regional anaesthesia (numbing a large area), or local anaesthesia, depending on the size and location of the graft.

After surgery, patients are monitored in the recovery ward and, in most cases, kept in hospital for at least several days so the graft can be checked regularly. The grafted area must be kept still and undisturbed in the early days, as any movement or shearing force can dislodge the graft before it has attached to the blood supply beneath.

• The first dressing change usually happens between three and five days after surgery, when the surgeon checks whether the graft is taking; the exact timing depends on the wound type and the hospital's protocol.
• The grafted limb or body part is often immobilised with a splint or bandage to prevent movement, especially if the graft is near a joint.
• The donor site heals on its own, much like a superficial burn; it is covered with a non-stick dressing that is left in place for about two weeks in most cases.
• Antibiotics are usually prescribed for a period after surgery to reduce the risk of infection at both sites.
• Pain is managed with prescribed painkillers; the donor site is often more painful than the graft site in the first week.

The cost of skin grafting varies widely from patient to patient and from one hospital to another, because the procedure is tailored entirely to the individual wound. A small graft on a straightforward wound in a public hospital is a fundamentally different undertaking from a complex multi-site graft for severe burns in a private centre, and the pricing reflects that difference.

• Size and depth of the wound: a larger or deeper wound requires more harvested skin, longer operating time, and more surgical staff.
• Type of graft: a split-thickness graft (taking only part of the skin's depth) is less complex than a full-thickness graft (taking the complete skin layer), which affects both surgical time and cost.
• Whether meshing is needed: meshing the graft to cover a wider area adds a step and specialised equipment to the procedure.
• Number of graft sites: some patients need grafts in more than one area, which increases operating time and resources.
• Hospital class and country: private hospitals, international hospitals, and hospitals in higher-income countries charge substantially more than government hospitals or facilities in lower-cost settings.
