A split thickness skin graft takes the upper layers of skin from a donor area and lays them over a raw wound. It covers large areas quickly, and the donor site heals by growing new surface skin from within.
A split thickness skin graft is a thin sheet of skin, shaved off with a blade set to take the surface layer and part of the dermis beneath. It is laid on a clean wound and held still until it picks up a blood supply. Because the donor area keeps its deeper structures, it heals over by itself without stitches.
Skin has two working layers. The thin outer layer gives the waterproof surface, while the thicker dermis below carries strength, sweat glands and hair roots. A split thickness graft takes the outer layer plus only part of the dermis, so the deeper structures stay behind in the donor area. Those leftover structures are what allow the donor site to resurface itself over a couple of weeks.
Because the graft is thin, it survives on wound beds that thicker skin would reject. Nutrients soak in from the wound at first, and new blood vessels grow in over the following days. That is why stillness matters so much in the first week, and why bleeding or fluid under the graft is such a common reason for failure.
Thinness has a price. Split thickness skin contracts more as it settles, so it is a poor choice beside an eyelid, a lip or across a joint unless splinting is planned. It also heals with its own colour and shine, which may not match nearby skin. For cover of a large area, though, nothing else is as quick or as dependable.
A split thickness graft suits large wounds that need cover quickly and have a clean, well supplied base. It is chosen for reliability of take rather than for appearance.
First the wound is cleaned and every trace of dead tissue removed, so the graft sits on healthy tissue that bleeds. A bed covered in slough or heavily infected will not hold a graft.
A powered or hand held blade then shaves a thin sheet from a donor area, commonly the outer thigh. Depth is set on the instrument, so deeper skin structures stay behind to heal the site.
The sheet may be passed through a machine that cuts small slits across it. Meshing lets the graft stretch over a wider area and lets fluid drain through instead of gathering underneath.
Next the graft is laid on the wound and held with fine sutures, staples or glue. A firm dressing, sometimes a negative pressure dressing, keeps it pressed against the bed while it takes.
Lastly the donor area is covered with a dressing left in place while new surface skin grows across it from the structures that remain in the deeper layer.
Dressings are usually left undisturbed so the graft is not shifted. A grafted limb is kept raised and rested, because movement is the main enemy of graft take.
The first dressing check shows how much of the graft has taken. The donor site is often the sorer of the two and may weep for a while.
Most grafts are stable by now and the donor site has usually resurfaced. Moisturiser and gentle massage begin once both surfaces are intact, and compression may be advised.
Colour and texture settle slowly. Contraction is strongest in the early months, so splints and therapy may continue where a joint is involved.
A graft that takes gives durable cover, yet it rarely matches the skin around it. Split thickness skin often heals paler, darker or shinier than its surroundings, and the edge may stay visible. Contraction carries on for months, which matters most near a joint or a free edge. The donor site usually heals as a flat patch of altered colour that fades slowly. Some grafts take only in part and need a further procedure.
Grafting is a dependable technique, though take is never certain and the operation creates two wounds instead of one.
Two areas need attention after this operation. The graft needs stillness while it takes, and the donor site needs protection while it resurfaces.
Grafted skin survives and gives cover, but it usually differs in colour, texture and sweating from the skin around it.
Many patients report the opposite. The donor area is a fresh raw surface with intact nerve endings, and it is often the sorer of the two.
Thin grafts take more reliably on a difficult bed. Thicker skin looks better but demands a healthier bed and a donor site that has to be stitched.
Grafted skin contracts and dries for months, so moisturiser, sun protection and sometimes splinting continue well after the operation.
At Elegance Clinic in Surat, grafting starts with wound bed preparation, because a graft only performs as well as the surface it is laid on.
Technique pages do not carry their own price, because the cost depends on the treatment the technique is used within. Grafting a small ulcer and grafting a large burn are very different operations in theatre time and dressings.
Before admission you receive a written estimate covering surgery, anaesthesia, dressings for both sites and planned review visits. For bands, please see the relevant treatment page or the costs section.
These are the questions that come up most often in consultation. If yours is not here, send it on WhatsApp and the team will reply, usually the same day.

It is a standard reconstructive procedure with a well understood risk profile. The main concerns are graft loss, bleeding under the graft and infection at either site. Anaesthetic risks are assessed beforehand and discussed at the pre admission visit.
Often the donor area rather than the grafted wound. Shaving skin leaves a raw surface with intact nerve endings, and it can sting for several days. Pain relief is planned around dressing changes, and discomfort settles as the surface heals.
New blood vessels grow in over roughly the first week, which is why the dressing is left undisturbed and the area kept still. Full settling of colour and texture takes many months, and recovery can vary between people.
Usually not exactly. Split thickness skin tends to heal paler, darker or shinier than the area around it, and a net pattern remains where the graft was meshed. Colour keeps changing for months before it settles.
Anyone whose wound exposes bare bone, tendon or cartilage, since a graft needs blood supply from the base. Wounds on the face, across joints or beside a free edge are often better served by a thicker graft or a flap.
The wound is assessed for depth and cleanliness, donor site options are discussed, and photographs may be taken. Smoking, diabetes control, circulation and medicines are reviewed because they all affect graft take, and a written estimate follows.
