Staged wound reconstruction

Dermal Substitutes

Dermal substitutes are engineered scaffolds placed on a wound so the body can build a new dermal layer. Once that layer has formed, a thin skin graft is applied over it, usually as a second stage some weeks later.

Quick answer

A dermal substitute is a scaffold laid on a wound where the deeper skin layer is missing. Over some weeks, blood vessels and the body's own cells grow into it and create a layer that behaves more like dermis than scar. A thin skin graft is then placed on top. This staged plan suits wounds where a graft alone would give poor cover.

Key takeaways
  • A dermal substitute is a scaffold that lets the body rebuild a dermal layer before a thin skin graft is applied over it.
  • It helps where exposed tendon, bone covering or joint capsule leaves a bed too poor for a graft on its own.
  • Treatment is staged, so the scaffold usually stays on the wound for some weeks before the graft is placed.
  • Rebuilding dermis can give softer, more supple cover and less contraction than a thin graft laid straight on the wound.
  • Substitutes add material cost and a second procedure, and they still need a clean wound free of active infection.
Dermal substitute: A dermal substitute is a sheet of engineered scaffold placed on a wound so that new tissue and blood vessels can grow into it before skin grafting.

What dermal substitutes do

When the dermis is lost, a thin skin graft laid straight onto the wound gives cover but little substance. The result can be tight, fragile and stuck down to whatever lies beneath. Dermal substitutes were developed to answer that problem by rebuilding a layer before the surface is replaced.

The scaffold is a sheet of engineered material, usually based on collagen, with a structure that cells and blood vessels can move into. It is secured on a clean wound and left in place. Over the following weeks the body grows its own tissue through the scaffold, so the wound gains a supple layer with a blood supply of its own.

Once that layer is established, a thin skin graft is applied over it at a second operation. Because the new bed is well supplied, a very thin graft is usually enough, which keeps the donor wound shallow. The result is cover that tends to move and stretch more like skin. What it costs is time, an extra procedure and the price of the material, so the technique is reserved for wounds where it genuinely earns its place.

Wounds where a substitute may be considered
✦Deep burns where a thin graft alone would leave tight, fragile cover
✦Wounds exposing tendon or bone covering, where a graft would not take directly
✦Release of tight scars across the neck or a joint
✦Large defects where a flap is not suitable or not available
✦Long standing wounds with a poor bed, under specialist care
✦Areas where supple cover matters, such as the back of the hand

Signs the reconstruction needs review

Fluid collects under the scaffold, or the sheet lifts away from the wound.
The wound smells offensive, or discharge becomes thick and cloudy.
Surrounding skin turns red, hot and increasingly tender.
Fever or feeling generally unwell while the scaffold is in place.

When a staged reconstruction is the right choice

This route suits wounds that need better quality cover than a graft alone can give, in patients able to commit to a plan that runs over weeks.

May be suitable when
✦The wound bed is too poor for a graft, while a flap is not a practical option.
✦Supple cover matters, as it does over a joint or on the hand.
✦The wound is clean, with no active spreading infection.
✦Regular reviews over several weeks are realistic for the patient.
May not be suitable when
✦Infection is active in the wound, since a scaffold placed on infected tissue rarely integrates.
✦The wound is straightforward and would be well closed by a graft or a local flap alone.
✦Blood supply to the area is poor, so nothing will grow into the scaffold.
✦Frequent review is impractical, or the extra cost of a staged plan is not workable for the family.

How the staged reconstruction works

01
Preparing the wound

The wound is cleaned thoroughly and all dead tissue removed. Bleeding is controlled carefully, because a collection under the scaffold prevents tissue from growing into it.

02
Applying the substitute

Next the sheet is cut to shape, laid on the wound and secured with sutures or staples. A dressing, often a negative pressure dressing, holds it in close contact with the base.

03
Waiting for ingrowth

Over the following weeks, blood vessels and cells grow through the scaffold. Reviews check for fluid collections and infection, and dressings are changed to a set schedule.

04
Skin grafting

When the new layer looks pink and well supplied, a thin skin graft is applied over it at a second operation and held with a firm dressing while it takes.

05
Scar and function care

Afterwards, moisturiser, massage, splinting and therapy keep the reconstructed area supple, which matters most across a joint or the neck.

How the reconstruction progresses

Week 1 to 2

The scaffold stays undisturbed under its dressing. Rest and elevation matter, and the area is kept still to protect contact with the wound bed.

Week 3 to 4

Reviews assess how far tissue has grown into the scaffold. A change in the colour of the sheet is one of the signs the team looks for.

Week 5 to 8

Once the bed is ready, the skin graft is applied and then treated like any graft, with stillness and elevation for the first days.

Month 6 and beyond

The reconstructed area softens and settles. Moisturiser, sun protection and therapy continue, and contraction is reviewed at each visit.

What this approach can achieve

✦Cover becomes possible on beds that would not support a graft on their own.
✦The reconstructed area is often more supple than a thin graft placed directly.
✦Contraction across joints and the neck is usually less than with a graft alone.
✦It can avoid a large flap operation in patients who would not tolerate one.
✦Only a very thin graft is needed at the second stage, so the donor wound stays shallow.

What results are realistic

Reconstruction with a substitute takes longer than grafting alone, and the surface is still grafted skin rather than original skin. Colour and texture differ from the surrounding area, although the cover is usually more supple than a thin graft laid straight on the wound. Some sheets fail to integrate and have to be replaced. Outcomes depend on the quality of the wound bed, on infection control and on how well the area is protected while tissue grows in.

Risks of a staged plan

This route carries the risks of both operations, along with the specific problem of a scaffold that does not integrate.

Infection under the scaffold, which usually means removing and replacing it.
Blood or fluid collecting beneath the sheet and preventing tissue from growing in.
Failure of the substitute to take up, so the stage has to be repeated or the plan changed.
Loss of the skin graft at the second stage, needing a further procedure.
Longer overall treatment, with more dressings, visits and cost than a single graft.

Caring for the wound and the donor site

Care spans the wound where the scaffold sits and, later, the donor area used for the graft. Both need protection while the reconstruction matures.

✦Keep the area still and raised as advised, especially during the first weeks.
✦Attend every dressing appointment, because fluid under the sheet must be found early.
✦Do not press, rub or wet the dressing at home.
✦After grafting, moisturise daily and use splints or compression if they are prescribed.
✦Report fever, an offensive smell or rising pain instead of waiting for the next visit.

Common misunderstandings

MythA dermal substitute is artificial skin that replaces the graft.
In practice

It builds a base layer only. A skin graft is still needed on top, because the scaffold provides no surface layer of its own.

MythUsing a substitute makes reconstruction faster.
In practice

Usually the opposite. The scaffold needs weeks to be taken up, so this route trades time for better quality of cover.

MythAny wound can be improved with a scaffold.
In practice

Infected or poorly supplied wounds will not integrate one, and simple wounds are closed better by a graft or a local flap.

MythOnce grafted, the area behaves like normal skin.
In practice

Cover is more supple than a graft alone, yet sweating, hair growth and sensation are still not the same as untouched skin.

Cost & insurance

Cost and insurance

Technique pages do not carry their own price, because the cost depends on the treatment the technique is used within. A staged reconstruction also involves the price of the scaffold material itself, which varies with the size of the wound.

Where this plan is recommended, the written estimate issued before admission sets out both stages, the material, dressings and review visits. For bands, please see the relevant treatment page or the costs section.

Because it involves two operations and an engineered material, both of which add to the total. The page itself carries no price, as cost depends on wound size and the treatment involved. A written estimate covering both stages is given before admission.

These scaffolds are made for this purpose and are used widely in reconstructive surgery. The main concern is infection or fluid collecting underneath, which is why dressings are checked on a schedule rather than left for long periods.

Usually some weeks between the two operations, since tissue has to grow into the scaffold before grafting. The exact interval is judged by how the wound looks at review, so the timeline can vary from person to person.

Discomfort is comparable, though there are two operations rather than one, and dressing changes over a longer period. Pain relief is planned around those changes, and most discomfort settles once the surface has been grafted.

The surface is grafted skin, so it differs in colour and texture from surrounding skin. What usually improves is suppleness, because the rebuilt layer allows the area to move and stretch more naturally than a thin graft alone.

Anyone with active spreading infection or poor circulation in the area, since the scaffold will not integrate. Simple wounds that a graft or local flap would close well do not need it either, and the extra stage is then unjustified.

The wound is examined, the reason for a staged plan is explained, and alternatives including grafts and flaps are compared. Diabetes control, smoking and circulation are reviewed, along with the material cost, before a written estimate is issued.
