Local flap technique

Advancement Flap

An advancement flap moves skin straight forward into the defect beside it, without turning or pivoting. Incisions are placed so the flap slides into position and the resulting scars follow natural lines of the face or body wherever that is possible.

Quick answer

An advancement flap is a piece of skin released on its sides and slid straight into the neighbouring defect. It stays attached at its base, which keeps the blood supply running into it. Because the tissue moves in one direction only, the scars can usually be tucked into a wrinkle line, a hairline or the border between two areas of the face.

Key takeaways
  • An advancement flap slides skin forward into the wound beside it, staying attached at its base for blood supply.
  • Since the tissue moves in one direction, the scars can usually be hidden in a natural line or facial border.
  • It suits areas with skin to spare next to the defect, such as the forehead, cheek and lip.
  • Small triangles of skin are often removed at the base so the flap lies flat instead of bunching up.
  • Where the skin nearby is tight or fixed, advancement pulls on the wound and another flap design is safer.
Advancement flap: An advancement flap is a section of skin, released along its sides but left attached at its base, that slides straight forward to close a nearby defect.

What an advancement flap does

Skin is elastic, and there is often more of it beside a wound than the wound itself needs. An advancement flap uses that surplus. Two parallel cuts are made from the edges of the defect, the skin between them is lifted from the tissue below, and the whole block is slid forward until it meets the far edge. Nothing is rotated or lifted over a bridge, which is what makes this the simplest of the local flaps.

The base is never cut, so the vessels that feed the flap stay intact. Because skin bunches when it is pushed forward, small triangles are usually removed along the base so the flap settles flat. Deep stitches take the tension, and the surface layer is closed without strain.

Where this design shines is in scar placement. The lines can be steered into a forehead crease, along a hairline, or exactly on the border between the nose and the cheek, so the repair is far less obvious than a straight closure across the same area would be. Where the nearby skin will not move, though, a different geometry is needed.

Wounds often closed with this flap
✦Forehead wounds left after a skin lesion is removed
✦Upper or lower lip wounds, where the free edge must stay level
✦Cheek defects beside the nose or under the eye
✦Wounds along the rim of the ear
✦Fingertip wounds where padding needs to be restored
✦Scalp wounds with mobile skin on either side

Signs the flap needs urgent review

The far end of the flap turns dark or dusky over the first days.
Swelling under the flap suggests blood has collected beneath it.
The suture line separates, or the flap begins to pull back from the edge.
Spreading redness, fever or pain that keeps rising instead of settling.

When an advancement flap is the right choice

This design works when there is loose, well supplied skin directly next to the wound, and when the resulting scar lines can be hidden in a natural crease or border.

May be suitable when
✦Skin next to the defect is loose enough to move forward without tension.
✦Scar lines can be placed in a wrinkle, a hairline or a facial border.
✦The defect is a reasonably simple shape rather than long and awkward.
✦Blood supply in the surrounding tissue is healthy.
May not be suitable when
✦The nearby skin is tight, scarred or previously treated with radiotherapy, so it will not move.
✦Advancing the flap would drag an eyelid, a lip or a nostril out of position.
✦The defect is large compared with the tissue available beside it.
✦Smoking or poor circulation puts the far end of the flap at real risk.

How the flap is planned and moved

01
Planning the design

The defect is measured and the direction of movement chosen. Lines are drawn so the final scars fall into a crease, a hairline or the border between two areas of the face.

02
Raising the flap

Skin and the layer beneath are then lifted away from the deeper tissue while the base stays attached. Enough is released for the flap to reach the far edge without being stretched.

03
Adjusting the base

Because sliding tissue forward leaves a bunched area behind it, small triangles of skin are usually removed at the base. This lets the flap settle flat against the surrounding skin.

04
Insetting the flap

The flap is advanced into the defect and stitched in layers. Deep sutures carry the tension, so the surface line can be closed neatly and without strain.

05
Dressing and review

Finally a light dressing supports the repair. The flap is checked within a few days, since its colour tells the surgeon how well the blood supply is working.

Recovery after an advancement flap

Day 1 to 3

Swelling and bruising are at their most obvious. The area is kept still and raised where possible, and simple pain relief is usually enough.

Week 1 to 2

Stitches are removed at a time suited to the body area. The flap often feels firm and looks slightly raised at this stage.

Week 6

Most swelling has gone and the scar lines begin to soften. Normal activity is usually back, avoiding anything that stretches the repair.

Month 6 and beyond

Scars fade and any puffiness in the flap gradually settles. Small adjustments, if they are wanted, are considered only once healing is complete.

What this flap can achieve

✦Skin comes from immediately beside the wound, so colour and texture match closely.
✦Movement in a single direction keeps the scar pattern simple.
✦Scar lines can be tucked into creases and borders where they are hard to see.
✦No donor site is needed elsewhere on the body.
✦Most repairs are completed in one sitting, often under local anaesthetic.

What results are realistic

Advancement flaps usually blend well, because the skin comes from right beside the wound. Expect visible scar lines for several months before they pale, along with firmness or puffiness in the flap while swelling settles. Near a lip or an eyelid a slight pull can show early on, and it often eases as the tissue relaxes. A small adjustment is occasionally needed once everything has softened.

Risks to weigh up

Local flap surgery is generally reliable, though the flap lives on the blood supply running through its base, and that is where most problems begin.

Loss of the far end of the flap, most often in smokers or where tension was high.
Bleeding under the flap, which lifts it and can threaten its blood supply.
Infection along the suture lines.
Pulling on a nearby eyelid, lip or nostril, altering its position or shape.
Visible scars, a puffy flap or a small fold of skin at the base needing revision.

Caring for the flap and the surrounding skin

The flap and the lines where the skin was moved both need protection. Keeping tension off the repair is the single most useful thing you can do at home.

✦Avoid stretching the area, and sleep with your head raised after facial surgery.
✦Do not smoke, since tobacco reduces blood flow to the tip of the flap.
✦Keep the suture lines clean and dry as instructed until the stitches come out.
✦Ask before wearing glasses, masks or straps that press on the repair.
✦Once healed, shield the scars from strong sun and begin massage only when advised.

Common misunderstandings

MythA flap is just a bigger stitch up.
In practice

A flap carries its own blood supply and is designed to move tissue. Planning that geometry is what puts the scar where it will show least.

MythFlap surgery always needs general anaesthesia.
In practice

Many local flaps are done under local anaesthetic as day care. Larger repairs, anxious patients and children may still be offered general anaesthesia.

MythThe result is final once the stitches come out.
In practice

Swelling and firmness take months to settle. Judging the outcome too early causes unnecessary worry about a flap that is still changing.

MythAny nearby skin can be moved.
In practice

Skin that is scarred, tight or previously irradiated may not move or survive well, so the design has to respect what the tissue can actually do.

✦Day care under local anaesthetic where suitable, with general anaesthesia available.
✦A written estimate before admission covering surgery, dressings and review visits.
✦Planned scar reviews, with any revision discussed only after healing has settled.

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. The same flap may close a small facial wound or form part of a much larger reconstruction.

You receive a written estimate before admission covering surgery, anaesthesia, dressings and planned review visits. For bands, please see the relevant treatment page or the costs section.

This page describes a technique rather than a treatment, so it carries no price of its own. Cost depends on the wound, the anaesthetic used and the reviews needed afterwards. A written estimate is issued before the surgery date is confirmed.

It is a routine reconstructive repair, and many are done under local anaesthetic as day care. The main concerns are bleeding under the flap, infection and loss of the flap tip. These are checked for at the early review visits.

Desk work is often possible within a few days if the area can be protected. Heavy work, gym sessions and anything that stretches the repair wait longer. The exact timing depends on the site, and recovery can vary.

Lines are placed in creases, hairlines or facial borders wherever the anatomy allows, which makes them far less noticeable than a straight closure. They stay pink and firm for months before fading, so early appearance is misleading.

Some bruising and swelling are expected in the first days. A tip that turns dark or dusky needs review, since it may signal the blood supply is struggling. Report any colour change rather than waiting for the next appointment.

Wounds surrounded by tight, scarred or previously irradiated skin, and those where advancing tissue would drag an eyelid, lip or nostril. Very large defects also need a different design, such as a rotation or transposition flap.

The defect is measured, the options are drawn directly on the skin, and photographs may be taken. Smoking, medicines affecting bleeding and general health are reviewed, then the plan, the likely scar pattern and a written estimate are provided.
