A transposition flap is lifted from beside the wound and moved over a bridge of untouched skin into the defect. This lets the surgeon borrow looseness from a different direction, which is useful when the skin right beside the wound will not move.
A transposition flap is a tongue of skin raised next to a defect and swung over the skin in between to reach it. Unlike an advancement flap, the tissue does not slide straight forward, so looseness can be borrowed from whichever direction has it. The donor area is then closed directly, or occasionally covered with a graft.
Skin is not equally loose in every direction. Beside a wound the tissue may be fixed, while a short distance away it pinches easily between finger and thumb. A transposition flap exploits that difference. A tongue of skin is marked out over the loose area, raised while its base stays attached, then swung over the strip of untouched skin in between and stitched into the defect.
Two things then have to work at once. The flap must reach the wound without stretching, and the space left behind must close. That donor closure is really the heart of the design, because it decides where the flap can be taken from. Surgeons therefore plan backwards, finding the direction of maximum looseness first, and letting the flap follow.
As the flap pivots, a small cone of skin tends to gather at the base. It can be trimmed at the time or reviewed later once the swelling has gone. Long narrow flaps look tempting because they reach further, but blood has to travel the whole length, so a broad base is safer than a slim one.
This design suits defects where the loose skin lies at an angle rather than directly alongside, and where the donor area can then be closed as a neat line.
Before anything is drawn, the surgeon pinches the skin around the wound to find the direction that gives most easily. That direction decides where the flap will come from.
A tongue of skin is then marked beside the defect, with the base kept broad. A template of the wound is used so the flap is neither too small nor unnecessarily large.
The flap is lifted with the tissue layer beneath it and swung over the intervening skin into the defect. Its base is never cut, so the blood supply remains intact.
The space left behind is closed directly as a line, or covered with a small graft when direct closure would pull too hard on the surrounding tissue.
Any fold of skin at the pivot is trimmed if it is safe to do so, and a light dressing supports both repairs until the first review.
Swelling and bruising are expected across both the flap and the donor line. The area is kept still and raised where the site allows.
Stitches come out at a time suited to the body area. The flap may look firm, pink and slightly puffy while it settles.
Scar lines soften and normal activity resumes. Any fold at the pivot point is easier to judge now that swelling has gone.
Colour evens out and puffiness usually reduces. Where a raised area persists, a small revision can be discussed at this stage.
Because the tissue comes from nearby, the closed defect usually blends well in colour and thickness. The scar pattern is more complex than a straight line, so expect several visible lines that fade over months. A puffy area within the flap, sometimes called a trapdoor look, is common early and often settles. A small fold at the pivot point may remain and can be trimmed later if it bothers you.
The flap depends on blood flowing through its base, and the design creates two areas that must heal at once.
Two closures need attention here, the flap itself and the line where the skin was borrowed. Both should be kept clean and free from pulling.
Moving tissue sideways creates a pattern of lines rather than one. Each is planned to sit in a crease or border, but the pattern is more complex than a simple closure.
Early firmness and a slightly raised flap are common while swelling and scar tissue mature. Most settle over months, and revision is considered only after that.
Blood has to travel the whole length from the base. Long narrow flaps are the ones most likely to lose their tip, so a broad base is safer.
The donor closure decides the whole design. If that area cannot be closed comfortably, a different flap is chosen from the start.
At Elegance Clinic in Surat, the donor area is planned before the flap, because a repair is only as good as the closure it leaves behind.
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 skin cancer defect or form one step of a larger reconstruction.
Before admission you receive a written estimate covering surgery, anaesthesia, dressings 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.
Ask your question →There is no separate price for a technique, since it forms part of a wider treatment. Cost depends on the size of the defect, the anaesthetic and the number of reviews. A written estimate is given before the surgery is booked.
Most are day case repairs with a well understood risk profile. The concerns are bleeding beneath the flap, infection and loss of the flap tip, which is why an early review is arranged to check the colour of the tissue.
Because looseness is not equal in every direction. If the skin immediately alongside is fixed, borrowing from an angle allows the defect to close without tension, which gives the flap a much better chance.
Stitches usually come out within a fortnight depending on the site, and desk work often resumes within days. Swelling and firmness in the flap take months to settle, and recovery can vary between people.
It is common for the flap to sit slightly proud and feel firm for the first months. Most of that settles as scar tissue matures. If a raised area persists, a small adjustment can be discussed later.
Anyone whose surrounding skin offers no direction of looseness, since the donor area could not then be closed. Heavily scarred or irradiated skin, and designs needing a long narrow flap, also point towards a different repair.
The skin around the defect is assessed for looseness, the design is drawn on the surface, and both the flap and donor scars are explained. Smoking, medicines and general health are reviewed before a written estimate is issued.
