A rotation flap swings a broad curve of skin around a pivot point and into the defect next to it. Because the flap is wide at its base, it carries a generous blood supply, which makes it useful on the scalp, cheek and back.
A rotation flap is a curved sheet of skin that pivots around a fixed point at its base and turns into the neighbouring defect. The curve has to be considerably longer than the wound it fills, so the tension is spread along a wide arc instead of pulling at one spot. This makes it a good choice for tissue that is thick or does not stretch easily.
Some skin simply refuses to slide. Scalp is a good example, since it is thick, tethered and stretches very little. Pushing such tissue straight forward achieves nothing, so instead a long curved incision is made and the whole sheet of skin is pivoted sideways into the wound. The movement is a turn rather than a slide, and the pivot point sits at one corner of the flap base.
Geometry matters here. The arc has to be far longer than the defect is wide, because tension is shared along the whole curve. A short arc concentrates the pull at the far edge and the flap will not reach, or reaches only under strain that puts its tip at risk. Where more movement is needed, the surgeon can extend the curve or make a small release at the base.
The reward is a robust flap with a broad base and a good blood supply, which is why rotation designs are used on the scalp, the cheek and pressure areas over the hip and lower back. The cost is a long scar, so the curve is planned to follow a hairline, a jaw line or another natural border wherever it can.
Rotation suits defects surrounded by tissue that will pivot but not slide, and situations where a long curved scar can be hidden in a natural line.
The wound is first trimmed into a triangle, since that shape fits neatly inside the curve of the flap. Only tissue that has to go is removed at this stage.
A long curve is then marked from one corner of the defect, following a hairline or natural border where possible. The arc is deliberately much longer than the defect is wide.
Skin and the layer beneath are lifted along the curve, keeping the base broad so the blood vessels feeding the flap are not narrowed.
The flap is turned around its pivot point into the defect and stitched in layers. A small release at the base can be added if the flap does not reach comfortably.
The curved donor line is closed, and a small fold of skin at the pivot is trimmed if needed. A dressing supports the repair until the first review.
Swelling and bruising build and then start to ease. A drain is sometimes used under a large flap, and rest matters most in these first days.
Stitches or staples are removed at a time suited to the site. Scalp flaps often feel tight and numb, which is expected early on.
The curved scar softens and most activity resumes. Pressure areas are protected carefully, since sitting or lying on a healing flap risks breakdown.
Scar lines fade and sensation gradually returns, though some numbness inside the flap can persist. Hair growth across a scalp scar may stay patchy.
The defect is closed with matching tissue, but the trade is a long curved scar that is visible for months before it fades. Numbness within the flap is common early and improves slowly. On the scalp, hair usually grows through the flap itself while the scar line may stay bare. Puffiness and firmness settle over several months, and a fold of skin at the pivot point sometimes needs a small later adjustment.
A rotation flap is a larger undertaking than a simple closure, and the length of the incision brings its own considerations.
The turned flap and the long curved donor line both need protection while healing. Pressure and tension are the two things to avoid.
A wide base actually carries a stronger blood supply. Problems come from tension and short arcs, not from the size of a well designed flap.
Hair usually grows through the flap itself, since hair bearing skin was moved. The scar line often stays bare, which is why it is placed to be hidden.
Some numbness is expected, because small skin nerves are divided when a flap is raised. Sensation often returns slowly over months, though it may not return fully.
The flap closes the wound, but the pressure that caused it remains. Cushions, turning routines and skin checks are as important as the surgery itself.
At Elegance Clinic in Surat, larger flaps are planned with the whole picture in mind, including the pressure relief, nutrition and mobility that decide whether a repair lasts.
Technique pages do not carry their own price, because the cost depends on the treatment the technique is used within. A small cheek rotation and a large flap for a pressure sore involve very different theatre time and length of stay.
A written estimate covering surgery, anaesthesia, any hospital stay, dressings and reviews is given before admission. 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 ranges from a day case on the face to a longer procedure under general anaesthesia for a large pressure sore. Fitness for anaesthesia is assessed beforehand, and the scale of the operation is explained clearly at consultation.
Tension has to be shared along the whole curve for the flap to reach and survive. A short arc concentrates the pull at the tip and risks losing it, so length is a design requirement rather than an oversight.
Light activity often returns within days after a small facial flap, while large flaps need weeks of protection, especially over a pressure area. Sitting and lying routines are adjusted for a time, and recovery can vary considerably.
Hair usually grows through the flap, because hair bearing skin has been moved into the defect. The scar line itself often remains bare, which is why the curve is planned to sit within or near the hairline.
Anyone whose surrounding skin is too scarred or too limited to give a long arc, and anyone in whom a long curved scar would cross a prominent area with nothing to hide it. Poor circulation and continued smoking also weigh against it.
The defect is assessed, the arc is drawn on the skin, and the expected scar is explained. Circulation, smoking, diabetes and mobility are reviewed, and for pressure sores the seating and nursing plan is discussed before a written estimate.
