Some burn defects are too deep for a graft, with bone, tendon or joint exposed at the base. A free flap moves living tissue with its own blood supply into that gap and reconnects it under a microscope.
A free flap moves skin, fat and sometimes muscle from another part of the body, together with its artery and vein, into a burn defect. Those vessels are joined to vessels near the wound under a microscope. Flaps are used when bone, tendon or a joint is exposed and simpler cover would fail, which makes this the most demanding option available.
Grafts survive by taking nourishment from the surface they are laid on. Where that surface is bare bone, exposed tendon or an open joint, there is nothing to nourish them, and no graft or matrix will hold. Tissue that brings its own blood supply answers that particular problem.
The surgeon selects a donor area, commonly the thigh, back or forearm, and raises a block of skin and fat, sometimes with muscle, on its feeding artery and vein. Those vessels are divided, the tissue is moved to the defect and the vessels are stitched to vessels near the wound under a microscope, using sutures finer than a hair. Blood flows again, and from that moment the flap lives on the new connection.
Burn injury complicates this. Vessels within the burned zone may be scarred and unusable, so imaging is often done beforehand to find healthy vessels outside it. Operating time is long, monitoring afterwards is intensive, and the donor site adds its own recovery.
Free flaps suit defects where nothing simpler will work, in patients fit enough for a long anaesthetic. Suitability rests on the wound, the vessels and general health together.
The defect is assessed and the blood supply around it is studied, often with a scan, to find vessels outside the burned zone. A donor area is chosen and marked, and fitness for a long anaesthetic is confirmed.
Scar and dead tissue are cleared until healthy edges are reached. Recipient vessels are exposed and checked, since the whole plan depends on finding a vessel with reliable flow.
A second team commonly raises the flap while the first prepares the site. Skin, fat and sometimes muscle are lifted on the feeding artery and vein, which are then divided.
The tissue is moved into the defect and the vessels are stitched under a microscope. Flow is confirmed, colour is watched, and only then is the wound closed around the flap.
Closure of the donor site follows, either directly or with a graft. The flap is checked at short intervals for the first days, because a problem found early can often be corrected in theatre.
Monitoring is constant. The flap is checked for colour, warmth and refill, the limb is kept still and warm, and fluids and blood pressure are managed carefully to protect the connection.
Monitoring eases as the flap settles. Sitting and gentle movement begin under supervision, and the donor site is reviewed. Discharge follows once both sites look reliable.
The flap is usually stable though still swollen and numb. Therapy focuses on the nearby joints, and garments are considered for the surrounding scar.
Swelling settles slowly and sensation may improve partially. Thinning or contour adjustment of the flap is sometimes planned later, once everything has matured.
A flap restores stable cover rather than normal appearance. Transferred tissue usually differs in colour and thickness and may look bulky at first, settling over months. Sensation returns partially at best. Secondary procedures to thin or reshape the flap are common and are anticipated in the plan. Movement improves where therapy is followed, and the donor area keeps a scar of its own.
This is the most complex option in burn reconstruction and it carries the largest risks. They are explained in detail before consent is taken.
Discharge comes only once the flap looks reliable, and the routine afterwards protects it.
Transferred tissue keeps the colour and thickness of where it came from. It usually looks different and may need thinning later.
Flaps often need secondary procedures to thin, reshape or release them. That is anticipated rather than a sign of a problem.
Sensation returns partially at best. Protecting the area from heat and pressure remains important long afterwards.
Smoking narrows small vessels and directly threatens the connection the flap depends on. Stopping is one of the few things a patient controls entirely.
Complex reconstruction at Elegance Clinic in Surat is undertaken only where simpler cover genuinely will not work, and the reasoning is explained with the alternatives. The scale of the operation and its recovery are described honestly before any decision.
A free flap is the most resource intensive option here, involving long theatre time, two surgical teams in many cases, microsurgical instruments, monitoring after surgery and a longer stay. Secondary procedures to refine the flap are often needed later and are quoted separately. After assessment the office prepares a written estimate and checks what a policy or a government scheme will cover.
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 →Theatre time is long, microsurgical instruments and monitoring are required, two surgical sites are involved and the stay is longer. Secondary refinements are often needed later. An estimate covering the admission is prepared after assessment, and cover under a policy or scheme is checked in advance.
Circulation is checked at short intervals, so a problem is usually caught early and the patient returns to theatre to reopen the join. Where a flap is lost despite that, an alternative plan is made, which may mean another flap or a different form of cover.
It is a long procedure, considerably longer than grafting, and the exact time depends on the defect and the flap chosen. Anaesthetic fitness is assessed with that length in mind. Families are told to expect a long day rather than given a fixed figure.
Longer than for grafting, because the flap needs close observation in the early days and both surgical sites need to settle. Discharge depends on how the flap and the donor area look rather than on a set number of days.
Transferred tissue keeps the colour and thickness of its original site, so it usually looks different and can appear bulky at first. Swelling settles over months and a thinning procedure is often planned later. Stable cover comes first and appearance second.
Wherever a graft, a local flap or a matrix can do the job, that is preferred. A free flap is proposed when bone, tendon or joint is exposed, or when simpler cover has already failed. Alternatives are always discussed first.
The defect is examined, scans of the blood supply are usually arranged and the donor area is discussed and marked. Fitness for a long anaesthetic is assessed. Risks, the monitoring afterwards, likely secondary procedures and a written estimate are explained before consent.
