Reconstructive Surgery
Free flap reconstruction moves living tissue from one body area to another, reconnecting tiny blood vessels to restore coverage, shape, or function.
What makes this a free flap?
The tissue is completely detached and its blood vessels are reconnected at the reconstruction site.
A pedicled flap stays attached to its original blood supply. A skin graft does not include its own connected blood supply.
Where can it be used?
Free flaps can reconstruct the breast, head and neck, limbs, and other areas.
The transferred tissue may contain skin, fat, muscle, bone, or a combination, depending on the defect.
What should I plan for?
Major surgery, a hospital stay, and recovery at both the reconstruction and donor sites.
Close blood-flow monitoring is especially important early on. Your surgeon will explain the likely stay and restrictions for your particular flap.
01 · Overview
A free flap brings living tissue and its blood supply to an area that needs reconstruction. Using magnification and fine instruments, the surgeon connects the flap's arteries and veins to nearby vessels so blood can circulate through the transferred tissue. [1]
The flap is chosen to replace the tissue that is missing. Skin and fat may restore coverage and volume; muscle may help fill a deeper space; bone may rebuild structural support. The best donor area depends on the reconstruction, available blood vessels, previous operations, and your health. [2]
This is not simply a skin graft or a cosmetic tissue transfer. It creates two surgical sites and requires specialized monitoring. Consultation should cover the intended benefit, the effect on the donor area, alternatives, and what would happen if the flap developed a blood-flow problem. [1]
Nearby tissue may be missing, scarred, damaged by radiation, or unable to provide enough coverage. A free flap can bring tissue from farther away, but it also adds microsurgical complexity and donor-site recovery.
No. Reconstruction may happen immediately or after another stage of treatment. Infection control, cancer treatment, wound condition, and overall health can affect timing.
02 · Concerns & Goals
Cancer treatment, injury, infection, or another condition can leave an area needing healthy tissue. The plan depends on what is missing and what matters most to you.
A deep wound may expose bone, tendons, hardware, or other structures that need healthy tissue coverage.
Transferred tissue can help rebuild an area removed during treatment or lost through injury.
Some reconstructions require bone or other supporting tissue, not just skin coverage.
Reconstruction may support goals such as walking, swallowing, speaking, or using a limb. The achievable benefit depends on the underlying damage.
03 · Options
Free flaps are selected by the tissue needed and the safest suitable donor area. These categories can overlap; your surgeon may combine tissue types in one flap.
Transfers soft tissue to restore coverage or volume.
Uses vessels that pass through or between deeper tissues while preserving underlying muscle.
Transfers muscle, sometimes together with skin.
Transfers living bone, sometimes with skin or muscle.
A flap name alone does not tell you whether it is the right choice. Ask what tissue will be moved, what will be preserved, and how both surgical sites may be affected. [1] [2].
In selected reconstructions, nerves may also be connected to support sensation or movement. Nerve recovery is slow and uncertain, and normal sensation or function may not return.
Previous surgery, scars, vessel anatomy, or circulation problems may rule out a donor area. Your surgeon may discuss another free flap, a different reconstruction method, or a staged approach.
04 · Results
The goal is living tissue that heals into the reconstructed area.
Functional improvement depends on the original problem and the tissues involved.
Both the reconstructed area and donor site need follow-up.
Results vary with the flap, circulation, original defect, health conditions, and any radiation or other treatment. Your surgeon can explain which goals are realistic for you. [1]
05 · Recovery
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery is individualized because a breast, jaw, or limb flap can require very different precautions. Your team's instructions for both surgical sites take priority over general timelines.
Step 1 · Day of surgery
After reconstruction, staff monitor your recovery from anesthesia and check the flap's circulation. You may have dressings, drains, and monitoring equipment.
Step 2 · Early postoperative days
The team checks blood flow frequently and helps with pain control, nutrition, and safe movement. A circulation problem may require urgent return to the operating room.
Step 3 · After discharge
You receive a plan for wound care, any drains, activity limits, and follow-up. Help with daily tasks may be needed, especially when both surgical areas limit movement.
Step 4 · Following weeks to months
Activity progresses as healing allows. Therapy, scar care, and discussion of later revisions may continue well after you return to work.
Returning to work is not the same as complete healing. Ask your team for written restrictions that address both surgical sites and your usual activities.
Staff may assess the flap's color, temperature, and circulation and use a Doppler device or another monitoring method. Some flaps are buried under skin and need a different monitoring plan.
Pressure and positioning rules depend on where the flap and its vessel connections lie. Ask specifically about sleeping, sitting, clothing, braces, and any compression garments; do not assume ordinary postoperative compression is appropriate.
Possibly. If drains are needed, your team will explain their care, what to record, and when to call. Removal depends on your recovery rather than a fixed date.
06 · Safety
Swelling, bruising, soreness, fatigue, scars, and altered sensation can occur at both surgical sites. Your team should explain the expected pattern and which changes need prompt assessment.
A clot or another circulation problem can threaten the transferred tissue. Urgent surgery may help restore flow, but part or all of the flap can still be lost.
Blood or fluid can collect at either site. Treatment may include drainage, another procedure, or, in some cases, transfusion.
Infection, wound separation, or tissue breakdown can require medicines, wound care, or further surgery.
Possible effects include weakness, numbness, pain, contour changes, or reduced function. Abdominal donor sites can develop a bulge or hernia.
Scars, firmness, asymmetry, altered sensation, chronic pain, or incomplete functional recovery may persist. Revisions may be needed.
Major surgery carries risks such as breathing or heart problems and blood clots in the legs or lungs. Your individual risk depends on your health and the operation.
Discuss these risks and your individual health history with your surgeon. [1]
07 · Costs
Compare written estimates for the same planned scope, including the reconstruction, donor-site surgery, hospital stay, and expected follow-up. Coverage and personal costs depend on the indication, insurance plan, and participating clinicians and facilities.
Surgeon
Surgeon services for flap harvest, microsurgery, reconstruction, and any planned supporting procedures.
Ask your surgeonAsk which surgical teams are included and whether staged procedures or revisions are estimated separately.
Facility
Anesthesia, operating-room services, hospital care, and postoperative monitoring.
Ask your surgeonConfirm network status, expected admission arrangements, and how an extended stay or return to surgery would be billed.
Supplies
Items such as dressings, medications, equipment, office visits, and rehabilitation when prescribed.
Ask your surgeonAsk which services are included and which may come from separate providers.
TRC
Any separately offered care-coordination or administrative support.
Ask TRCAsk whether these services apply to your plan, whether they are optional, and whether a separate fee applies.
Your written estimate should explain the services included, any separate charges, and payment terms.
08 · Questions
It transfers your own tissue rather than tissue from another person. Anti-rejection medication is generally not needed for the flap itself.
Removed tissue generally does not regrow in its original form. The area heals with a scar, and its shape or function may change. Donor selection aims to balance reconstruction needs with those effects.
The team may attempt urgent surgery to restore blood flow. If the flap cannot be saved, damaged tissue may need removal, followed by wound care or another reconstruction. Ask about the backup plan before surgery.
Sometimes. These treatments may make healthy transferred tissue useful, but they can also affect blood vessels and healing. Your surgeon may need imaging or a different donor or recipient site.
