Microsurgery / Free Flap

Moves tissue from one part of the body to another with its blood vessels reconnected under a microscope, rebuilding areas that simpler surgery cannot restore.

What is microsurgery / free flap surgery?

Microsurgery, or free flap surgery, transfers skin, fat, muscle, or bone from a donor area to a defect elsewhere, reconnecting tiny blood vessels under an operating microscope so the transferred tissue lives in its new location. It is used when a defect is too large or complex for a local flap or graft — after cancer removal, trauma, or in breast reconstruction — and when the tissue must carry its own blood supply to survive.

How is microsurgery / free flap surgery done?

The surgeon removes the chosen tissue with its artery and vein, prepares the defect, and reconnects the vessels to vessels near the defect using sutures finer than a hair, under magnification. Blood flow is checked before and after transfer, and the tissue is shaped into the defect. Surgery is long, often six to twelve hours, under general anesthesia, in a hospital, with monitoring of the flap's circulation afterward — often in an intensive care or specialized unit for the first days.

What are the options for microsurgery / free flap surgery?

Free skin and fat flaps. For soft-tissue defects, including breast reconstruction (such as DIEP flaps) and lower-limb coverage. Free muscle flaps. For defects needing bulk or functional muscle, sometimes with a nerve connection to restore movement. Free bone flaps. For jaw, limb, or other bony defects, often with skin attached. Replantation. Reattaching a severed finger, hand, or other part, which is microsurgery under emergency conditions and succeeds only in selected cases.

What affects the cost of microsurgery / free flap surgery?

There is no single fixed charge for microsurgery / free flap surgery, and this guide does not publish prices: the written quote you receive at consultation is the binding figure.

Factors that commonly move the total include the surgeon's experience, the facility type (office procedure suite, ambulatory surgery center, or hospital), the type and length of anesthesia, the complexity of the surgical plan, whether other procedures are combined in the same operation, garments and follow-up visits, and the revision terms. Ask for an itemized written quote that states exactly what is included, and what would cost extra if a revision or an overnight stay became necessary.

What is recovery like after microsurgery / free flap surgery?

Expect a hospital stay of several days, with the flap monitored closely for circulation problems in the first days — the period when a failing flap can sometimes still be saved. Drains, dressings, and donor-site soreness are part of recovery, and full activity resumes over six to twelve weeks depending on the flap and donor site. Follow-up is frequent at first, then spaced out as the flap settles.

What are the risks of microsurgery / free flap surgery?

Risks include partial or total flap loss if the reconnected vessels clot or fail, bleeding, infection, donor-site problems (weakness, hernia, or scarring depending on the donor area), and prolonged anesthesia risks in a long operation. Flap loss is uncommon in experienced hands but is the defining risk of the operation, and it may require a second reconstruction. Choosing a surgeon and center with substantial microsurgical volume matters more here than in almost any other field.

What should I ask at a microsurgery / free flap surgery consultation?

• Which flap fits my defect, and what will the donor site lose?
• What is your center's experience with this specific flap?
• What happens if the flap fails, and what is the backup plan?
• What is the total quote, broken down, and what are the revision terms?
• Can you confirm your board certification? (Check the badge on each profile in this directory.)
