What does TUG mean?
Transverse upper gracilis.
The flap includes upper inner-thigh skin and fat, the gracilis muscle, and its blood vessels.
Breast & Chest • Reconstruction
TUG Flap Breast Reconstruction
TUG flap breast reconstruction creates a breast shape using skin, fat, and a small muscle from the upper inner thigh.
Is this an implant procedure?
It primarily uses your own tissue.
The tissue is moved to the chest, where its vessels are connected to a new blood supply using microsurgery.
Who might consider it?
Someone with suitable thigh tissue who wants tissue-based reconstruction.
It may be considered when abdominal tissue is unavailable or less suitable. A reconstructive surgeon must assess your options.
01 · Overview
Understanding TUG flap reconstruction
TUG reconstruction transfers living tissue from the upper inner thigh to the chest to rebuild a breast after mastectomy. Unlike a pedicled flap, it is completely detached before its blood vessels are reconnected under magnification. [1]
The flap includes the gracilis, a long, slender inner-thigh muscle. Other leg muscles usually compensate for its removal, but strength, comfort, and mobility can still change. The donor scar generally follows the upper inner-thigh crease and may extend beyond it. [1]
TUG reconstruction is different from a PAP flap, which uses thigh skin and fat without taking the gracilis muscle, and a DIEP flap, which uses abdominal tissue. The right choice depends on your anatomy, medical history, cancer treatment, and preferred breast size. [1]

Why choose the thigh rather than the abdomen?
You may have limited abdominal tissue, previous surgery that affects the available blood vessels, or a preference to avoid abdominal surgery. Your surgeon compares the tissue available at each site with the breast volume you hope to achieve.
Can reconstruction happen at the time of mastectomy?
Sometimes. TUG reconstruction may be immediate or delayed. Radiation plans, cancer treatment, your health, and the availability of a microsurgical team all influence timing.
02 · Concerns & Goals
What you may want to discuss
Your goals may include rebuilding a breast shape, feeling more comfortable in clothing, and understanding what surgery could mean for your thigh.
Replacing breast volume
A thigh flap provides a limited amount of tissue. Ask whether it can create your preferred size without an implant or additional procedures.
Thigh scars and contour
Removing tissue changes the inner-thigh contour and leaves a permanent scar. Unevenness, tightness, or scar widening may occur.
Walking and leg strength
Early walking can feel uncomfortable, and some people notice weakness or pulling. Discuss your work, sports, and any existing leg problems.
Sensation and symmetry
Reconstruction does not restore the original breast or its normal sensation. Differences in shape, size, and feeling can remain.
03 · Options
How the approaches differ
These are planning choices within TUG reconstruction. Your surgeon will explain which are feasible for your anatomy and treatment plan.
Immediate TUG reconstruction
Reconstruction during the same operation as mastectomy.
How it worksThe breast and microsurgical teams coordinate tissue removal and flap transfer.
May suitPeople whose cancer treatment and health allow a combined operation.
Main tradeoffThe initial operation is substantial, and later radiation may affect the reconstruction.
Delayed TUG reconstruction
Reconstruction after mastectomy and, when needed, other treatment.
How it worksThe flap is transferred during a separate operation once timing is appropriate.
May suitPeople who need or prefer to complete other treatment first.
Main tradeoffIt requires another major operation, and chest scarring or radiation changes may affect planning.
One-sided TUG reconstruction
A thigh flap rebuilds one breast.
How it worksThe surgeon selects a donor thigh and shapes its tissue to suit the chest.
May suitPeople needing reconstruction on one side with enough suitable donor tissue.
Main tradeoffDifferences between the thighs or breasts may remain; balancing surgery may be discussed.
Two-sided TUG reconstruction
Thigh tissue is used to reconstruct both breasts.
How it worksTypically, each thigh supplies a flap for one breast.
May suitPeople needing both breasts reconstructed who have adequate tissue and suitable vessels.
Main tradeoffBoth thighs must heal, and the operation and recovery may be more demanding.
Available tissue may limit breast size. Fat grafting, reshaping, or a different reconstruction method may be discussed rather than assuming a TUG flap can meet every volume goal. [1].
Could I need more than one operation?
Yes. Later procedures may adjust shape, improve symmetry, add volume with fat grafting, or reconstruct a nipple. These are separate decisions, not guaranteed parts of every plan.
Does taking the gracilis muscle cause disability?
Other muscles usually compensate, but recovery and long-term function vary. Ask how muscle removal could affect your particular activities and whether a muscle-sparing alternative is suitable.
04 · Results
What may improve and what may remain
Breast shape
Your own tissue can create a breast mound, but matching is not exact.
- Shape settles as swelling decreases and tissue softens.
- Available thigh tissue influences achievable volume.
- Nipple and areola reconstruction may require a later step.
Donor-thigh changes
The thigh heals with a permanent scar and a changed contour.
- Scars generally fade but do not disappear.
- Tightness, numbness, or contour differences may persist.
- Leg function and comfort should be reviewed during follow-up.
Long-term expectations
The reconstructed breast can change with your body over time.
- Weight changes and aging can affect shape and size.
- Normal breast sensation is not reliably restored.
- Revision surgery may be considered, but cannot guarantee symmetry.
Reconstruction does not treat cancer or replace oncology follow-up. Ask your cancer team what surveillance is needed for your remaining breast tissue and reconstructed breast. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery involves both the chest and the thigh. Your team's instructions should reflect the number of flaps, wound healing, mobility, and any additional treatment.
Step 1 · Surgery and early monitoring
Treatment day
After general anesthesia, staff closely monitor the flap's blood supply. Dressings, drains, and assistance with movement are commonly needed.
Step 2 · The first several days
Hospital recovery
The team checks the flap and wounds, manages pain, and helps you begin safe movement. Discharge depends on flap stability, mobility, and your support at home.
Step 3 · The following weeks
Healing at home
Fatigue, swelling, and thigh tightness can continue. Follow your individual plan for drains, wound care, positioning, clothing, and activity.
Step 4 · Over subsequent weeks and months
Gradual return
Activity increases as your surgeon confirms healing. Swelling and scars continue to change after you return to work or daily routines.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Walking and stairsPlanning context: Usually introduced with assistance early in recovery. [2]What affects it: Thigh discomfort, balance, and wound tension determine how quickly you progress.
Desk workPlanning context: Often requires several weeks away, with timing individualized. [2]What affects it: Fatigue, prolonged sitting, drains, and commuting may delay a comfortable return.
DrivingPlanning context: Resume only when cleared and able to control the vehicle safely.What affects it: Sedating medicines, limited movement, and difficulty braking can make driving unsafe.
Lifting and exercisePlanning context: Return gradually after specific clearance. [2]What affects it: Chest strain and stretching across the thigh incision can stress healing wounds.
Returning to work is not the same as complete healing. Follow your surgical team's instructions rather than a general timetable.
Before your procedure
- Discuss previous operations, blood clots, radiation, and any problems with walking or leg strength.
- Review all medicines, supplements, and hormones; change them only as directed.
- Discuss nicotine use and the team's requirements for stopping before and after surgery.
- Ask whether donor-site imaging or other testing is needed.
- Arrange transportation, household help, and support with children or dependents.
- Get a written plan for hospital discharge, wound care, follow-up, and urgent contact.
Will I need special garments or positioning?
Possibly. Pressure over the flap or thigh incision may need to be avoided, while other areas may need support. Use only the garments and positions recommended by your surgical team.
What if sitting pulls on my thigh incision?
Tell your team. They can recommend positions and activity limits suited to your wound. Increasing pain, wound separation, or drainage needs assessment rather than simply changing how you sit.
06 · Safety
Risks and what your clinician assesses
Early swelling, bruising, fatigue, soreness, numbness, and pulling around the thigh incision are common. These should generally improve; new or worsening symptoms deserve a call to your team.
Blood-supply problems or flap loss
A clot or circulation problem can threaten part or all of the flap. Urgent surgery may be needed, and the reconstruction may not be salvageable.
Bleeding or fluid collections
Blood or fluid can collect in the chest or thigh and may require drainage or another procedure.
Infection or delayed healing
Either surgical site can develop infection or wound separation. The upper-thigh incision can be vulnerable to moisture, friction, and tension.
Fat necrosis and shape differences
Some transferred fat may lose its blood supply and form firm areas. Unevenness or contour changes may need evaluation or revision.
Thigh symptoms and scarring
Persistent numbness, pain, weakness, tightness, swelling, or widened scars can occur at the donor site.
Blood clots and anesthesia complications
Major surgery carries risks including leg or lung blood clots and heart, breathing, or anesthesia-related problems.
Discuss these risks and your individual health history with your surgeon. [3]
What your clinician assesses
- Thigh tissue volume, skin quality, blood vessels, and previous scars
- Chest skin, radiation history, and current cancer treatment plans
- General health, nicotine exposure, clotting history, and healing risks
- Preferred breast size, leg function, home support, and tolerance for additional surgery

08 · Questions
Common questions
Is TUG reconstruction the same as a thigh lift?
No. Its purpose is to provide tissue for breast reconstruction. It changes the donor thigh, but the incision and tissue removal are planned around the flap's blood supply rather than cosmetic thigh-lift goals.
Can I have a TUG flap after radiation?
It may be an option. Radiation affects chest skin and tissues, so your surgeon and oncology team must review timing, wound risks, and the available blood vessels.
Will the reconstructed breast feel natural?
It uses your own tissue and may soften over time, but touch and sensation differ from an unoperated breast. Numbness may be lasting.
What happens if the flap fails?
The team may attempt urgent surgery to restore circulation. If the tissue cannot survive, some or all may need removal. Another flap, an implant, or no further reconstruction may be discussed after recovery.
