Where does the implant go?
Above the pectoralis chest muscle, beneath the remaining skin and soft tissue.
A tissue expander may first create space for an implant. Supporting tissue material may also be used.
Breast & Chest · Reconstruction
Prepectoral Breast Reconstruction
Prepectoral breast reconstruction rebuilds breast shape after mastectomy by placing an implant or tissue expander above, rather than beneath, the chest muscle.
Can it happen during mastectomy?
Sometimes, if the skin has enough blood supply and coverage.
Reconstruction can also be delayed. The plan may change during surgery if the skin is not healthy enough.
Does it avoid all muscle-related discomfort?
It avoids lifting the chest muscle to cover the implant, but recovery still involves discomfort.
It can reduce implant movement caused by muscle contraction. It does not eliminate surgical risks or the possibility of additional procedures.
01 · Overview
Understanding above-the-muscle reconstruction
Prepectoral reconstruction is an implant-based approach used after mastectomy. Unlike subpectoral reconstruction, it leaves the chest muscle in its usual position rather than placing the implant partly or fully beneath it. It is not cosmetic breast augmentation. [1]
The surgeon may place a final implant at the first operation or use a temporary tissue expander that is gradually filled and later exchanged. An acellular dermal matrix—a processed tissue scaffold—or another support material may help support the reconstruction. [2]
Healthy skin with reliable blood supply is essential because the muscle does not cover the implant. Skin thickness, prior surgery, radiation, nicotine exposure, and your broader health affect whether this approach is appropriate. Choosing reconstruction, delaying it, or choosing a flat chest are all valid paths. [1]
- Implant position
- Above the chest muscle
- Reconstruction pathway
- Direct implant or staged expander-to-implant
- Anesthesia
- Usually general anesthesia
- Long-term care
- Follow-up and possible future implant surgery
How is this different from reconstruction using my own tissue?
Prepectoral reconstruction uses an implant, sometimes preceded by an expander. Flap reconstruction moves your own tissue from another area, such as the abdomen, to rebuild the breast. Flaps involve different scars, recovery needs, and long-term considerations.
What if I already have an implant under the muscle?
Some people can have the implant moved above the muscle to address movement or discomfort. This revision may involve muscle repair, supporting tissue material, or fat grafting. Skin coverage and previous radiation help determine whether conversion is reasonable.
02 · Concerns & Goals
What you may want to discuss
Reconstruction is a personal choice. Your priorities, cancer treatment plan, and the health of the remaining breast skin all help guide the discussion.
Breast shape after mastectomy
You may want a breast mound that feels comfortable in clothing. Skin availability and chest shape influence the size and contour that can be created.
Movement when using chest muscles
Implants under the muscle may move or distort with muscle contraction. Above-the-muscle placement aims to limit this effect, though other movement or asymmetry can remain.
Visible edges or rippling
Thin skin may reveal an implant's edges or folds. Your surgeon can discuss whether implant selection, support material, or later fat grafting could improve coverage.
Treatment timing and more surgery
Radiation, chemotherapy, skin healing, and your willingness to undergo staged procedures all matter. A reconstruction plan should fit around necessary cancer care.
03 · Options
How the approaches differ
These pathways may be considered within above-the-muscle reconstruction. Your surgeon will explain which are reasonable for your tissue and treatment plan.
Immediate direct-to-implant reconstruction
A final implant is placed above the muscle during mastectomy.
How it worksThe surgeon evaluates skin blood supply and coverage before deciding whether the implant can be placed safely.
May suitSelected patients with healthy skin coverage and an appropriate planned breast size.
Main tradeoffIt may avoid an expander exchange, but revisions or a change of plan can still be needed.
Staged expander-to-implant reconstruction
A temporary expander is placed above the muscle before a final implant.
How it worksThe expander is filled gradually during office visits and exchanged for an implant in another operation.
May suitPatients who need gradual shaping or more flexibility while treatment and healing progress.
Main tradeoffIt requires expansion visits and another planned operation; the expander may feel firm or uncomfortable.
Delayed prepectoral reconstruction
Reconstruction begins after recovery from mastectomy or other treatment.
How it worksThe surgeon reassesses the healed chest and determines whether an above-the-muscle expander or implant is feasible.
May suitPatients who prefer to wait or need to prioritize treatment or medical recovery.
Main tradeoffScarred, tight, or irradiated skin may limit implant options or make tissue-based reconstruction more suitable.
Conversion from under-the-muscle placement
An existing implant reconstruction is revised to an above-the-muscle position.
How it worksThe surgeon moves the implant pocket and may repair the muscle or add tissue support and fat grafting.
May suitSelected patients with muscle-related implant distortion or discomfort and sufficient tissue coverage.
Main tradeoffRevision introduces new healing risks and may make rippling or implant edges more noticeable.
Supporting tissue material and fat grafting are tools, not guarantees of a better result. Ask why they are recommended and whether they add procedures or risks. [1] [2].
Can I have this if radiation is planned?
Possibly, but radiation can damage skin, tighten the implant capsule, and increase wound and implant complications. Your breast surgeon, plastic surgeon, and radiation oncologist should coordinate timing and discuss whether a flap or delayed approach would better fit your needs.
Is above-the-muscle placement always better?
No. It avoids lifting the muscle and reduces muscle-driven implant distortion, but provides less tissue coverage over the implant. Under-the-muscle placement or reconstruction using your own tissue may be more suitable in some situations.
04 · Results
What may improve and what may remain
Shape and balance
Reconstruction can restore a breast mound, but it does not recreate an unchanged natural breast.
- Differences in height, size, softness, or contour may remain.
- Surgery on the other breast may be discussed for balance.
- Nipple reconstruction or tattooing may be separate later choices.
Movement and sensation
The implant is not directly pulled by the chest muscle, but sensation usually changes after mastectomy.
- Muscle-related distortion may be reduced compared with under-the-muscle placement.
- Numbness or altered sensation can be long-lasting.
- A reconstructed breast may feel firmer or less natural than expected.
Long-term maintenance
Implants are not lifetime devices, and additional surgery may be needed.
- Rippling, scar tightening, aging, or weight changes can alter the appearance.
- Fat grafting or other revisions may be considered after healing.
- Silicone implants need periodic imaging for silent rupture according to current guidance and your care plan.
Your result depends on tissue quality, cancer treatment, healing, and the reconstruction pathway. Discuss both the initial operation and likely future care. [2]
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 depends on whether reconstruction accompanies mastectomy, uses an expander, or revises an existing implant. Your surgical team's instructions should guide wound care, arm movement, and activity.
Step 1 · Day of surgery
Treatment day
The team monitors circulation, pain, and the reconstructed breast. You may have drains and a surgical bra. Going home the same day or staying in the hospital depends on the full operation and your health.
Step 2 · First days to weeks
Early healing
Swelling, bruising, tightness, and fatigue are common. Follow-up checks assess the skin and incisions; drain removal depends on drainage and the team's assessment.
Step 3 · Following weeks
Gradual return
Activity increases as healing allows. If you have an expander, fills begin when the surgeon considers the tissues ready. Returning to work does not mean healing is complete.
Step 4 · Over several months and beyond
Settling and later steps
Scars and shape continue to change. Implant exchange, contour refinements, or nipple procedures may be planned around healing and cancer treatment.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Desk workPlanning context: Often possible within several weeks, but timing varies. [2]What affects it: Fatigue, drains, pain medication, and combined mastectomy can delay return.
DrivingPlanning context: Resume only when cleared and able to control the car safely.What affects it: Sedating medication, limited arm motion, and pain can interfere with emergency maneuvers.
Lifting and exercisePlanning context: Restrictions commonly last several weeks and are individualized. [2]What affects it: Heavy lifting and chest exercise can strain healing tissues even though the implant is above the muscle.
Bathing and swimmingPlanning context: Ask separately about showering and submerging the incisions.What affects it: Open wounds and drains affect when soaking or swimming is safe.
These are planning guides, not clearance to resume an activity. Ask your team about your job, caregiving duties, and exercise routine.
Before your procedure
- Coordinate reconstruction timing with your breast surgery and oncology teams.
- Review medicines, supplements, allergies, and any blood-thinning treatment; change medicines only as directed.
- Discuss all nicotine use and your team's requirements for stopping before and after surgery.
- Arrange transportation and help with children, pets, meals, or lifting.
- Ask what drain care, dressings, and support garments your specific plan may require.
- Confirm follow-up visits, after-hours contact details, and the backup plan if skin circulation is poor.
Does sparing the muscle mean a quick recovery?
Not necessarily. Mastectomy wounds, skin circulation, drains, and additional procedures still need healing time. Some people have less muscle-related discomfort, but the overall recovery remains individual.
How should I manage swelling or discomfort?
Use only the medicines and comfort measures approved for your operation. Ask your surgical team whether compresses are appropriate and exactly how to use them. Numb skin can be injured without you noticing.
06 · Safety
Risks and what your clinician assesses
Early soreness, swelling, bruising, tightness, fatigue, and altered sensation are common. Symptoms should generally improve; new or worsening changes deserve a call rather than being assumed to be normal.
Skin or wound-healing problems
Poor blood supply can cause skin or nipple tissue loss, wound opening, or implant exposure. Treatment may require additional surgery or implant removal.
Infection
Infection may require antibiotics, drainage, or removal of the expander or implant. It can interrupt the reconstruction timeline.
Bleeding or fluid buildup
Blood or clear fluid may collect around the reconstruction and sometimes requires drainage or another operation.
Scar tightening and contour changes
Capsular contracture can make the breast firm or painful. Rippling, visible edges, implant shifting, and asymmetry may require revision.
Implant-related complications
Implants can rupture or deflate. Rare cancers, including BIA-ALCL, have been associated with the implant capsule; BIA-ALCL occurs more often with textured implants. Ask about implant surface and symptoms to watch for.
Anesthesia, clots, and persistent symptoms
Surgery carries anesthesia and blood-clot risks. Persistent pain or altered sensation can occur, and reconstructive failure may require a different approach.
Discuss these risks and your individual health history with your surgeon. [3]
What your clinician assesses
- Skin thickness, blood supply, scars, and available soft-tissue coverage.
- Previous or planned radiation, chemotherapy, and mastectomy details.
- Nicotine exposure, diabetes, clotting history, and other conditions affecting healing.
- Desired size, activity needs, expectations, and willingness to have future procedures.

08 · Questions
Common questions
Will I still need breast cancer follow-up?
Yes. Reconstruction does not replace cancer surveillance. Your oncology team determines examinations and imaging based on your history and remaining breast tissue. Imaging to check an implant is different from cancer screening.
Can the nipple be preserved?
Sometimes nipple-sparing mastectomy is possible, but cancer safety and blood supply determine eligibility. Preserving the nipple does not guarantee normal sensation or survival of the nipple tissue.
Will I be able to breastfeed from the reconstructed breast?
A breast reconstructed after mastectomy generally cannot produce milk because the milk-producing tissue has been removed. An untreated breast may still be able to breastfeed, depending on other treatments.
Can I change my mind about implants later?
Yes. Implant removal, flat closure, or reconstruction using your own tissue may be options. Each requires a new assessment, and previous surgery or radiation can affect what is possible.
