Facing a mastectomy is an experience that touches every part of a woman’s life. It changes how you see your body, how you move through daily routines, and how you think about the future. At Tampa Palms Plastic Surgery, we know that breast reconstruction is not just a medical decision. It is an emotional one. Patients come to us wanting clarity, honesty, and support as they plan the next steps in their recovery.
Tissue expansion is one of the most common approaches used in implant-based breast reconstruction after mastectomy. It does not replace breast tissue or create a breast on its own. Instead, it gradually prepares the chest so a breast implant can be placed in a second stage. For many women, this staged approach feels manageable because it allows healing to happen slowly, with room to adjust to each phase.
Dr. Gerard Mosiello performs tissue expansion as part of implant-based breast reconstruction for patients who have undergone a mastectomy. Whether performed immediately in the hospital alongside your breast surgeon, at either Moffitt Cancer Center or AdventHealth Tampa, or as a delayed reconstruction months or years later, most likely at an out-patient center, when a breast surgeon is not involved, the focus remains the same. We want to help you regain a comfortable, confident silhouette while always being honest about what reconstruction can and cannot achieve.
How Tissue Expansion Works After Mastectomy
During a mastectomy, the breast surgeon removes breast tissue but preserves as much healthy skin as possible. That remaining skin becomes the outer covering for reconstruction, but it is often tight or limited. Tissue expansion helps create the space needed for a breast implant.
A tissue expander is a temporary device placed over the chest wall under the mastectomy skin, sometimes under the muscle. The expanders used in our practice contain a magnetized port, allowing saline to be added during office visits without external valves.
The process happens gradually:
- Stage One: The expander is placed during immediate or delayed reconstruction. A biological matrix may be utilized to cover the expander and allow for more initial filling.
- Expansion Visits: Saline is added slowly over several weeks to stretch the mastectomy skin.
- Stage Two: The expander is removed and replaced with a permanent implant.
The goal is not to grow new breast tissue but to prepare a soft, flexible pocket so an implant can be placed safely. This process supports healing and helps restore a comfortable silhouette after mastectomy.
Why Tissue Expansion May Be Recommended
Every woman’s cancer journey, treatment plan, and reconstruction goals are different. Tissue expansion may be chosen because it allows for a controlled, gradual reconstruction while giving your body time to heal.
Patients often find this approach helpful when their goals include:
- Restoring balance under clothing
- Wearing a bra without an external prosthesis
- Achieving a feminine shape that feels familiar
- Rebuilding confidence after treatment
Tissue expansion may be recommended for women who:
- Are undergoing immediate reconstruction at the time of mastectomy
- Are planning delayed reconstruction after treatment is complete
- Need additional space to accommodate a breast implant
- Have a history of radiation and need a staged reconstruction process
- Prefer implant-based reconstruction rather than flap surgery
We discuss what reconstruction can realistically achieve, including the possibility of asymmetry, changes in sensation, and limitations related to skin elasticity or previous radiation. Our goal is to help you move forward with a plan that feels supportive, honest, and aligned with your medical needs.
Who Is a Candidate for Tissue Expansion in Tampa
Tissue expansion in our practice is performed for women who are rebuilding the breast after a mastectomy. The best candidates are those whose mastectomy skin flaps are healthy enough to tolerate gradual stretching during the expansion process. During your consultation, Dr. Mosiello will evaluate several important elements, such as:
- The quality and elasticity of your mastectomy skin
- Your medical history and any treatments that may affect healing
- Whether the reconstruction will be immediate or delayed
- Your smoking status
- Whether radiation therapy has been completed or is still planned
- The type of mastectomy performed by your breast surgeon
For immediate reconstruction, Dr. Mosiello works closely with the breast surgeon so that both procedures are coordinated for the best possible outcome. For delayed reconstruction, he assesses the chest area, scars, and available skin to determine the safest and most reliable plan.
The Stages of the Tissue Expansion Process
Breast reconstruction using tissue expansion takes place in two main stages, with regular follow-up visits in between. Each stage serves a purpose and is tailored to your comfort and healing pace.
Stage One: Placement of the Tissue Expander
At this stage, the tissue expander is placed under the mastectomy skin, and in many cases this is done immediately after the mastectomy in the hospital. Patients should expect surgical drains, swelling, and a more involved recovery because both surgeries happen during the same operation. Hospital stay and drain care are part of the early healing process.
Gradual Expansion in the Office
After you have healed enough to begin expansion, saline is added to the expander over a series of visits. Each expansion appointment is brief. Most women feel temporary tightness or pressure afterward, which usually settles over the next day. Expansion continues until enough space has been created to place the implant comfortably and safely.
Stage Two: Implant Placement
Once expansion is complete, the second stage is performed as an outpatient surgery. During this procedure, the expander is removed and a permanent breast implant is placed. This stage is usually much easier than the first. Recovery is shorter, and drains are often fewer and required for a shorter time period. Most women feel well enough to resume light activities within a week or two and return to full activity within 6 to 8 weeks.
Recovery Expectations for Reconstruction Patients
Recovery after tissue expansion is very different from what patients experience with elective cosmetic procedures. Immediate reconstruction involves a hospital stay, multiple drains, discomfort along the chest wall, and limits on arm movement during the early weeks. The skin needs time to settle before expansion begins.
During expansion, you will come in regularly for fills, and some tenderness or pressure is normal. Once the implant is placed during the second stage, the recovery tends to be smoother. Swelling and tightness decrease over time, and most women return to daily routines gradually as their comfort improves. We provide detailed instructions for every phase of recovery, including drain care, wound care, activity guidelines, and follow-up appointments.
Frequently Asked Questions About Tissue Expansion in Tampa
How long does the full process take?
Most women finish the expansion phase within two to three months, although this can vary based on comfort, skin response, and radiation history. The implant placement surgery follows once expansion is complete.
Will my reconstructed breast look the same as before?
Reconstructed breasts do not match natural breasts in sensation or feel. The goal is to create a balanced silhouette, restore comfort in clothing, and help you move forward after treatment with confidence.
How does radiation affect expansion?
Radiation can make the skin firmer and less elastic. Some women begin expansion before radiation, while others wait until treatment is finished. Dr. Mosiello will create a plan that fits your oncology schedule.
Is the expansion process painful?
Most patients describe a feeling of pressure or fullness after each expansion rather than sharp pain. Any discomfort usually improves within a day.
Will I need an implant after the expander?
Yes. The tissue expander is always temporary and is replaced with a breast implant during the second stage of reconstruction.
Will there be scars?
Tissue expander reconstruction uses the mastectomy incisions whenever possible. Scars fade over time but remain visible to some degree, which is normal after mastectomy.
Does insurance cover breast reconstruction?
Yes. Federal law requires most insurance plans to cover breast reconstruction after mastectomy. Our office will help verify your benefits and answer any questions.
