Synmastia, or symmastia, is a specific type of post-operative issue in women with breast implants that can be addressed with breast surgery revision. Synmastia occurs when one or both implants move too close to the midline of the breastbone, resulting in breasts that are positioned overly close together.

About Synmastia/Symmastia

Synmastia is a less-common breast implant complication that occurs when one or both implants move too close to the midline of the breastbone, or sternum. Women whose breasts touch in the middle, or have skin that is lifted off the breastbone and tents between the breasts, may have synmastia. Women who are experiencing synmastia may also have nipples pointed slightly outward as a result of the shift of the implants to the center of the chest. Synmastia can also be accompanied by mild discomfort around the center of the chest.

Fortunately, synmastia can be permanently corrected. Revision surgery to improve synmastia involves reshaping the implant pocket and repositioning the implant further from the sternum. This is done by rolling and shaping tissue surrounding the implant pocket into a shape that supports the implant before the implant is repositioned into the newly repaired pocket, in a natural position away from the chest center. After, the overlying skin and muscle is sutured from the inside to repair the natural skin covering of the breastbone and to prevent the implants from moving together again.

Some women who undergo breast revision surgery to address synmastia may also choose to switch to a larger or smaller implant size. When performed correctly, the success of the revision surgery should not be affected by the size of the implants, so women may adjust their breast volume as they wish.

Women who are unhappy with their breast augmentation results, or whose implants have shifted or changed over time, are encouraged to consult with Dr. Halls, who specializes specifically in breast enhancement and revision. Many common breast implant complications require a thorough, comprehensive approach and skilled surgical techniques. With the right surgeon, women can enjoy the long-term benefits of their breast augmentation again.

The costs of breast revision surgery for synmastia vary depending on the customized approach that Dr. Halls uses to address your specific needs, and if any other procedures are performed at the same time. Additionally, patients are encouraged to contact their health insurance provider to inquire about possible coverage. While many providers won’t cover the costs of a cosmetic procedure, some do occasionally cover revision surgery. The charges associated with your procedure will be inclusive of Dr. Halls’ surgery fee, the cost for the surgical facility, and anesthesiologist fees. After your consultation Dr. Halls’ staff will discuss surgical costs with you, including information about procedures that may be allowed by your insurance plan or are self-pay, so you can make an informed decision before moving forward.

Recovery & Results

You should notice an immediate difference in the way your breasts look following your revision surgery, but the full results will initially be obscured by swelling. It’s normal to experience some soreness for the first week, but wearing a special surgical bra 24 hours a day for the first few days can help reduce any swelling or discomfort as well as encourage breasts to heal in the proper position. Dr. Halls will provide you with detailed post-operative care instructions and schedule your first follow-up appointment.

Following your revision surgery, your breasts should assume a natural symmetrical placement on each side of the breastbone, leaving a smooth flat space between the breasts and more defined cleavage. With beautiful, naturally positioned breasts, you can once again enjoy wearing clothes you may have avoided before, along with noticing a boost in self-confidence and an improved figure.
