A seroma is an accumulation of serous fluid, a clear, watery liquid produced by the body's natural healing response, in the space around a surgical site. After breast augmentation, seromas most commonly develop in the pocket created to house the implant, or along the incision line. While seromas are one of the more common post-surgical complications, they are generally manageable and rarely cause long-term problems when addressed promptly.
Symptoms of a Seroma After Breast Augmentation
Seromas most often develop within the first 2–6 weeks after surgery. Signs to watch for include:
- Noticeable swelling or puffiness in one breast that is more pronounced than the other
- A feeling of fluid movement or sloshing in the breast
- A soft, fluctuant (movable) mass near the incision or around the implant
- Skin that appears stretched or tight over the affected area
- Mild discomfort or pressure, pain is usually minimal unless the seroma is large
How Seromas Are Treated
Small seromas often resolve on their own with time and compression. Larger or persistent seromas require aspiration, a simple in-office procedure in which a needle is used to draw out the accumulated fluid. This may need to be repeated once or more until the fluid stops accumulating. In rare cases of recurrent seroma, a surgical drain may be placed temporarily. The fluid itself is sterile and not a sign of infection unless accompanied by fever, redness, or warmth.
What Causes Seromas?
- Disruption of lymphatic channels during surgery (a normal part of the healing process)
- Excessive movement too soon after surgery, which increases fluid production
- Large implant pockets relative to implant size
- Surgical technique, textured implants historically had higher seroma rates
- Prior radiation to the breast area
How Surgeons Minimize Seroma Risk
Experienced surgeons take specific steps to reduce seroma risk: careful hemostasis (control of bleeding) during surgery, precise pocket creation, compression garments worn immediately post-operatively, and patient education about activity restrictions. Following all post-operative instructions, especially regarding lifting restrictions and compression wear, is one of the most effective things a patient can do to reduce their seroma risk.
