Symmastia after breast augmentation
16.09.2026
Symmastia is loss of the natural cleavage plane because implants move too close together or the medial boundary of the pocket is disrupted. Early postoperative photographs alone are not enough for diagnosis.
How it may look
The cleavage contour becomes indistinct, skin over the sternum lifts or the implants appear connected. Assessment is performed standing, lying down and during muscle contraction.
Why it happens
- over-dissection of the medial pocket;
- implant geometry that exceeds the anatomical base;
- weak tissues or previous surgery;
- healing and loading factors.
Swelling or complication?
Early swelling and high implant position may temporarily make the breasts look closer. Increasing pain, redness or a sudden shape change should be reported to the surgeon.
Revision planning
Correction may rebuild the pocket boundary, change the implant plane or implant and reinforce tissues. This is individual revision breast surgery, not simply an implant exchange.
FAQ
Can a special bra correct symmastia?
It may support early management but cannot repair an established pocket defect.
When can the result be assessed?
Timing varies; revision decisions are generally avoided during active swelling.
Must implants be replaced?
No. It depends on implant geometry, condition and the cause of displacement.
This article is educational and does not replace an examination. The cause of a concern and the appropriate correction method are determined individually during consultation.
