What a double bubble is
A double bubble deformity is exactly what it sounds like: two visible bulges in the lower breast separated by a horizontal crease, instead of one smooth curve. The implant sits in one position and the natural breast tissue or the original breast crease sits in another, so the breast looks like it has a second fold running across it. It's a contour problem, most visible from the side or when the breast is viewed in profile.
Why it happens
Double bubble usually comes from a mismatch between the implant's position and the breast's natural inframammary fold (the crease under the breast). There are a few common scenarios:
- Implant sitting below the natural fold — if the implant descends below the original crease (related to bottoming out), the old fold remains visible as a line across the breast while the implant bulges below it.
- The natural fold wasn't released — if a tight or high original crease isn't properly addressed during surgery, it can persist as a band across the implant.
- Tuberous or constricted breasts — in breasts with a constricted lower pole or a tight, high fold, the underlying anatomy predisposes to a double bubble unless specifically corrected during augmentation.
So a double bubble is essentially the natural crease and the implant ending up in two different places.
How double bubble is corrected
Correction depends on the cause, but the goal is always to get the implant and the breast crease into a single, harmonious position. Techniques include:
- Reinforcing or repositioning the fold — internal sutures (capsulorrhaphy) rebuild the inframammary fold in the correct position, particularly when the implant has dropped below it.
- Releasing a persistent crease — surgically releasing the old constricting band so the tissue redrapes smoothly over the implant.
- Adjusting the implant pocket — sometimes the implant pocket is revised, or the implant is moved to a different plane, to align everything.
- Soft-tissue measures — fat grafting can help blend and smooth the contour across the crease.
- Treating the underlying constriction — in tuberous/constricted breasts, the lower pole is expanded and reshaped as part of the correction.
Why it needs an experienced revision approach
Double bubble is one of the more technically nuanced revision problems, because the right fix depends on correctly diagnosing why the two creases exist — a dropped implant, an unreleased fold, or constricted anatomy each calls for a different solution, and sometimes more than one applies. Reinforcing the fold without addressing an underlying constriction (or vice versa) gives a poor result. This is precisely the kind of contour problem that benefits from a surgeon who does revision regularly; you can see the general approach on our what is breast revision and implant malposition pages.
The bottom line: a double bubble is the natural crease and the implant sitting in two different places. Correcting it means diagnosing why — then realigning the fold, the pocket and the tissue so the lower breast reads as one smooth curve.
