Can Double Bubble Be from Swelling and Go Away over a Few Months?

Double bubble can be temporaraily caused by swelliing, edema or hematoma. I would use a reinforcement along the crease.

Thank you for your question. Hopefully the swelling you see is simply tissue swelling or fluid collection. However if it is a true double bubble with displacement of the implant below the inframammary crease it is unlikely to heal and will most likely require revision

What YOU are referring to as "Double Bubble" may or may not be a double bubble deformity. Without a photograph, none of us can confirm it.

A Double Bubble is the demonstration of residual tissue memory in which the incompletely released, persistent constriction of the breast fold indents the lower pole of the breast implant. If this is very pronounced, it will not get better with time and would require surgery to release the breast fold arc. If it is swelling, it should resolve by 6-8 weeks after surgery.

Discuss this with your surgeon.
