Revision Surgery to Correct Minor Double Bubble by Moving the Implants over the Muscle. Rippling Risk?

If your implants are under the muscle, that was probably a choice based on the advantages of muscle coverage. The double bubble results from either lowering the bottom fold of the breast or because of the way the muscle is cut off the ribs; it then attaches to the implant capsule. You can tell if this is the case but noticing if there is upward pulling at the crease when you flex your pecs. If that happens, you need to either go over the muscle, which could result in implant visibility... more

Going over the muscle will increase the visibility of your implants and visibility of any rippling (which is normal with any implants but is more obvious with saline implants, less so with silicone). Depending on how much fat you have (or how skinny you are), the decision of going above or below is something that you should discuss with your PS.  They all have pros and cons.

If you have a double bubble, the fold can be tacked back down. You also may want to lower the volume of the implant.
