Can saline be added to a smaller breast implant 2 years after surgery ? It is under the muscle.

Although it can be done, there is a minimal amount that could be added, and not worth doing. The cost of two new implants will probably be less than $800 of the total cost of the procedure.

The short answer to your question is yes, additional saline CAN be added to a breast implant, even years after the original augmentation.  There is a limit (usually around 30 ml) on how much can be added before the implant becomes unacceptably firm and there is additional rippling.  So, if you are wanting a significant change in size, you will need to have the pocket enlarged and the implants replaced.  This is a relatively straight-forward procedure in someone who also has implants in place.

This can be done to help complete the fill volume on the saline implant or slightly overfill the saline implant.  It is going to require going back to the operating room and is a costly option.  I usually advise patients that if they want to get a fuller look, they should go to a large implant altogether to get a more noticeable difference in the cup size.  Hope that is helpful!
