When Will Breast Implant Size and Placement Changes Be Noticeable?

Increasing your breast implant size by 80 cc would give you a bit more fullness but not much of a change in breast size.  In general, when switching from above to below the muscle you must add 50 cc.   Also if you are switching from a saline to a gel implant then an 80 cc would be just about right.

I assume you are staying with same type of implant fill material. Do you have saline or silicone? Saline generally will look larger for a volume change compared to silicone. If you are changing your implants because of rippling, if you have saline, switching to silicone could help this. You should not notice a size increase if you add 30cc of either silicone or saline. With saline you might notice a change at 300cc. If you have saline, the size is easy to control because the fill volume can be varied. Make sure your plastic surgeon has your picture in the OR. When he changes the implants, he/she can sit you up and compare your size to the pre-op picture and make any necessary adjustments to produce the same size. If you have ANY drooping, he/she may have to go slightly larger to take up the excess skin. Implants "fill" the skin more when they are top of the muscle.
Hope this helps.
