Background: Breast implant surgery is all about, of course, making breasts bigger. But patient satisfaction comes from achieving or getting close to what size the patient wants. While breast implants come in a wide range of sizes, there is no exact method of picking an implant and achieving a certain size. This is because, while the implants are consistent in size and shape, women’s chests and breasts are not. What the implant goes into has a lot to do with what it will look like after.
Most breast implant size dissatisfaction comes from still being too small, only very rarely too big. While most women would be content to live with a breast augmentation result that does not meet their ideal breast size goals, a women who would do so usually needs a much more substantial result. With implants in place and seeing what it has created provides a good guide for how much more volume is needed. Changing breast implants is about volumetric size change.
Case Study: This 29 year-old female originally had saline breast implants placed under the muscle through a lower fold incision three years previously. She was never happy with her size and felt that her breasts were not that much bigger than before surgery. She had received 350cc saline moderate plus profile implants and this gave her a breast size of a full B in her opinion. She wanted a full D cup result.
She subsequently had her implants replaced with 500cc high profile silicone gel devices, a 150cc change or 42% increase in volume. Surprisingly, this increased her size somewhat but much less than expected, making her more like a C cup. She was still not happy with the size.


Case Highlights:
1) Selecting the size of a breast implant to get a specific bra size is not an exact science.
2) An indwelling implant provides a guide as to how much volume increase is needed to achieve a specific breast size.
3) A visible change in outer breast appearance requires a minimum of a 30% to 40% volume increase in ccs to be worth the effort of implant exchange surgery.
