Different Breast Implant Sizes for Slightly Asymmetrical Breasts?

In cases of breast reconstruction after a mastectomy we often place different sized implants to improve assymetry.

However, please understand that more than 1/2 of all cosmetic surgery patients I see have some degree of breast assymetry. In the majority of cases we use the same size implant as the percentage difference becomes smaller as the breasts become larger.

For example: If one breast was 100cc to begin with and the other was 110cc and you placed two 300cc implants. The final size would be 400cc and 410cc. That small of a difference would not be noticed.

The intial 10% difference, becomes only a 2.5% difference after the 300cc implants were placed. If you chose a saline implant, you could potentially add extra fluid to the smaller impant.

But remember, your breasts are sisters, they are not identical twins.

Thank you for your question. Breast asymmetry is very common, particularly size asymmetry. If you are looking to decrease the asymmetry from one breast to another, then you have several options.
1) You can reduce the larger breast with liposuction or a traditional breast reduction technique
2) You can enlarge the smaller one with fat grafting or an implant
3) You can enlarge both but use different size implants
4) A lift procedure may also be needed to help address differences in shape, nipple position and areolar size.
I would visit with a board certified plastic surgeon to discuss your options in more detail.

You can have two different sized implants if you want bigger breasts overall, and the size will be selected to achieve better symmetry in size. Talk to a board certified plastic surgeon for more advice.
