Thanks for your question. I am sorry to hear that you are unhappy with your breast implant size. I believe in doing detailed breast measurements before surgery with all my patients. I always have patients try on implants to get some idea about size and their goals and wishes; however, I believe that the breast tissues and measurements (i.e. width of chest, distance from the nipple to the crease under the breast) really are the most important factors in selecting breast implant size for a good result. Just like fitting a shoe to someone's foot, I believe, a breast implant has to be carefully selected to a patient's tissue dimensions. Saline breast implants can "exceed" natural breast tissue measurements more than silicone gel breast implants in general because they are placed into the pocket "uninflated". Sometimes when "too much" saline is placed into too small of a space, it imparts even more tension on the overlying breast tissues creating a very unnatural and high breast implant that can be very uncomfortable, cause the patient to have a very lengthy recovery from surgery, and even sometimes "stay" too high in a malpositioned location. I believe, the breast tissues dictate "how much space" there is "available" for any breast implant. Exceeding natural tissue measurements increases the chance of the need for revision breast surgery.Sometimes it is not possible to exactly achieve a patient's goals and wishes (in one surgery) based on their anatomy. It sounds like you may have saline breast implants and many times when they are filled to volumes that exceed a patient's tissue measurements, there can be a higher incidence of breast implant malposition and even capsular contraction as well. Typically a bra cup size "equates" to about 200 ccs so there should be a cup size improvement depending on the bra that you are trying on. The implants will often look "high" when they are under the muscle for some time. It can take 3 months or more for the implants to "drop" at times. I usually, recommend bandeau straps and implant-displacement exercises to my patients to facilitate this, but this is something to specifically ask you plastic surgeon about. In general, you can always "go bigger" after 6 months (although I think it's better to wait a full year before considering) re-augmentation. I hope this helps. Good luck!
