My breast bone has different size. Does this mean we'll have to use two different size implants?

This is an extremely common situation.  During surgery we often use "sizers" which are temporary implants inserted just to help us pick the proper implant size and shape.  These are then removed and replaced with the implant(s) that have been chosen.  Sometimes using different size implants can improve the situation.  However, it is important to remember that breasts are never really symmetrical  before surgery and rarely match perfectly afterwards.  This is not a problem and actually makes the final result look more natural. Make sure you discuss your question with your surgeon before the day of your surgery.  Hope this helps.

But with all implants an improvement in one area may not be an improvement in all areas.  If you are concerned, ask your surgeon, he or she may want to utilize a sizer to determine if in fact different size implants would help.

No one is perfectly symmetrical and if there is an obvious asymmetry, your surgeon would most likely recommend using different sized implants to try to compensate for the difference.  It would be a good idea to go see your surgeon for another exam and to discuss this and prepare for it by ordering sizers and a range of implants for your procedure. ac
