What to Do when PS Went Bigger Than I Asked with Breast Implants?

It sounds like major miscommunication. I agree with most of my colleagues that now is NOT the time to contemplate any immediate return to the OR. The best course is to wait for a few months and see if you are happy with the results before kicking up sand and revising your breasts.
The following are MY opinions on the topic of WHO CHOOSES the size of the breast implants:- My role is to educate my patients on the plusses and minusses of Breast Augmentation surgery. Every decision has its benefits and shortcomings; Location of incision, location of implant pocket (over/under the muscle), implant shell type (smooth / textured, LP, MP, MP+ or High profile, HP, round vs Anatomical etc), saline VS gel, and finally Implant volume
- The only person carrying these implants will be my patient. Therefore, SHE not me has to have the final word on implant choice. If as a Plastic surgeon I feel that the implants are bigger than what I would have chosen I make her aware of it. If the implants are monstrously too large or rarely too small, I always have the option of declining to operate on that pt. But is is THE PATIENT'S ULTIMATE RIGHT TO DECIDE and choose her implants and no one else's.

I would suggest that you wait at least 3 months. You had enough trust in your doctor that you let him operate on you, now you need to trust his judgment and wait till the swelling is resolved. If you think your breast are too big after the healing period, then you can sit down with your doctor and discuss the replacement.
