The science of breast augmentation has changed over the past 2 decades in plastic surgery. The “eyeball” technique of just placing volume to fit a patient for implants is gone. The major implant companies made hundreds of sizes of implants for a reason nowadays, and you as the patient deserve to be sized accordingly. No one is just a 275, 350, 425 anymore.
Nowadays the breast width and skin envelope needs to be accounted for along with patients wishes. When I evaluate a patient I ask them “are you trying to look natural, a liitle more than natural, or the augmentation/fake look” and to me these correlates to a moderate, full, or extra full profile respectively.
