This is a question I always get asked and for the most part I don’t think it matters.  There was a study done comparing round implants versus anatomical implants on several breast augmentation patients.  Several received mammogram’s either 3 or 6 months post op and guess what?  They were all round.  A recent study out of New York took 75 patients and in one breast they used a round implant and in the other they used a similar sized anatomical implant.  After having lay reviewers and plastic surgeons  view the before and after photo’s there was essentially no difference.
