Snoopy Deformity? Revision?
Great question! By looking solely at your pre-operative photos I would have suggested a breast lift (mastopexy) be performed at the time of your breast augmentation. A breast lift surgery aims in bringing your nipple/areola to a higher position on your new breasts. Unfortunately, you are now noticing that your nipple and areola are sitting too low on your breasts making your nipples look irregular. I would suggest following up with your board certified plastic surgeon to discuss options to correct this if you are still unhappy with your results. Good luck!
