5'5", 100lbs, A cup to C cup & asymmetry, is it advisable to pick 2 different projections with same ccs? (Photos)

My ability to assess you via the photos (which are good) is still limited by two dimensionality and being still photos, so perhaps I would come to a different conclusion after an in person examination. Having said that, I think that your surgeon's implant selection is off. Although those two implants ( 300 mp, 300 hp) are different by one cm in projection, making up for the lack of projection of your left breast, the 300 hp is also 6 mm narrower, and unfortunately your left breast is also narrower. So, I don't think the result will look as good as anticipated; the wider breast looking even wider and now substantially bigger than the narrower, now bulbous breast. I think that the appropriate set of implants, whichever combo is decided, are likely going to be of different volume, which would make sense because it appears like your breasts have apparently different volume. I do like the concept of using linear measurements (width and projection) as the way to tailor each implant to each breast. I like to start with the limiting side and determine what is the widest, most projecting implant I'd use. Then know the stats on that implant, choose an appropriate implant for the larger breast. Good luck!

Dear KatieSue22,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.
