New breast augmentation. Would I benefit from 450cc implants? (Photo)

I would suggest not going any larger. You already have some bottoming out from the weight of these implants. If you go larger, your tissue is stretched and thinned even more and you will have more sagging. Please do not go larger.

Dear Maryhe1844,
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.

It's possible that "N-SSF520cc" refers to the Natrelle Style 20 High Projection (HP) silicone gel breast implant, which has a maximum fill volume of 520cc. This implant has a full projection, which means that it is designed to create a more rounded and full look to the breasts.

It's important to confirm with your doctor which implant has been chosen for you, as there are many different implant brands, styles, and sizes available. Additionally, you may want to discuss any concerns or questions you have about the procedure with your doctor prior to the surgery.

Best of luck !
