Although difficult to tell for sure without examining you, you do appear to have a low nipple position and an overhanging breast, and the degree of these factors will determine whether you will achieve a good result from augmentation mammoplasty procedure alone or whether you will require some form of breast lift in order to achieve a satisfactory shape.
Also, since you are not looking for a large augmentation, I am concerned that 400cc implants will make you larger than you desire.
Although not completely accurate, you will still get a good idea of how much that size implant will enlarge your breast mound by trying on sizers in a stretch bra. As to implant profile, this will depend upon the size of implant chosen and what its width is in relation to the width of your breast.
It sounds like you need to discuss your goals further with your surgeon or even obtain a second opinion. (Robert M. Grenley, MD, Seattle Plastic Surgeon)
Getting the “Best Breast”
I understand your concerns, and looked over your photos. I have found that the best way to ensure that I am doing the kind of augmentation my patients want and expect is to do a sizing process in my presence. This can consist of “trying on” an implant or doing the “rice test.” Every patient is different, and as you have indicated every implant has a different result on different people. Be sure you and your PS are on the same page. (John LoMonaco, MD, FACS, Houston Plastic Surgeon)
You seem to be relatively short with a broad chest according to your measurements. You also seem to be a little asymmetrical with your right side larger than the left. Also, you have about a grade II ptosis (or breast droop) which needs to be taken in consideration. I think your choice of implant is a good one being that you are a B+ and desire a C+, a moderate profile implant will get you there. You are following your base width nicely with the implant as well. You will need a slightly different implant on the left (bigger, not just more volume in the same implant) as well as either lowering of the crease vs. a lift procedure to have a good result. These suggestions are all without the benefit of a proper physical exam. (Pablo Prichard, MD, Phoenix Plastic Surgeon)
Augmentation mammoplasty procedure and implant volume
The simplist rough estimate way to see what volume may be right for you is to do a baggy test. Add volume in a loose fitting bra and see. (Steven Wallach, MD, Manhattan Plastic Surgeon)
It is impossible to make a recommendation without an examination. If you have questions, you may want to seek a 2nd opinion prior to surgery. (Robert E. Zaworski, MD, Atlanta Plastic Surgeon)
In general, an increase of less than one cup size (from small C to full C) will require less than 200 cc. 400 cc will likely put you at DD or so. These are just guesses and you should try on sizers in the office. (Kenneth B. Hughes, MD, Los Angeles Plastic Surgeon)
There are no fixed definitions of cup size, and many patients of mine fit into bras of three different cup sizes. Using cup size as a goal is not particularly reliable.
Trying on implants and finding a size that looks good on you will be helpful to your surgeon is picking a size.
400 cc will increase you by about two cup sizes according to estimates by a number of surgeons on this site, who flee that you gain a cup size for each 15 – 250 cc of implant.
Based upon the photos, it appears that you might benefit from a lift, and that implants alone may leave you needing a lift in the near future.
Discuss all with your surgeon. You seem too uncertain to proceed without another discussion. (Jourdan Gottlieb, MD, Seattle Plastic Surgeon)
