It is just about impossible to discern visually the difference between a 375 cc and 400 cc implant once implanted in the breast. both for patients and for experienced plastic surgeons. In fact, one simply cannot tell what implant size is ever in any given patient just by looking at them. One way for you to answer this question for yourself, however, is to ask which of the following outcomes are you more worried about, being made too big, or not big enough? Based on your own answer to that question, you will have a pretty good idea of which implant might be better for you. That being said, it is best to look at plenty of Before and After galleries, ideally those of your surgeon< and let him or her know what your concept of ideal happens to be. Let those photos guide your surgeon in his or her decision making in surgery to select the implant that most closely gets you the outcome you are hoping to achieve. Nevertheless, without a physical examination it is difficult to respond with accuracy, but as mentioned above, the best way to determine which breast implant size is best for you is by first finding out your specific wishes not only with words or letters as in cup size or “not too big” or “natural”, but also with a visual understanding of what you hope to look like. This can be accomplished either with photographs of patients whose breasts and body type look like you, or ideally with photos of patients not only whose breasts are similar to yours, but are also a similar height, weight, and pre-operative breast size. In our own practice we have provided that unique functionality on our website to accomplish exactly that. Unfortunately the most common reason for a woman to be unhappy after her augmentation is feeling as though she is either too big or not big enough. Thankfully, in our practice this is rarely a problem because implant size selection is what we spend most of our time discussing and determining. I do not place the onus of selecting the breast implant size on my patients since they are coming to me for my advice and expertise, but I do ask my patients to be as specific as possible about their aesthetic goals and I then advise them accordingly. Implants vary in width, projection and volume. This can be very confusing to women, who are used to discussing one number only such as “300 cc’s”. To better understand which implant is best for you, in our consultation room we have two shelves one above the other, each with four implants. The top shelf has all the implants with exactly the same width (12.5 cm), yet the less projecting implant with that width is a 275 cc Moderate or Classic, and the most projecting is a 590 cc Ultra High Profile. On the lower shelf, all of the implants are 300 cc implants, yet the less projecting implant has a width or diameter of 12.8 cm, and the most projecting of the 300 cc implants is the Ultra High Profile which has a 9.7 cm diameter. Once it is determined which implant width or diameter would best fit you, the next step is to decide which what sort of look you are hoping to achieve, i.e. more projection, moderate, or least. This is determined by how much breast tissue you have naturally, and how large you ultimately wish to be. All of this would be discussed during your consultation. And don’t be shy about coming prepared with images which you feel best represent your desired end point. These can be determined by visiting our gallery, or any other photos you wish to bring. The advantage of using our gallery is that all of the relevant information about patient age, implant size and type, are clearly indicated. If you are confident with your selection of plastic surgeon, you should be all set. If you are not sure, I would advise you to seek a second opinion with a board certified plastic surgeon experienced in breast enhancement surgery and make sure that your own sense of aesthetics aligns with that of your plastic surgeon. Your idea of “natural” or “pretty” or “proportionate” might be different from your plastic surgeon’s and it is very important for you to feel confident that you are both of like minds as far as the goals. Best of luck to you and I hope you are successful in achieving the enhancement you are seeking.
