You are absolutely correct in being concerned about the implant volume that has been recommended to you. Look at my breast augmnetation gallery of 100+ women to see what I mean. At 5’1” / 124 lbs and with and A cup breast volume, your natural breast base diameter is probably 11.0 - 11.5 cm. At that base diameter, a volume of 380-410cc by definition means high profile breast implants, which will look completely unnatural on your frame. Or, it could be the recommended implant is a moderate-profile device, but at that volume (380-410cc) the base diameter will be too wide for your breasts (12.5 to 13 cm or more) and you will end up with augmented breasts that appear oddly wide, and visible implant folds and ripples. If your surgeon uses biodimensional planning principles it would be obvious to you, as he or she would have spent several minutes making and recording a number of breast measurements using a tape measure. Biodimensional planning takes into consideration a number of important measurements including base diameter and the change in the length of the lower pole when stretched, and if your surgeon used it they would have most likely arrived at a lower recommended implant volume. Here’s one of the most important things to understand about breast augmentation – maybe THE most important: based on the breast ‘soft tissue envelope’ that you are starting with, and by that I mean the breast skin and subcutaneous breast tissue that will cover and conceal your implants, there is a limited range of implant shapes, dimensions and volumes that will produce 1. A natural-appearing result, which in turn provides you with 2. A very low likelihood of needing a reoperation (or a series of reoperations) for the problems associated with overly large breast implants: visible implant folds and ripples, implant malposition (usually ‘bottoming out’ and/or ‘lateral drift’), lower pole skin stretch deformity, easy implant palpability, stretchmarks and capsular contracture. And yes, I do believe overly large implants have a higher rate of capsular contracture, for any one or all of the following reasons: a possible direct mechanical adverse effect on breast soft tissues; the fact that the bigger the implant is (i.e. the lower the ratio of natural breast volume to implant volume) the more obvious a mild or moderate contracture will be; and what I think is a high probability that surgeons who are willing to place unnaturally large breast implants are, as a group, less likely to be compulsive about using the intra-operative measures and techniques that have been shown to lower the incidence of capsular contracture. If you want a natural-appearing result that is stable in appearance over time, find a surgeon who uses biodimensional planning principles and who recommends a smaller volume, moderate projection implant. Given your body size and the size of your natural breast (A), you are probably a perfect candidate for shaped, form-stable implants. 275 – 300cc is plenty of implant for you, maybe 350 at the most depending on your actual measurements. Don’t obsess about ‘C’ or ‘D’. Just ask the surgeon for the fullest volume breast implant that your natural breast tissue can effectively conceal (and not just for the short term but over time) based on biodimensional planning. You’ll get an outcome that looks full and beautiful but also natural, and that doesn’t cause you problems that lead to frustrating reoperations with a few months or years of your augmentation surgery.
