I appreciate your question. The size of implant best for you is dictated by your chest wall measurements. Once we determine that we can choose the profile based on what you want or need to achieve. If you are seeking a natural look, then the diameter of the implant should be equal to or, more ideally, smaller than the width of your breast. The breast width is a measurement of how wide your breast is at the base, which should be measured at the level of the nipple. Choosing an implant that is smaller in diameter than your breast width will avoid the "side breast" fullness that is often associated with a more artificial appearance. Other than that, you should choose the implant based on volume, not on the dimensions of the implant. You should choose a board certified plastic surgeon that you trust to help guide you in this decision. Anatomic gummy bear implants under the muscle would be good choice for you. These highly-sought-after, anatomic implants offer a look that more closely resembles the natural silhouette of a breast, and, therefore, are a very attractive option for individuals seeking a natural-looking, aesthetic primary breast augmentation. Additionally, these implants are an especially excellent option for patients undergoing restorative or corrective breast surgery because they provide more stability, shape, and reduced incidence of capsular contracture. Compared to other types of silicone gel implants, the silicone in the cohesive gel implant is more cross-linked; therefore, should the implant shell “rupture,” it maintains its shape and silicone does not leak. During your breast augmentation consultation, you should feel the different types of implants available, and try on various implant sizers in front of a mirror to help you to get an idea of how you will look following the surgery. You should also bring pictures of the look you would like to achieve, as well as a favorite top to wear when trying on implant sizers.In my office we also use the VECTRA system. It takes photos of you from different angles to create a 3D image. It leaves you with a 3D image of your breasts you can see from angles you have never seen before. I have found it incredibly useful for my patients when discussing breast augmentation. What I love about the VECTRA is how it helps my patients. It helps YOU see your breasts. Really see your breasts. Photos can be unforgiving, and a 3D photo really shows it like it is. VOLUME: Is one breast larger than the other? This has 2 different ways of looking at volume, which takes into account ribcage and position differences. WIDTH: Is one breast wider? Is your chest ribcage asymmetric? CLEAVAGE: What is the natural spacing between your breasts? Cleavage is an area many of my patient really want to improve and fill when they do an implant. For sure implants help this area, but there are natural differences in the cleavage spacing which we can’t control. Vectra does an analysis of this to show where your natural breast ends. IMF: Our fancy doctor term for the bottom of the breast fold is the inframammary fold. The IMF is where your underwire would go, i.e. where your breast starts from. Turns out our breasts don’t usually start at the exact same place. This difference in position can make the breasts look different and affect nipple position. NIPPLE POSITION: This one tends to be more noticeable. Where are your nipples? Are they even?The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery.Best of luck!
