Thank you for the question. These days there are a variety of breast implants available; the variety of breast implant available raise a lot of questions from women considering breast augmentation surgery. Personally, I think that for most patients considering breast augmentation surgery, careful selection of plastic surgeon and careful communication of goals, far outweigh the specific type of breast implant utilized (when it comes to the success of the breast augmentation procedure). Classically, the "gummy bear" breast implants refer to shaped or anatomical breast implants; these implants were designed to better simulate the natural breast shape. The problem with these implants is that if they shift or rotate, the entire breast will change shape as well. This change in breast shape may require further surgery to correct. Round implants, on the other the hand, can shift or rotate without changing the shape of the breasts.I personally prefer the use of smooth and round implants for most patients. Round breast implants also come in a variety of different profiles. The difference between these implants have to do with the dimensions (diameter and height) of the implants. For example, the high-profile implant has a greater projection and a smaller diameter compared to the moderate profile implant. The moderate plus profile implant as projection and diameter characteristics that fall between the moderate profile and high profile implants. I prefer to have a wide selection of implants ( all profiles) available in the operating room. I use intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison. I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. I hope this helps.
