Thank you for the question and photos. Round implants are used in 95% of primary breast augmentation surgeries in the United States. Round implants are often used to provide a more augmented look rather than a natural look in patients with sufficient soft tissue coverage. If the breast has a good shape, and has enough padding under the skin for the implant, or if there is concern regarding implant pocket control and implant rotations, round implants are the first choice. I believe your breasts have a breast shape of their own, and tear-drop shaped implants are not needed. A tear-drop shaped or anatomical implant is used in cases where your breasts have very little breast tissue such that an adequate shape is not readily perceivable. It is also used for patients who have tuberous breasts in which the lower pole is constricted. So if you prefer a natural 45:55 upper-pole to lower-pole ratio, then you can opt for a tear-drop shaped ‘gummy bear’ implant. However, it holds the risk of implant rotation which means that within in your breast pocket, it may flip up-side down resulting in more fill distribution in the upper-pole of the breast. All this being said, a round implant with a less cohesive filler can also provide a natural look similar to a tear-drop shaped implant. When the silicone gel is not form-stable (i.e., not viscous) it causes the upper-pole of the implant to collapse inward when inside your body resulting in a fill distribution similar to a tear-drop shaped implant. As such, many of us surgeons just use round implants. Please consult with a board-certified plastic surgeon to get more information about the different choices. Hope this helps!
