Implant sizing for augmentation is a big decision for patients. To be pleased with your ultimate outcome, you must be honest with yourself and your plastic surgeon. Good communication is key. 600cc implants are a generous volume but it does appear that your desired outcome requires a generous volume. However, can you get a nice shape, volume, and projection with 500 or even 400cc implants? Sure.Larger implants can be worn well especially in taller patients with wider chest widths. More petite patients with this type of volume tend to look very 'false' and out of proportion with the rest of their body. Going large can also make clothing purchases more difficult. Do you wear a size 6 in fitted dresses now? You will need a new wardrobe and possibly alterations with large implants especially if you want a tailored look. Keep in mind that 600cc silicone implants will add about 2.8 lbs to your breasts which can feel somewhat significant on anyone's frame. If you are very active in a sport, large implants can create difficulty in finding sports bras to serve you and large breasts can begin to feel like a burden. Also, over time, larger implants (larger and heavier breasts) may not age as well as a more modest size due to the stretch on the skin and tissues. I point out these issues to my patients only because I want them to feel good and look good with their implants for many many years and avoid more difficult revision surgeries in the future. 650cc is the largest augmentation implant size that I have used in recent years and I do few in this size range. 700-800cc implants make just about anyone look top heavy and wide (with any profile). I am hoping that surgeons and patients will continue to recognize the issues inherent in going large with augmentation and we will see a continued trend towards more modest augmentation moving forward (as was originally intended with breast augmentation).Best of luck to you and I am hoping you will be thrilled with your result!
