In performing a breast augmentation, evaluation of the patient including the patient's goals, and the patient's physical presentation are key to achieving a successful result. With this information, proper selection of implant can be made.
It is important for U. the prospective patient to understand what happens to the implant dimensions as the size changes. Simply stated, round implants hold a volume of fluid which is either saline or silicone gel. As the implant gets larger they hold a larger amount of volume. The size that people referred to really is a volume in cc's.
As the volume increases so does the size of the implant. The 2 dimensions that may change in the implant RD projection and the diameter. As the implant increases in size, it does still mainly by increasing the diameter while to a lesser extent the projection. In some instances, between size steps, there is no increase whatsoever in the projection. Therefore it is essential to get a correctly sized implant in terms of the diameter in relationship to the size of the chest.
Therefore, it may be beneficial for you to explore with your surgeon different sized implants (different diameter sizes), to see what size would be best for your chest wall and chest configuration. I hope this helps.
