Patients' options in the United States are currently limited to saline fill
ed breast implants for primary augmentation. The amount of fill volume plac
ed into a saline implant directly impacts patient outcome in many ways, inc
luding the aesthetics and palpation characteristics of the breast, risk of
postoperative complications such as visible wrinkling or rippling, risks of
implant shell collapse or folding that impact implant shell life, and the
necessity of reoperations during a patient's lifetime.
