More than 3,000 participants from three large, multi-center, US clinical studies of silicone implants (Allergan, Santa Barbara, CA) were asked to rate their motivations for breast augmentation surgery prior to implantation. A 5-point scale was used to rate the level of importance, ranging from "not at all important" to "extremely important." Prior to implantation and 1 year after implant surgery, women also rated their level of satisfaction with various aspects of their breasts. This article reviews the data collection methods and current results of these studies, identifying the patient's motivation for breast augmentation surgery and reported post-operative satisfaction.
