title: Objective Comparison of Commercially Available Breast Implant Devices.
abstract: Breast implants are frequently used for both cosmetic breast augmentation and breast reconstruction after mastectomy. Three companies currently offer FDA-approved breast implants (Allergan, Mentor, and Sientra), but their product offerings-including permanent breast implants, breast tissue expanders, sizers, and post-operative warranty-can be difficult to compare because of brand names and company-specific jargon. The ability to have a brand-agnostic understanding of all available options is important for both the surgical trainee as well as the surgeon in clinical practice. After a brief review of the history of breast implant devices, this review utilizes a unique conceptual framework based on variables such as fill material, shape, relative dimensions, and surface coating to facilitate a better understanding of the similarities and differences between the different company's offerings. Specifically, we identify which types of devices are offered by all three companies, those that are offered by only one company, those that have very limited product offerings, and those combinations that are not available at all. Finally, clinical implications are drawn from this framework that can be used by both cosmetic and reconstructive surgeons to counsel patients about all available options. Importantly, this project is entirely independent of any company's funding, support, or input.
