Multiple Choice

Which type of implants is no longer allowed in the USA?

Safety and regulation drive this answer. Liquid silicone injected into tissues for cosmetic augmentation was found to cause serious problems—silicone can migrate, trigger granulomas and chronic inflammation, lead infections, pain, and deformities, and it’s hard to remove once placed. Because of these risks, the FDA prohibited cosmetic use of injectable silicone in the United States years ago. In contrast, saline-filled implants and silicone gel–filled implants are manufactured medical devices that have undergone regulatory review and are still permitted under proper medical care. The idea behind the no-longer-allowed option is that injections of silicone are not an approved, safe implant method, whereas the other choices refer to regulated implant devices.
