The Summary of Safety and Effectiveness for each of the FDA-approved saline- and silicone gel filled breast implants details safety information known at the time of FDA approval. As the FDA learns of new safety information, it requires companies to update their product labeling. The most current safety information about saline- and silicone gel-filled breast implants can be found in the labeling.
Saline-filled Breast Implants. Saline-filled breast implants are filled with sterile saline (salt water). They come in both smooth and textured shells and can be round or anatomically (tear-drop) shaped. Saline breast implants are also available in low and high profiles, and in many sizes. A saline-filled breast implant is usually empty before implantation. The doctor moves it into place during your surgery, and then fills it. The saline is administered via a process that ensures the implants remain sterile.
Another option is to consider getting your breast implants at a teaching hospital from a learning resident. You won’t get the delicate skill of an experienced, board-certified surgeon, but teaching hospital residents are “assisted by established, experienced, private attending surgeons,” says Beverly Hills plastic surgeon Dr. Robin T.W. Yuan in a RealSelf Q&A.
