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.
