Both saline and silicone breast implants are FDA-approved, and therefore considered safe to use. However, there are differences between the two types.
Saline-filled implants are filled with a saline solution. They may be prefilled to a predetermined size, or at the time of surgery for modifications in implant size. If your saline implant were to deflate, the saline simply absorbs into your body, causing no harm.
Silicone-filled implants are filled with silicone gel. All silicone implants are pre-filled before surgery, but are available in a variety of shapes and sizes. A longer incision may be required for these implants to be placed. If your silicone implant were to rupture, it is important to contact your doctor, as the silicone cannot be absorbed into the body. These implants are known to feel the closest to natural breast tissue.
Which implant is used is often dependent on each patient’s individual goals and preferences, though both implants can create a beautiful breast contour.
