Saline solution2
There are four general types of breast implants, defined by their filler material: saline solution, silicone gel, structured and composite filler. (wikipedia.org)
[5] In surgical practice, after having installed the empty breast implants in the implant pockets, the plastic surgeon would then fill each device with saline solution through a one-way valve and, because the required insertion incisions were short and small, the resultant incision scars would be smaller and shorter than the surgical scars typical of the pre-filled, silicone-gel implant surgical technique. (wikipedia.org)
Implant5
[ clarification needed ] [4] Nonetheless, in the 1990s, the saline breast implant was mandated to be the prosthesis usual for breast augmentation surgery, the result of the U.S. Food and Drug Administration 's (FDA) temporary restriction against the importation of silicone-filled breast implants.
