The modern breast implant LA could be a two-component prosthetic device manufactured with a virtually impermeable silicone elastomer shell stuffed with a stable filling material, consisting of either saline resolution or silicone gel. This shell and filler implant was originally developed by Cronin and Gerow in 1963 using silicone gel because the filling material contained inside a skinny, swish silicone elastomer shell. Since that point, each silicone gel– and saline-filled implants have undergone many technical alterations and enhancements.
