The structured saline-filled implants are most expensive, followed by silicone gel and then saline-filled implants. The differences in cost are not significant, and the additional effort involved in handling a saline implant (smaller incisions, testing and filling the implant) will generally result in total surgery fees comparable to the use of silicone gel implants. The choice of implant should not be based on the relative cost of the implant ($500-$1000 each).
