The cost will of course vary greatly amongst doctors and geographical areas. In my practice, in Massachusetts, saline implants cost about $5400 and silicone implants cost about $7600. This price includes the surgeon's fee, the anesthesiologists fee, the facility fee, and any required follow-up for a year.
An augmentation alone can cost between $5-7000, including implants, surgeons fees, OR and anesthesia.
