Breasts will shrink like a pregnant belly if saline is removed. In 1992 we had a panic when women were told they would die from silicone implants resulting from irresponsible journalism by Connie Chung. A number of my patients with long standing implants (>5 yrs.) requested removal. We were amazed that the breasts shrunk back to normal in three days. We them used this discovery to pre-shrink patients like you.
Saline can be painlessly removed by needle in the office. The saline is measured as it comes out and you can get a good idea what size you need for the next operation.
If you look perfect and the size issue is in your head, the surgeon should charge you his regular fees for replacement.
If you look grotesque, then the surgeon would be prudent to do the surgery for free and just charge you the anesthesia and surgery center fee which here in Florida is $1200 for one hour.
If you do not get cooperation, you can post your before and after photos and the surgeons name and let the world decide. That is what RealSelf is about.
