First implants in June 2000..PIPS saline under the muscle. After 3 pregnancies and much breastfeeding …. 2004 replacement… PIPS saline 470cc under the muscle. These implants were so natural looking and feeling. Never had any problems … Decided to explant instead of an exchange. My surgeon, Dr. George Lefkovits, Park Plaza Plastic Surgery, did an excellent job implanting and explanting. His skills in plastic surgery are unsurpassed. His staff is friendly and every member of his team goes out of their way to make your experience comfortable.
