Polyurethane-coated silicone gel breast implants used for 18 years.

This study aimed to present an update on the use of polyurethane-coated silicone gel breast implants. After 18 years of experience using these implants and 1,257 surgically treated patients, the authors can draw some new conclusions. Their postoperative follow-up evaluation of 300 patients for 5 years, 250 patients for 10 years, and 180 patients for 15 years has shown the lowest incidence of fibrous capsular contraction (1%) with these implants.
