Between 1995 and 1998 we implanted 88 Trilucent implants in 48 patients. The experience of 56 explantations in 30 patients are presented in this prospective study. Of 48 patients, 32 returned for review after we wrote to them. Twenty-seven elected to have their implants exchanged immediately for a fourth-generation cohesive silicon implant and three decided to have the implants removed and not replaced. In 14 patients it was clinically obvious that the volume of the implant had changed, although not all patients realized this. The absence of capsular contraction was notable (unanimously Baker II), so that most patients were asymptomatic and had to be convinced of the need for explantation. However, perioperatively, 55% of the implants had thickening or color change caused by the peroxidation of the triglyceride content. Typically the implant capsule was adherent to the surrounding tissues, especially pectoralis major. This prolonged operative time (184 min, on average) and hemostasis was a problem. During the study we developed a standardized operative technique, which enabled us to reduce operative times. Special attention had to be paid to the selection of the new implant volume, because many patients had become accustomed to the increase in the size of their breasts caused by the peroxidation of the implant content. Forty-three percent of patients preoperatively expressed the wish to have even bigger breasts than before. Nearly all of our patients at the three-month postoperative follow-up were happier with the new implants than before. It became apparent that after only two to three years there were obvious oxidative changes in the implants in asymptomatic patients. Based on our study result, the recommendations regarding explantation of Trilucent implants seem justified.
