The fate of breast implants: a critical analysis of complications and outcomes.

Abstract

Complications and outcomes were monitored following the implantation of 1655 breast implants over a 15-year period. Smooth, polyurethane, and textured implants were used in a variety of clinical settings. The time course of capsular contracture was analyzed by the Kaplan-Meier method. Regardless of implant type or indication for surgery, the probability of contracture increased with time. Polyurethane-covered implants were associated with a significant reduction in the risk of contracture for at least 7 years following implantation. Smooth and textured silicone implants had contracture rates similar to each other, and the particular type of surface texturing (Biocel versus Siltex) was of no consequence. Contracture was more common following breast reconstruction and implant replacement than after augmentation mammaplasty and was not affected by filler material or implant size. Implant position did not alter the risk of contracture after augmentation; tissue expansion did not affect the risk of contracture after breast reconstruction. Infections were unusual but most common after reconstruction and unrelated to surface texture or filler material. Skin wrinkling was more frequent with saline implants and in the presence of surface texturing. Implant rupture was rare, with an incidence of 1 per 760 implant-years. Implant-associated connective-tissue disease was noted in only one individual, an incidence of 1 per 3801 implant-years.
