title: [Survivorship of breast implants used in breast reconstruction. 949 implants].
abstract: The authors present from a series of 949 implants their method to calculate the life span of a mammary implant in the framework of breast reconstruction after cancer. In this statistical study, they have calculated the median life span of breast implants (loss of half of staff) by distinguishing it according to each type of implant (content, brand, indication...). The global median life span of a breast implant is 127 months. The median life span of a silicone gel-filled implant is superior than a saline implant because the frequency of deflation of saline implants is more important than the first one, despite that the real rupture percentage of silicone gel-filled implants is under-evaluated by the number of asymptomatic rupture. For saline implants, the median life span is clearly decreased by the initial under-inflation (108 months against 127 months) doubling the secondary deflation risk. In this series, the authors have been able to compare the evolution of implants according to their initial indication (reconstruction or aesthetic) and sometimes at a same patient, they have not observed significant difference of the median life span over a period of five years for an implant used in breast reconstruction after cancer or for an implant used in symmetricalization. In this series, the life span of saline implants is significant different in function of the brand of the implant demonstrating the comparative study usefulness by brands.
