Characterization of Capsule Inflammation in Patients Exposed to Silicone Breast Implants

Sponsor: Centre Hospitalier Universitaire de Besancon

Summary

The use of breast implants, both in cosmetic and restorative surgery, is common. It is a device consisting of a silicone elastomer envelope and the container of which may be silicone gel or saline. They can be texturing carriers (roughness) on the surface of their envelope. If silicone is considered inert and biocompatible, several phenomena should be noted: * Implant placement results in the formation of a periprosthetic capsule which is the product of the inflammatory reaction and will isolate it from adjacent breast tissue * The periprosthetic capsule and adjacent breast tissue are chronically exposed to implant silicone. * Silicone in implants, even intact, has been shown to diffuse through the shell into the periprosthetic compartment and adjacent breast tissue * There is a phenomenon of erosion of the surface of the implants, particularly textured, responsible for the release of silicone particles within the periprosthetic capsule * The rupture of the prosthetic envelope is a dreaded complication, due to the alteration of the aesthetic result and the possibility of leakage of silicone gel * Since 2016, macrotextured implants have been implicated in the occurrence of anaplastic large cell lymphoma associated with breast implants (LAC-AIM) The presence of silicone in contact with tissues seems to promote an inflammatory environment, and this phenomenon seems increased if the implant is textured. Chronic inflammation induced by these devices can therefore have harmful consequences in the long term. INFLAMA study interested in the consequences of the presence of a silicone implant on local inflammatory phenomena within the periprosthetic capsule.
