It seems that BIA-ALCL is associated with the texturing that is used in the surface of certain types of implants. This includes the texturing on Allergan style 410 teardrop shaped implants, and the textured round implants from Allergan. It does not seem to be related to whether an implant is saline or silicone filled. Smooth surface implants do not seem to be linked to BIA-ALCL.
Recently the FDA recommended that Allergan voluntarily recall all unused textured surface implants, and this is widely reported. It does NOT mean a recall of implants already in place, and it does not mean they are recommending removal.
What I Can Do for You
While this letter contains limited information, there is an excellent article at the website of the FDA regarding BIA-ALCL. There are also similar summaries at The American Society for Aesthetic Plastic Surgery and The American Society of Plastic Surgeons
Please be assured of my commitment to you and our long-term relationship.
