Silicone Breast Implants and Risk of Platinum Toxicity
Posted on 03 March 2008 | Category: breast augmentation, breast implants, silicone breast implants
Just when I thought I had reviewed all of the known issues relating to silicone breast implants, from the risk of autoimmune disorders to breast feeding, one appears that I not yet heard of…..the risk of platinum toxicity.
The metal, platinum, is used as a catalyst in the cross-linking reaction of the silicone gel and elastomer in silicone gel breast implants and is present in the finished implant at a parts-per-million level. As such, there is the theoretical risk that residual amounts of platinum may diffuse from the breast implant into the surrounding tissues, posing a potential health risk to patients. Dr. Roger Wixtrom of Virginia, a toxicologist, reviews the platinum issue and its risks in the December 2007 Supplement to Plastic and Reconstructive Surgery. Diffusion studies of current manufactured breast implants indicates that only very minute levels of platinum are released and more than 99% of the original platinum is retained in the implant. Also, the platinum that is present is in its most biocompatible form. (zero valence or oxidation) An FDA report on this issue was released on June 16, 2o06 which states..”Based on the existing literature, the FDA believes that the platinum contained in breast implants is in the zero oxidation state, which would pose the lowest risk, and thus the small amounts of platinum that leak through the shell do not represent a significant risk to women with silicone breast implants.”
Allergic reactions to plastinum are known, but these are to higher valence forms of platinum which are not present in current silicone breast implants. Furthermore, in unpublished studies, over 100 human volunteers have been exposed to repeated applications of the platinum catalyst in patches without any evidence of sensitization. Current evidence would indicate that this potential platinum toxicity concern in breast implants does not represent a significant health risk.
