silicone gel breast implants for cosmetic surgery indications in 2006, there were two puzzling things added to the product labeling.
1. The use of silicone gel implants should be limited to women >22 years olds.
2. That women should undergo routine MRI screening of their implants for rupture every 2-3 years.
The first instruction re. an age restriction on women 18-22 is patently absurd and is a nod to the "unique" political history of silicone breast implants in the USA. One more thing we thank lawyers for!
The second suggestion re. MRI was always puzzling, particularly as the rupture rate is so low for modern implants through the first decade where the FDA would otherwise be having patients undergo 5 screening MRI's (at year 3,5,7, & 9). This intuitively is throwing money down the drain as the yield is low and violates what most people consider appropriate in a screening test.
New data and review of the literature from the University of Michagan suggest that while MRI is fairly accurate in detecting implant-related problems, it is 14 times more likely to detect them in women with implant-related symptoms than in women without symptoms.It has been concluded that because most women in the studies had symptoms, the true accuracy of MRI for detecting implant-related problems in asymptomatic women is probably much,much lower and calls into question the whole idea about routine screening for rupture. Beyond the issue of accuracy, the authors comment that screening tests are generally performed to detect diseases with serious consequences-whereas the health risks associated with ruptured silicone implants, if any, are still unknown. To date, there is no single systemic disease or illness clearly attributable silicone gel implants despite them being the most studied medical device in the history of medicine.
Hopefully this will lead to the updating of the current FDA labeling for these devices that causes some confusion for patients and adds significant extra expense for no benefit.
