A 10 Year Experience Using Polyurethane Covered Foam Breast Implants by Dr. Guillermo Vazques, M.D.

Aug 4, 2011 by

As mentioned in some of my other posts, there have been a number of studies, papers and reports written about Polyurethane foam breast implants.

Here is a link to a study on polyurethane foam covered silicone gel breast implants named: A Ten-Year Experience using Polyurethane-Covered Breast Implants by Dr. Guillermo Vazques, M.D. from Argentina.

And the highlights from the paper that jump out at the Furry Brazilian

“In 1978, Zimman et al. [39] published their investigation about the fibrotic capsule around smooth-surfaced breast implants. They undertook a study of the capsule with light and electronic microscopy to observe the formation of collagen and fibroblasts in the presence of the implant.”

That shocked me- does this mean that the fibrotic capsule, which causes capsular contracture, has been studies since prior to 1978 and no solution to preventing capsular contracture has been developed in markets that do not offer polyurethane foam covered silicone gel breast implants?

And this states that since 1992 there have been doctors determining that Polyurethane breast implants were more effective at creating a softer capsule that was less likely to incur capsular contracture:

“In 1992, Barone et al. [3] studied the biomechanism and histopathological effect of polyurethane-coated silicone gel implants and tissue expansion. They concluded that the polyurethane surface was more effective, creating capsules in the implants that were hard at the onset but started to soften in 4 weeks with the edema resolution. Eight months after the procedure, the polyurethane covered implants become softer and less prone to contracture than the textured-surfaced ones”

Of course it seems like the research was very good, but I must jump to the findings of the study involving the 407 patients with 811 breast implants over a 10 year time period (note- this study should have been reporting, the table on page 193 is not complete as it does not detail the time frame being studied…um…seriously important piece of information here! I digress). The findings of the complication rates were shocking:

“The four cases of capsular contracture were two Grade II and two Grade III, according to the Baker Scale.”

Yes, that is correct. Only 4 cases of capsular contracture were reported out of 407 patients that received Polyurethane foam breast implants- a complication rate of under 1% (0.98%).

You can read the FDA reports saying that 20% of women will need to have a re-operation within 8-10 years following a breast augmentation. Yet he is one (of many) studies that shows Polyurethane foam implants do not have the same rate of capsular contracture- the primary reason for re-operation following breast augmentation- as smooth or textured breast implants.

As always, the Furry Brazilian wonders why women are not demanding the FDA review Polyurethane foam breast implants. Why not?
