Polyurethane Breast Implants- One Manufacturers’ Product Information

Aug 29, 2011 by

NOTE- I do not work for the manufacturer detailed in this post, have never been paid by them; I am not promoting their company, but providing information about Polyurethane breast implants.

Okay- here is some information directly from a manufacturer’s website regarding polyurethane foam covered silicone gel breast implants. You can download the PDF with this information by clicking here. 

The name of this company is Polytech, they are based in Germany. I am not sure if Europeans call Polyurethane foam implants Furry Brazilians or Super Furry Brazilians, but I do know that Polyurethane implants are widely approved and used in Europe.

Some of the highlights and information from their report:

Microthane® Micropolyurethane-Foam Surface

One of the principle considerations for any elective operations, e. g. breast reconstruction or augmentation is to minimize the number of complications. The most common complication of breast-implant surgery is capsular contracture. Implants coated with Microthane® (micropolyurethane foam) have been developed to minimize the capsular contracture rate. In extensive clinical studies over the past twenty years reviewing large numbers of patients, the capsular contracture rates (Baker classification III–IV) have been determined.

The capsular contracture rate for Microthane®-coated implants in virgin tissue is 0–9 % compared to 9–50 % for other implants. In most of the large studies, the capsular contracture rate for Microthane®-coated implants is as low as 03 %1). An extensive long-term study carried out in the United States using the Kaplan-Meier survival analysis confirms the significant reduction of the risk for capsular contracture with Microthane®-coated implants for up to 10 years after implantation. The statistics show that after 8 years the capsular contracture rate with Microthane®-coated implants compared to textured implants is 15 % lower. It is even 30 % lower compared to smooth implants 2).

The low capsular contracture rate is attributed to the ingrowth and microencapsulation of the fibroblasts in the polyurethane-foam matrix (fig. 2). Due to the active healing process, a linear capsular contracture (fig. 1) and the resulting disfigurement of the implant are drastically reduced. In contrast to smooth and textured implants around which a single large capsule is created, the Microthane®-coated implants – due to microencapsulation of the polyurethane foam – encourage the growth of numerous microcapsules around the foam, whereby contractile forces are neutralized.

In 1995, the American health authority “Food and Drug Administration” announced that the estimated excess cancer risk due to micropolyurethane-foam coated implants is less than one in one million over a woman’s lifetime 4). This figure indicates that there existsno significant danger according to standard risk analysis 5). The general risk to suffer from breast cancer is, according to the WHO statistics, one in nine.

Please read the full PDF from Polytech  to assist you with understanding more about Polyurethane implants.

The primary points that always jump out at me regarding polyurethane foam covered silicone gel breast implants are:

  1. Low capsular contracture rate and low rate of reoperation associated with Polyurethane implants
  2. Safety- the ruling by the FDA that Polyurethane foam implants are safe with a cancer risk of only 1 in 1,000,000
  3. Usage- Polyurethane breast implants are used everyday! If they were not safe or effective they would not be used, or gaining and growing in marketshare in key nations such as England and Australia.
Again, I am not promoting this company’s implants, I am promoting awareness about capsular contracture, reoperation and the role of the implant surface in reducing both capsular contracture and reoperation.
