Hi Meshell,The FDA has not cleared these implants for the U.S. I wouldn't travel to get them, as there are many specific choices available in the states. Sientra only sells to BC plastic surgeons (by ABPS - TheAmerican Board of Plastic Surgery) who are members of ASAPS (TheAmerican Society for Aesthetic Plastic Surgery) and or a member of ASPS (TheAmerican Society of Plastic Surgeons). Recently approved bythe FDA, Sientra (Silimed Corporation) silicone shaped implants are nowavailable for use in the United States. These implants have been usedextensively in Europe and South America for 33 years of safety, quality and patientsatisfaction. They have round implants (with or without texture), and alsoshaped implants which can provide a nice "tear-drop" shape for womenwho want a very natural and "athletic" look. Also, ask if your potential PS has an established, highvolume breast augmentation practice, performing several hundred breast augmentationseach year. Ask to see their before and after photos if you didn’t see any ontheir website. If they are experienced, they should have several 100 breastimplant patients for you to view. I would also recommend that your doctoroffer you the chance to talk to past patients who would be happy to discusstheir experience with you. You need to feel comfortable, so make sure theenvironment is safe as in an accredited surgery center. Also, ask a prospectivesurgeon if he or she has ever published journal articles in professionalpeer-reviewed journals, which they can provide you. All the best, “Dr. Joe”
Pure brand implants are polyurethane implants produced by Sientra, the third company to receive FDA clearance to market their cohesive silicone gel implants (but NOT their polyurethane ones) in the USA.Polyurethane implants have not been used in the US since 1991, when the FDA restricted the use of silicone gel implants, and all but two implant manufacturers (Mentor, and McGhan, now Allergan) went bankrupt or stopped their US sales. This included many lesser-used implants such as polyurethane, Misti-gold, Dual-lumen silicone/saline, etc. But many countries throughout the world still have the availability of polyurethane implants, which did reduce the incidence of capsular contracture (CC), particularly when used above the muscle, as most breast augmentations were done before the early 1990's.When Sientra received FDA clearance for the use of its Silimed line of breast implants in the USA in March, 2012, this approval was not for other implants Sientra produced worldwide since 1978. This includes Pure or any other type of polyurethane implant.The success of polyurethane textured implants minimizing capsular contracture is what led implant manufacturers to develop silicone gel surface texturing in the late 1980's. That, and some bad press about toluene-2,4-diamine (used in the production of toluene diisocyanate, which is used in the production of polyurethane) being a potential carcinogen caused polyurethane to fall out of favor in the US. And, the polyurethane coating seemed to break down after several years, perhaps losing its CC protectiveness. Despite these really ending up being red herrings, polyurethane was never re-studied for FDA re-approval in the US and remains available only outside the US. I hope this helps. You have many alternatives; speak with your ABPS-certified plastic surgeon; he or she really can tell you about the superior implants presently available. Best wishes! Dr. Tholen
The polyurethane coating around silicone breast implants was the issue that caused the FDA such concern in the 1990's and eventually led to a moratorium on all silicone gel breast implant devices. I would definitely recommend choosing an implant that is FDA approved in the United States. There are many great options by Allergan, Mentor, and Sientra.
"Polyurethane Implants" have been in use for many years here in Dominican Republic under the brand name of SIlimed from Brasil (the manufacturer of the SIENTRA implants approved by the FDA). I have a lot of experience with them.I use them in very specific cases where the implant needs to be placed over the pectoral muscle.If the case allows I prefer the Sientra Cohesive Gel Silicone under the muscle, but if needed I use the Polyurethane ones.
Thank you for the question.Although these implants might not be available in California, many of these brands are available in different parts of the world. Dr. Campos
