Breast Implants Talk

There are several ongoing clinical studies (i.e., investigational device exemption (IDE) applications) of saline and silicone gel-filled breast implants. These studies include those for the more cohesive silicone gel-filled breast implants manufactured by Mentor and Allergan (formerly Inamed), as well as studies conducted by other manufacturers. These devices are still in research and have not been approved for marketing.

In addition, Mentor and Allergan will are conduct studies on patients who get silicone gel-filled breast implants after they are approved.

FDA approved saline-filled breast implants for augmentation in women ages 18 and older. FDA approved silicone gel-filled implants for women ages 22 and older. The age restrictions are different because the risks are different for the two products.  For example, silicone gel-filled implants will require frequent MRI monitoring to detect silent rupture (a rupture that can go undetected by you or your doctor).  There is no risk of silent rupture for saline-filled implants. In addition, the health consequences of a ruptured saline-filled breast implant are different from those of a ruptured silicone gel-filled breast implant.

Mentor and Allergan (formerly Inamed) saline-filled breast implants are approved for: (1) reconstruction (primary reconstruction and revision-reconstruction) in women of any age and (2) augmentation (primary augmentation and revision-augmentation) in women 18 years or older.

Mentor and Allergan silicone gel-filled breast implants are approved for: (1) reconstruction (primary reconstruction and revision-reconstruction) in women of any age and (2) augmentation (primary augmentation and revision-augmentation) in women 22 years or older.

FDA restricts the marketing of breast implants for augmentation to women of a minium age because young women’s breasts continue to develop through their late teens and early 20s and because there is a concern that young women may not be mature enough to make an informed decision about the potential risks. However, there is there is no age restriction on the marketing of these products for reconstruction, so as to allow young women to have access to breast implants to replace breast tissue that has been removed due to cancer or trauma or that has failed to develop properly due to a severe breast abnormality.

As for devices that are not approved for marketing, there are various age criteria and other restrictions for women who receive breast implants as part of a clinical study. Contact one of the companies conducting a study for more information. See the company contact information at http://www.fda.gov/cdrh/breastimplants/addsources.html.

Breast implants are used for:

• primary augmentation (to increase breast size for cosmetic reasons)
• revision-augmentation ( revision surgery to correct or improve the result of an original breast augmentation surgery)
• primary reconstruction (to replace breast tissue that has been removed due to cancer or trauma or that has failed to develop properly due to a severe breast abnormality)
• revision-reconstruction ( revision surgery to correct or improve the result of an original breast reconstruction surgery).

FDA has approved four breast implants for marketing in the U.S.:

• In May 2000, Mentor and Allergan (formerly Inamed) received approval for saline-filled breast implants. These implants were approved for breast augmentation in women 18 years or older and for breast reconstruction in women of any age.

• In November 2006, Allergan and Mentor received approval for their silicone gel-filled breast implants. These implants were approved for breast augmentation in women 22 years or older and for breast reconstruction in women of any age.

All breast implants other than these four approved devices are considered investigational devices, including the more-cohesive (“gummy bear”) implants. For a woman to receive an investigational breast implant in the U.S., she must enroll in a clinical study.

Breast implants are medical devices that are implanted either under breast tissue or under the chest muscle for breast augmentation or reconstruction. There are two major types: saline-filled and silicone gel-filled. Saline-filled breast implants are silicone shells that are either prefilled or filled with saline during surgery, and some of these allow for adjustments of the filler volume after surgery. Silicone gel-filled breast implants are silicone shells prefilled with silicone gel. Breast implants vary in profile, size, and shell surface (smooth or textured).
