FDA approves new silicone gel-filled breast implant

The U.S. Food and Drug Administration approved a silicone gel-filled breast implant March 12 manufactured by Sientra Inc. to be used to increase breast size (augmentation) in women at least 22 years old and to rebuild breast tissue (reconstruction) in women of any age.

As a condition of approval, Sientra is required to conduct post-approval studies that will assess long-term safety and effectiveness outcomes as well as the risks of rare disease outcomes.

Silicone gel-filled breast implants are medical devices implanted under the breast tissue or under the chest muscle for breast augmentation or reconstruction. These implants have a silicone outer shell that is filled with silicone gel. They come in different sizes and have either smooth or textured shells.

Breast reconstruction includes 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. Breast reconstruction also includes revision surgery to correct or improve the result of a primary breast reconstruction surgery.

Breast augmentation includes primary breast augmentation to increase the breast size, as well as revision surgery to correct or improve the result of a primary breast augmentation surgery.

With this approval, there are now three FDA-approved silicone gel-filled breast implants in the U.S. manufactured by Allergan, Mentor and Sientra.

“Data on these and other approved silicone gel-filled breast implants continue to demonstrate a reasonable assurance of safety and effectiveness,” said William Maisel, M.D., M.P.H., deputy director for science in the FDA’s Center for Devices and Radiological Health.

“It’s important to remember that breast implants are not lifetime devices. Women should fully understand risks associated with breast implants before considering augmentation or reconstruction surgery, and recognize that long-term monitoring is essential,” Maisel said.

The FDA based its Sientra approval on three years of clinical data from 1,788 participants. Complications and outcomes reflected those found in previous studies of other breast implants.

Sientra Inc. is based in Santa Barbara, Calif.
