On October 14-15, 2003, the FDA held a public meeting to discuss Inamed’s research on their silicone gel implants. The company is asking the FDA to approve their implants as safe and effective, but the company’s own research shows substantial complication rates and worrisome increases in symptoms for women using their implants. This issue brief is based on the FDA’s analysis of the research by Inamed.
Augmentation Patients
There were 494 augmentation patients enrolled in Inamed’s “core study” of silicone breast implants. Ninety percent of these 494 patients participated in follow-up after two years, and 81% completed follow-up after three years.
Complications after Three Years with Implants

* Baker III or IV capsular contracture is a painful condition where scar tissue around the implant tightens, thus causing the breast to become firm, hard, and distorted.
Symptoms before Implants vs. Two Years after Implants
The augmentation patients in the “core study” were asked about numerous health symptoms both before they were implanted and after two years with silicone gel breast implants. Overall, there were substantial increases in the number of augmentation patients reporting fatigue, pain, joint problems, and other symptoms — in some cases, the numbers tripled from before surgery to two years later.

Reconstruction Patients
Complications after Three Years with Implants
There were 221 breast cancer reconstruction patients enrolled in the “core study” of silicone gel breast implants. Ninety-five percent of these 221 patients participated in follow-up after two years but many had not yet completed three years when the analyses were completed.

Symptoms before Implants vs. Two Years after Implants
The reconstruction patients in the “core study” were asked about numerous health symptoms both before they were implanted, and after two years with silicone gel breast implants. Overall, there were substantial increases in the number of reconstruction patients reporting joint pain, neurological symptoms, hair loss, rashes, and morning stiffness.

Revision Patients
Complications after Three Years with Implants
There were 225 revision patients enrolled in the “core study” of silicone gel breast implants. These women had new breast implants that replaced problem implants, and their complication rate was generally higher than augmentation patients but lower than reconstruction patients. Eighty-seven percent of these 225 patients participated in follow-up after two years, and 83% completed follow-up after three years.

Key Points to Summarize Complications and Symptoms
- The most frequent complication is re-operation, which means that most women getting breast implants will require more than one surgery and additional visits to the doctor.
- Most implants are removed to treat complications. The most frequent reason for re-operation is for capsular contracture, which is the most common complication and can be painful and disfiguring.
- Autoimmune disease signs & symptoms increase over time.

Do Breast Implants Improve Quality of Life?
Inamed also used several measures of health and mental health to evaluate implant patients’ quality of life before and after receiving breast implants. On average, women reported poorer health or mental health after implants compared to before.
- Almost every measure of emotional and physical health, including social relationships and self-esteem, declined after getting breast implants. The only improvements were in self-reported sexual attractiveness.
- Most patients who were studied two years after getting implants reported being satisfied with their silicone breast implants. However, they were more satisfied immediately after getting implants than they were two years later.
