Breast Implant Clinical Studies
Breast Implants - What Were the Complication Rates from the A95 Study?
The 3-year and 5-year complication rates are shown from the most common 5-year rate to the least common 5-year rate in the table below. The rates reflect the number of augmentation patients out of 100 who experienced the listed complication at least once within the first 3 and 5 years after implantation. Some complications occurred more than once for some patients. The two most common complications experienced within the first 5 years of implantation were reoperation (26% or 26 patients out of 100) and breast pain (17% or 17 patients out of 100).

Augmentation: What Were the Types of Additional Surgical Procedures Performed?
The following table provides a breakdown of the types of surgical procedures that were performed through 4 and 5 years after implantation. Through 5 years, there were 224 patients who had one or more additional operations after the initial implantation (reoperations), for a total of 293 reoperations. These reoperations involved one or more surgical procedures, for a total of 463 surgical procedures. Examples of multiple procedures during a single reoperation include implant replacement for both breasts or a capsule procedure and mastopexy on the same breast. The most common type of additional surgical procedure through 5 years was implant removal with replacement (34% of the 463 procedures performed).

**Some removals were replaced with a McGhan Medical implant, while others were replaced with a non-McGhan Medical implant.
***Through 4 years, other procedures were laser treatment or chemical peel to correct color change of chest/breast, relaxing incisions, excision of excess skin, nipple related. Through 5 years, other procedures were laser treatment of chemical peel to correct color change of chest/breast area, relaxing incisions, excision of excess skin, revision plication of pocket, nipple related.
Augmentation: What Were the Reasons for Implant Removal?
The following table details the primary reasons for implant removal in the A95 Study over the 5 years. Through 5 years, there were 166 devices removed in 98 patients. Of these 166 devices, 156 were replaced and 10 were not. The most common reason for implant removal through 5 years was patient request for a size or style change (42% of the implants removed).

**Includes 1 implant removal where the reason for removal is unknown Through 5 Years
*** Through 4 years, another reason was too much upper pole fullness. Through 5 years, other reasons were too much upper pole fullness and to be smaller/treat ptosis.
