Capsular contracture is a risk for anyone who has breast augmentation or reconstruction with implants. It unfortunately occurs more frequently than we would like it to. It can occur early or late after surgery, with saline or silicone implants, in subpectoral or subglandular placement, and in one breast or both. Capsular contracture is probably caused by some excessive scarring; the etiology of the scarring may be unknown, but subclinical infection and long-term failed silicone gel implants probably lead to capsular contracture as well. There is no specific way to prevent it, but measures taken during surgery to reduce scarring and infection may help. Capsular contracture is graded using the Baker classification: I (normal breast) thru IV (severe contracture). Grades III and IV usually require surgical correction.
Allergan’s Core Study followed 455 women following their primary silicone gel-filled breast augmentation. At 7 years post-op (follow-up 74%) the incidence for capsular contracture (Baker III/IV) was 15.5%. At 10 years post-op (follow-up 59%) the incidence for capsular contracture (Baker III/IV) was 19.1%.
The Allergan Core Study also enrolled 147 revision-augmentation patients. At 7 years post-op (follow-up 72%) the incidence for capsular contracture (Baker III/IV) was 20.4%. At 10 years post-op (follow-up 50%) the incidence for capsular contracture (Baker III/IV) was 27.5%.
Mentor’s Core Study followed 552 women following their primary silicone gel-filled breast augmentation. At 3 years post-op (follow-up 67%) the incidence for capsular contracture (Baker III/IV) was 8.1%. At 8 years post-op (follow-up 52%) the incidence for capsular contracture (Baker III/IV) was 10.9%.
The Mentor Core Study also enrolled 145 revision-augmentation patients. At 3 years post-op (follow-up 79%) the incidence for capsular contracture (Baker III/IV) was 18.9%. At 8 years post-op (follow-up 53%) the incidence for capsular contracture (Baker III/IV) was 24.1%.
The reason Allergan has 10 year data and Mentor does not is because Allergan began enrolling patients about one and one-half years earlier.
As you can see, the risk of capsular contracture is higher in revision-augmentation patients. If you ask many surgeons (me included) what the incidence of capsular contracture is in their practice they would probably state numbers much lower than this. Our (speaking for the collective group of surgeons) top of mind recollection of complications and re-operations is not always very accurate…but the numbers, are the numbers. Unless a surgeon has specifically studied the details of his or her practice, and has good patient follow-up, the Core study numbers are the ones that should be used when speaking with patients.
So the bottom line is that your capsular contracture is not unlike others, and can be improved/corrected with surgery. A thoughtful approach to capsular contracture may be helpful in reducing recurrence yet again, but there are no guarantees.
