ABSTRACT

Introduction: Capsular contracture is a feared complication following both reconstructive and aesthetic breast surgery. The etiology is uncertain, but bacterial biofilms have been suggested as trigger for chronic peri-implant inflammation, eventually leading to capsular contracture. Methods: Data were extracted from patient records included in a prospective cohort between 2008 and 2010. We compared patients who underwent submuscular breast reconstruction using expander implants and those needing implant removal for capsular contracture after aesthetic submuscular breast augmentation. Results: Of 36 included breast implants from 27 patients, 18 implants were inserted for reconstructive reasons and 18 for aesthetic reasons. The median indwelling time was 3 years for aesthetic implants and 3 months for reconstructive expanders. Overall, sonication cultures were positive in 13 implants (36%). In aesthetic implants, sonication cultures were positive in 28% and sonication cultures were positive in expander implants in 44%. Propionibacterium acnes and coagulasenegative staphylococci were predominant. Conclusion: Sonication cultures were positive in approximately 33% of removed breast implants and were comparable for reconstructive expander and aesthetic implants. These findings support the hypothesis that bacterial biofilms play a role in the pathogenesis of capsular contracture, especially after expander reconstruction, as these implants are at the highest risk of contamination during repeated implant-filling procedures.
