Povidone-iodine combined with antibiotic topical irrigation to reduce capsular contracture in cosmetic breast augmentation: a comparative study.

BACKGROUND: Antibacterial lavage with topical antibiotics may reduce the occurrence of capsular contracture (CC) in breast augmentation.
OBJECTIVES: The authors investigate the efficacy of povidone-iodine combined with antibiotic irrigation in reducing the CC rate.
METHODS: The charts of 330 consecutive women who underwent cosmetic breast augmentation during 2 different periods (group A: 2004-2009, n = 165; group B: 2009-2010, n = 165) were retrospectively reviewed. All patients in the series underwent augmentation with the same surgeon (A.S.) via the inframammary approach and dual-plane pocket. In group A, patients received a single perioperative dose of 1.5 g of intravenous cephalothin and 750 mg of oral cephalexin twice a day for 7 days after discharge. In group B, patients perioperatively received 750 mg of intravenous cefuroxime, and each implant and pocket were irrigated with 25 mL of a 10% povidone-iodine solution mixed with 750 mg of cefuroxime and 80 mg of gentamicin diluted in 15 mL of 0.9% sodium chloride solution. After discharge, patients received 500 mg of oral levofloxacin once a day for 5 days. Postoperative complications included occurrence of infection, hematoma, seroma, and CC.
RESULTS: Mean (SD) postoperative follow-up in groups A and B was 24 (+/- 13) months and 22 (+/- 3) months, respectively. The postoperative superficial wound infection rate was 1.8% and 1.2%, the seroma rate was 1.8% and 1.2%, and the hematoma rate was 0.6% and 1.2% in groups A and B, respectively. Ten CC cases (Baker grade 3 or 4) in group A and 1 in group B were reported (6% vs 0.6%; P = .006).
CONCLUSIONS: Povidone-iodine and antibiotic irrigation in cosmetic breast augmentation yielded a lower CC rate than standard perioperative antibiotics in this series of patients.
