Capsular contracture rate in a low-risk population after primary augmentation mammaplasty.

BACKGROUND

The safety of augmentation mammaplasty has increased dramatically in the past 20 years. Capsular contracture (CC) is the most commonly reported complication of augmentation mammaplasty.

OBJECTIVES

The authors report the incidence of CC in a low-risk patient population after primary augmentation.

METHODS

The authors retrospectively reviewed the charts of 856 consecutive patients who underwent primary augmentation mammaplasty between 1999 and 2009. This series did not include patients who underwent breast augmentation-mastopexy, secondary augmentation, revision, and/or reconstruction. Data points included demographics, functional and aesthetic outcomes, complications, and revision rate/type.

RESULTS

The overall incidence of CC in 856 patients was 2.8%. Average follow-up time was 14.9 months. Antibiotic irrigation decreased CC rates from 3.9% to 0.4% (P = .004). Tobacco users had higher rates of contracture than nonsmokers (5.5% vs 1.9%; P = .036). Saline implants had a higher CC rate than silicone gel (4.3% vs 1.3%; P = .032). Using multivariate logistic regression, CC was 7.89 times more likely in saline implants than in silicone gel (P = .027, 95% confidence interval, 1.26-49.00).

CONCLUSIONS

Based on our findings, it is apparent that the early CC rate in primary augmentation can be less than 1%. To avoid CC, we advocate an inframmamary approach, submuscular implant placement, and antibiotic irrigation of the breast pocket.
