Aim: Reduction mammaplasty is a commonly performed procedure for the treatment of symptomatic macromastia and is increasingly desired by the obese population. With the increasing prevalence obesity in the population, it is imperative to understand its effect on postoperative outcomes. The purpose of this study is to evaluate obesity as an independent risk factor for postoperative complications in breast reduction surgery using 1:1 patient matching through propensity scores between obese patients and non-obese controls.Methods: Between 2005 and 2013, the National Surgical Quality Improvement Program dataset identified a total of 6,016 patients as having undergone primary reduction mammaplasty with 30-day postoperative follow-up. Patients were divided into obese [body mass index (BMI) of 30 or more] vs. not obese (BMI below 30). Patients were initially analyzed using standard multivariable analysis. Using propensity scores obtained from a logistic regression model, patients were subsequently matched 1:1 according to preoperative and operative variables to truly isolate the effect of obesity on surgical outcomes. Outcomes were compared between the matched cohorts using McNemar’s test and the Wilcoxon signed rank test.Results: In unmatched multivariable analysis, rates of overall complications (7.2%vs. 5.3%,P = 0.0024), wound complications (5.5%vs. 3.6%,P = 0.0004), superficial surgical site infection (4.1%vs. 2.8%,P = 0.0050), and wound dehiscence (0.3%vs. 1.1%,P = 0.0005) were found to be statistically different between obesevs. non-obese, respectively. However, when comparing 1:1 matched obese and non-obese patients, only wound complications (4.6%vs. 3.1%,P = 0.0334) were significantly increased in the obese cohort.Conclusion: Using the most robust statistical tools available, obesity was
determined to affect wound complications after breast reduction without increased detriment on other major complications when compared to the non-obese. Obesity should be a considered with other preoperative comorbidities, rather than an independent contraindication to surgery. Breast reduction appears to be safe in the obese patient who is otherwise healthy.
