The Effect of Smoking in the Cosmetic Surgery Population: Analysis of 129,007 Patients.

BACKGROUND

Smoking has been associated with several postoperative adverse outcomes across multiple surgical disciplines, but the literature is limited for aesthetic surgical procedures.

OBJECTIVES

To compare complication rates between smokers and nonsmokers undergoing common cosmetic procedures, identify specific cosmetic procedures where smoking increases the risk of complications, and evaluate smoking as an independent risk factor for major complications following aesthetic surgery.

METHODS

A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Smoking was evaluated as a risk factor for major complications requiring emergency room visit, hospital admission, or reoperation within 30 days after surgery. Multivariate regression analysis was performed controlling for the effects of age, gender, body mass index, type of surgical facility, type of procedure, and combined procedures.

RESULTS

Of the 129,007 patients, 10,621 (8.2%) were smokers. All procedures examined, except breast augmentation, were more frequently performed in the nonsmoker cohort. Overall major complications were similar between smokers and nonsmokers (2.0% vs 1.9%, P = 0.57). In univariate analysis, surgical site infections (0.6% vs 0.5%, P = 0.04) were significantly higher among smokers, but suspected venous thromboembolism (0.2% vs 0.1%, P = 0.01) was significantly higher among nonsmokers. Notably, smokers had a higher risk of major complications after body procedures (2.9% vs 1.0%, P = 0.01), as well as thigh lifts (23.8% vs 3.6%, P < 0.01) and male breast surgery (3.7% vs 1.4%, P = 0.03). In multivariate analysis, smoking was found to be an independent predictor of surgical site infections (relative risk 1.61, P < 0.01).

CONCLUSIONS

Smoking is an independent risk factor of major surgical site infections following aesthetic surgery. Body procedures, as well as thigh lifts and male breast surgery, have higher complication rates in smokers.
