Smoking as a Risk Factor for Forehead Flap Wound Outcomes: An Analysis of 1030 Patients

The forehead flap is a local transposition flap based on a pedicled vessel commonly used to reconstruct facial defects. Often patients requiring reconstructions are smokers, yet the effects of smoking on forehead flaps are not well defined. Our study is aimed to examine smoking as a preoperative risk factor for complications following forehead flaps.

This retrospective cohort study used data collected from the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2019. Multivariate logistic regression models were fitted to evaluate the association between smoking and development of wound complications.

A total of 1030 forehead flaps cases were analyzed and separated into 2 cohorts based on current smoking status: 789 (76.6%) nonsmokers versus 241 (23.4%) smokers. No significant differences in rates of wound complications were found for nonsmokers versus smokers (2.7% vs 4.1%; P = .0807), including when adjusted for comorbidities in a multivariate logistic regression model (adjusted odds ratio, 1.297 [95% confidence interval, 0.55-2.9]; P = .5174).

Smoking has been demonstrated to be a risk factor for plastic surgery procedures. However, in our review of 1030 forehead flaps, smokers did not have worse outcomes compared with nonsmokers. Although it is still advised to recommend smoking cessation given multiple health benefits, smoking status should not preclude candidacy for facial reconstruction with a forehead flap based on complication risk.
