The Effect of Smoking on the Postoperative Course After Head and Neck Reconstruction With a Vascularized Free Flap: A Retrospective Study.

OBJECTIVES

The objective of the present study is to determine the impact of smoking on hospital and intensive care unit stay, need for surgical reintervention, Portsmouth Physiological and Operative Severity Score for the enumeration of Mortality and morbidity, and surgical complications after head and neck reconstructions.

METHODS

All 153 patients who underwent head and neck reconstructions with free tissue transfer at the department of oral and maxillofacial surgery at the University Hospitals of Leuven between January 1, 2015 and December 31, 2018 were enrolled in this retrospective cohort study. Data from medical charts were extracted. Univariate and multiple regression analyses were performed. A level of significance of P < 0.05 (α = 0.05) was used.

RESULTS

Smoking was not associated with Portsmouth Physiological and Operative Severity Score for the enumeration of Mortality and morbidity, hospital or ICU stay, the incidence of postoperative complications in both flap and donor site, or surgical reintervention.

CONCLUSIONS

Regarding the outcomes included in this study, smoking status should not be considered as a critical factor in patient selection for head and neck reconstructions with a vascularized free flap.
