✦ Synopsis

Abstract

Background

We aimed to determine predictors of morbidity in patients undergoing microvascular free flap reconstruction of the head and neck.

Methods

We prospectively evaluated 796 cases between 1999 and 2007 using univariate and multivariate analysis to determine predictors of morbidity and prolonged hospital stay.

Results

Two hundred thirty‐nine patients (30%) developed major complications. Age, body mass index (BMI), American Society of Anesthesiology (ASA) score, Kaplan Feinstein comorbidity index (KFI) score, preoperative hemoglobin, and tracheostomy were independent predictors of major complication. Predictors of prolonged hospital stay included age, recent weight loss, alcohol excess, ASA, KFI, preoperative hemoglobin, mucosal surgery, anesthesia duration, and crystalloid replacement volume.

Conclusion

Several variables are associated with an increased risk of development of major complications following free flap reconstruction of the head and neck. Although many of these variables are irreversible, they aid risk stratification of patients undergoing free flap reconstruction, and assist clinicians in making treatment decisions, consenting, and providing patients with realistic expectations regarding their perioperative course. © 2010 Wiley Periodicals, Inc.
