Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery 2023 FebMicrovascular free tissue transfer is an important reconstructive option for defects of the head and neck. The present study aims to identify preoperative patient- and tumor-specific characteristics, laboratory values, and other risk factors associated with early free flap failure. Retrospective cohort study of 1070 patients. Head and neck surgical oncology service at a tertiary care center from 2005 to 2019. Demographics, comorbidities, preoperative laboratory values, treatment history, and cancer stage were collected for consecutive patients who underwent free flap reconstruction of the head and neck and experienced early free flap failure (<8 days from surgery). In 1070 patients, the prevalence of early free flap failure was 3.8% (n = 41). Female sex (odds ratio [OR], 2.58; 95% CI, 1.36-4.99), presence of peripheral vascular disease (OR, 2.78; 95% CI, 1.05-6.57), and elevated preoperative platelet count (OR, 2.67; 95% CI, 1.20-5.47) were independently associated with risk of early free flap failure. Female sex, peripheral vascular disease, and preoperative thrombocytosis are all strong predictors of early free flap failure. This suggests that hypercoagulability and poor vessel quality may predispose patients to flap loss. Patients with elevated platelets or peripheral vascular disease warrant careful reconstructive decision making and close monitoring in the perioperative period. © 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.
