Abstract:: The purpose of the current study was to compare two different antithrombotic protocols for free flap reconstruction in head and neck squamous cell carcinoma (HNSCC) patients. Postoperative complications were graded using the Clavien-Dindo (CD) classification and compared between the two groups: the low-molecular-weight heparin (LMWH) group (n = 57) and the unfractionated heparin (UFH) group (n = 59). Patients with HNSCC from January 2010 to January 2022 were included. A total of 116 patients with a mean age of 60.46 years (range 43-83 years) were included in this study. In all, 81 were male (69.8%), and 35 were female (30.2%). Most patients (48.3%) had only grade 1 or 2 complications. CD grades (1-5) were similar between the two groups. Flap loss occurred in 2 patients (1.7%) in the LMWH group (p = 239). Prognostic factors of flap loss were high BMI, hypertension, high T stage, and high N stage. No differences were found between the groups in regard to age, sex, operating times, flap source, recipient vessels and overall complications. The results of this study demonstrate that UFH was as safe and effective as LMWH regarding postoperative complications. Free flap surgery is safe and effective for head and neck reconstruction.
