This study retrospectively investigates the incidence and risk factors for venous thromboembolism (VTE) in patients undergoing maxillofacial surgery. Data were obtained from patients treated between January 2005 and June 2006. Patients' records were reviewed for complaints and information relating to deep venous thrombosis (DVT) and pulmonary embolism (PE). All patients completed a questionnaire on complaints relating to DVT and PE. The patients were classified according to risk and the incidence of reported DVT and PE was calculated. The study population comprised 411 patients with a mean age of 32 (± 17) years. The median postoperative follow-up period was 53 (23-639) days. None of the patients received thromboembolism prophylaxis. The incidence of VTE in the study group was 0.5%. Logistic regression analysis demonstrated a relationship between body mass index and hospital stay with thromboembolism (p < 0.05). Patients undergoing pre-implant surgery with bone graft proved to be at risk (p = 0.07). The incidence of VTE in oral and maxillofacial surgery seems to be low, but thromboembolism prophylaxis may be justified in patients with clear potential risk factors. © 2009 International Association of Oral and Maxillofacial Surgeons.
