Abstract：Objective To investigate the causes and risk factors of unplanned reoperation(UPR)after free flap reconstruction in patients with oral and maxillofacial tumors.Methods The data from patients with oral and maxillofacial tumors who underwent free flap reconstruction in Stomatological Hospital of Air Force Medical University from March 10,2020 to June 14,2022 were retrospectively collected.Logistic regression analysis was used to screen the risk factors for UPR during postoperative hospitalization.Results A total of 528 patients were included,and 59(1 1.17％)had UPR,mainly within 24 h after surgery(62.71％).Neck hematoma(37.29％)and venous crisis(33.90％)were the main causes.Multivariate logistic regression analysis showed that the operation duration of more than 12 h(OR:21.21,95％CI:1.74-507.05,P=0.02)and previous history of head and neck free flap reconstruction(OR:3.51,95％CI:1.03-10.41,P=0.03)were independent risk factors for the occurrence of UPR(P＜0.05).Conclusion Patients with operation duration＞12 h or a previous history of free flap reconstruction in the head and neck have a higher risk of UPR during hospitalization.Close attention should be paid to the situation of patients within 24 h after surgery to prevent the occurrence of neck hematoma and venous crisis.
