Objective To investigate the related influencing factors of unplanned reoperation (UR) in patients with oral cancer.Methods A total of 160 oral cancer patients with UR who were hospitalized in the Department of Head and Neck Oncology,West China Hospital of Stomatology,Sichuan University from Janu-ary 1,2018 to December 31,2022 were selected as the study group,and another 160 patients without UR in the same period were selected as the matching group by 1:1 matching.The clinical data of the two groups were compared.The variables that met the requirements were screened.The multivariate logistic stepwise regres-sion model was further used to analyze the influencing factors of UR in oral cancer.Results UR mostly oc-curred within one day after surgery in patients with oral cancer (66.88％),mainly due to flap vascular crisis (48.13％).Compared with the matched group,the hospitalization time of the study group was prolonged,the hospitalization cost was increased,and the differences were statistically significant (P<0.05).Multivariate lo-gistic stepwise regression analysis showed that albumin and neutrophil-lymphocyte-ratio score (ANS,OR=1.693,95％CI:1.207-2.347,P=0.002),difference in hemoglobin levels before and after surgery (OR=1.056,95％CI:1.035-1.077,P<0.001) and free tissue flap repair (OR=4.609,95％CI:2.350-9.036,P<0.001) were the influencing factors for UR in patients with oral cancer.Conclusion UR prolongs the hospi-talization time and increases the hospitalization cost of patients.High ANS,large difference in hemoglobin lev-els before and after surgery,and free tissue flap repair are independent risk factors for UR in patients with oral cancer.
