Objective To identify risk factors associated with surgical site infection (SSI) after major oral oncological surgery. Methods This retrospective study reviewed data from patients that underwent major surgery for oral cancer at a tertiary referral hospital in China between January 2005 and July 2016. SSI was diagnosed within 30 days. Demographic, cancer-related, preoperative, perioperative and postoperative data were analysed using descriptive statistics and univariate and multivariate analyses of the risk factors for SSI. Results A total of 786 patients were enrolled, of whom 125 had SSI (15.9%), which were all incisional. Independent risk factors for SSI, identified by multivariate analysis, were diabetes mellitus (odds ratio [OR] 2.147, 95% confidence interval [CI] 1.240, 3.642), prior radiotherapy (OR 4.595, 95% CI 1.293, 17.317) and oral-neck communication (OR 2.838, 95% CI 1.263, 7.604); and factors reflecting large extent resections were tracheostomy (OR 2.235, 95% CI 1.435, 3.525), anterolateral thigh flap (OR 1.971, 95% CI 1.103, 3.448) and latissimus dorsi flap (OR 4.178, 95% CI 1.325, 13.189). Conclusions Multiple risk factors were associated with SSI after major oral oncological surgery. To minimize SSI risk, surgeons managing oral cancer patients should have a better understanding of the risk factors, including diabetes mellitus, prior radiotherapy, tracheostomy, oral-neck communication and flap reconstruction.
