Abstract
The aim of this paper was to evaluate the association between ‘asymptomatic or mildly symptomatic’ severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (AS/MS-COVID) and surgical site infection (SSI) after repair of craniomaxillofacial injury (CMFI). Using a case-control study design with a match ratio of 1:4, we enrolled a cohort of AS/MS-COVID cases with immediately treated CMFI during a one-year period. The main predictor variable was SARS-CoV-2 infection (yes/no), and the outcome of interest was SSI (yes/no). The other variables were demographic, clinical, and operative. Appropriate statistics were computed, and p<0.05 was considered statistically significant. The study group comprised 257 cases (28.8% female; 13.2% aged ≥ 60 years; 10.5% with fractures; 39.7% with involvement of nasal/oral/orbital tissue [viral reservoir organs, VROs]; 81.3% with blunt trauma; 19.1% developed an SSI [vs 6.8% in the control group]) with a mean (SD) age of 39.8 (16.6) years (range 19–87). There was a significant relation between SARS-CoV-2 infection and SSI events (p<0.0001; odds ratio 3.22; 95% confidence interval 2.17 to 4.78). On subgroup analysis, SSIs significantly increased with age ≥ 60 years, presence and treatment of fracture, contact with VROs, and prolonged antibiotic use (PAU). However, multivariate logistic regression analysis confirmed a positive effect only from old age, contact with VROs, and PAU (relative risk = 1.56, 2.52, and 2.03, respectively; r = 0.49; p = 0.0001). There was a significant 2.8-fold increase in SSIs among AS/MS-COVID cases, especially in those aged ≥ 60 years, or those with injuries to VROs, or both, who therefore required PAU.
