What Is the Effect of COVID-19-Related Social Distancing on Oral and Maxillofacial Trauma?

PURPOSE: The purpose of this study was to understand the impact of social distancing policies enacted during the COVID-19 pandemic on the epidemiology of oral and maxillofacial fractures at an urban, Level I trauma center in the United States. MATERIALS AND METHODS: The investigators designed a retrospective cohort study and enrolled a sample of 883 subjects who presented for evaluation of oral and maxillofacial fractures (OMF) between March 1 and June 30 in the years 2018 through 2020. The primary predictor variable was the evaluation of OMF during a period with social distancing policies (2020 - experimental group) or without social distancing policies in place (2018 or 2019 - control group). The primary outcome variables were the facial fracture diagnosis, the abbreviated injury scale (AIS), injury severity score (ISS), and the mechanism of injury. Appropriate univariate and bivariate statistics were computed, and the level of significance was set at P < .05 for all tests. RESULTS: The number of subjects presenting with OMF was lower during the period of social distancing (n = 235 in 2020) than during the periods without (2018: n = 330; 2019: n = 318). During the period of social distancing, there were more individuals who presented secondary to assault, whereas fewer individuals presented secondary to falls (P = .05). On average, those who presented in 2020 had more severe oral and maxillofacial injuries (mean AIS = 3.2 ± 1.2 in 2020 vs 3.0 ± 1.1 in 2019 and 3.0 ± 1.1 in 2018. P = .03) and more overall injuries (mean ISS = 20.7 ± 13.1 in 2020 vs 19.2 ± 12.5 in 2019; 17.8 ± 12.8 in 2018. P = .03). CONCLUSIONS: The investigators found that during the period of social distancing through the COVID-19 pandemic, the number of OMF cases decreased but that the severity of oral and maxillofacial and overall injuries was higher.

Odontogenic Infections: Disease Burden During COVID-19 at a Single Institution.

PURPOSE: The purpose of this study was to document the effect of coronavirus disease 2019 (COVID-19) on patients presenting to the University of Washington Oral and Maxillofacial Surgery (UW OMS) with an odontogenic infection. MATERIALS AND METHODS: The investigators designed a retrospective cohort study and enrolled a sample of 889 subjects who presented for an odontogenic infection from March 19 to June 18 in the years 2017, 2018, 2019, and 2020. The primary predictor variable was OMS consultation for an odontogenic infection during a non-COVID-19 (2017, 2018, and 2019) year (control) or during the COVID-19 pandemic in 2020 (experimental). The primary outcome variable was treatment rendered. Appropriate univariate and bivariate statistics were computed, and the level of significance was set at .05 for all tests. RESULTS: There was no significant difference in the incidence of OMS consults in the 2 cohorts (P > .05). The number of patients presenting to the UW emergency department (ED) for an odontogenic infection decreased from an average of 246 in non-COVID years to 151 in 2020. Patients in the experimental cohort were more likely (55 vs 30.0%; P = .04) to present primarily to UW than a dentist and were less likely to undergo an incision and drainage (70.0 vs 88.8%; P = .04), aerosol-generating procedure (70.0 vs 88.8%; P = .04), and incision and drainage in the ED (15.0 vs 41.3%; P = .03). CONCLUSIONS: The investigators did not find evidence of increased hospital or ED burden by odontogenic infections during the COVID-19 pandemic.
