The COVID-19 pandemic led to widespread curtailment of routine clinical services, with health systems prioritizing emergency care. This study evaluated the effect of pandemic-related restrictions on maxillofacial and oral surgery (MFOS) services at Chris Hani Baragwanath Academic Hospital by comparing activity during the 2020 national lockdown period with the equivalent interval one year earlier.
The authors performed a retrospective record review. They compared MFOS patients managed between 26 March and 28 December 2020 (the COVID-19 period) with the same dates in 2019 (pre-COVID). Collected variables included patient diagnoses, type of treatment, and treatment setting. Descriptive statistics summarized diagnoses and procedures, and line graphs illustrated trends over time. Comparative analyses between the two periods used χ2 tests with statistical significance defined as P < 0.05.
The abstract reports the principal outcome measures and statistical tests but does not provide full details about inclusion or exclusion criteria, data cleaning, or whether additional covariates were assessed; those details were not reported in the abstract.
Total consultations declined substantially, from 5,032 in the pre-COVID period to 2,926 during the COVID-19 period, representing a 41.88% decrease (P < 0.0001). Procedures performed under general anesthesia also decreased markedly, from 453 cases in 2019 to 272 in 2020, a 39.96% reduction (P = 0.000448).
Trauma-related diagnoses numerically decreased from 249 cases in 2019 to 154 in 2020; however, this change did not reach statistical significance (P = 0.556). Despite the overall reduction in service volume, trauma remained the most common diagnosis during the COVID-19 period, followed by sepsis and pathology.
Across both periods the highest case counts occurred in the 19–35-year age group. The abstract does not report additional demographic breakdowns (for example, sex distribution, comorbidities, or socioeconomic indicators), nor does it provide granular age-stratified outcome data beyond noting the predominant age group.
The largest declines in MFOS service activity were observed during the most restrictive phases of the national response, described as alert levels 4 and 5. Line graphs were used in the study to illustrate temporal trends, though the abstract does not reproduce those figures or provide weekly counts in the text.
The authors conclude that the COVID-19 pandemic and the national lockdown produced a substantial decline in MFOS consultations and general anesthetic procedures. They suggest a potential public health implication: regulating alcohol sales and distribution may help reduce trauma admissions to MFOS services. This recommendation is presented as an inference from observed service reductions occurring under lockdown conditions; the abstract does not provide direct causal evidence linking alcohol regulation to reductions in trauma within this dataset.
The abstract provides key summary results but omits several methodological and contextual details: specific inclusion/exclusion criteria, methods for categorizing diagnoses, whether outpatient versus inpatient encounters were separately analyzed, longer-term follow-up data, and potential confounders. The extent to which reduced presentations reflect true decreases in injury incidence versus changed health-seeking behavior or access barriers is not described in the abstract. These details were not reported in the abstract.
The authors report no conflicts of interest.
