Single Institute Audit of Maxillofacial Trauma Cases Before and During COVID-19 Pandemic.

Study design: In the year 2020, we saw the emergence of severe acute respiratory syndrome coronavirus 2 causing COVID-19 into a full blown pandemic. This resulted in constraints on healthcare resources, and the attention was shifted to reduce cross contamination and prevent spreader events. Maxillofacial trauma care was also affected similarly, and most of the cases were managed by closed reduction whenever possible. A retrospective study was conducted to document our experience in treating maxillofacial trauma cases before and after nationwide lockdown due to COVID-19 pandemic in India.

Objective: The objective of the study was to compare the effect of pandemic in reported pattern of mandibular trauma and the result of closed reduction procedures in the management of single or multiple fractures in mandible during this time period.

Methods: The study was conducted in the Department of Oral and Maxillofacial Surgery, Maulana Azad institute of Dental Sciences, Delhi, for a period of 20 months, that is, 10 months before and after nationwide lock down which was effective from 23rd March 2020 due to COVID-19 pandemic. The cases were grouped into Group A (those reporting from 1st June 2019 to 31st March 2020) and Group B (those reporting from 1st April 2020 to 31st January 2021). Primary objectives were assessed and compared according to etiology, gender, location of the mandibular fractures, and treatment provided. Quality of life (QoL) associated with the treatment outcome by closed reduction was assessed after 2 months as a secondary objective using General Oral Health Assessment Index (GOHAI) in Group B.

Results: A total of 798 patients sought treatment for mandibular fractures and included 476 patients in Group A and 322 in Group B. The groups showed similar age and male: female ratio. Cases showed a steep fall during first wave of pandemic, and most of the cases occurred as result of RTA followed by fall and assault. The fractures due to fall and assault showed an obvious rise during the lockdown period. There were 718 (89.97%) patients having exclusive mandibular fractures and 80 (10.03%) patients having involvement of both mandible and maxilla. Single fractures of mandible constituted 110 (23.11%) and 58 (18.01%) in Group A and B, respectively. 324 patients (68.07%) and 226 patients (70.19%) had multiple fractures involving mandible in respective groups. Parasymphysis of mandible was most commonly involved (24.31%) followed closely by unilateral condyle (23.48%) then Angle and Ramus of mandible (20.71%) with coronoid being the least fractured. During the initial 6 months after lockdown, all the cases were treated successfully using closed reduction. GOHAI QoL assessment conducted in cases having exclusive mandibular fracture (210 Multiple, 48 Single) showed favorable results with significant (P < .05) difference between the single and multiple fractures.

Conclusions: After one and half years and recovering from the second wave of pandemic that hit the country, we have come to understand COVID-19 better and embraced better management protocol. The study reveals that IMF remains the gold standard for the management of most of the facial fractures in pandemic situations. It was evident from the QoL data that most of the patients were able to carry out their day-to-day functions adequately. As the country prepares for a third wave of pandemic, management of maxillofacial trauma by closed reduction will remain the norm for most unless indicated otherwise.
