Abstract:

Background
Before the COVID-19 pandemic, access to otolaryngology and head-and-neck surgery was limited in low- and middle-income countries (LMICs). The pandemic has increased the burden on LMIC health systems by causing unanticipated expenses, delayed care, and changes in research activity. We aimed to assess the landscape of global ENT research during the pandemic.

Materials and methods
The authors developed a search strategy composed of the following keywords: “otolaryngology,” “head and neck surgery,” and “low- and middle-income countries.” Then, they searched eleven citation databases via the Web of Science from January 01, 2020, to May 03, 2021. They imported the result as metadata into VosViewer and ran bibliometric analyses to identify the most influential institutions, countries, and themes.

Results
During the study period, 3077 articles were published. Two hundred eighty-nine articles (9%) mentioned COVID-19 explicitly. The second most common theme was pediatric ENT (223 articles, 7%). The United States had the most publications [1616 articles, 12,033 citations, and 2986 total link strength (TLS)], followed by China (336 articles, 10,981 citations, and 571 TLS). South Africa, the first African country, was fourth (302 articles, 699 citations, and 908 TLS), while Brazil, the first South American country, was seventh (158 articles, 582 citations, and 376 TLS). The most prolific institution was the National Institute of Allergy and Infectious Diseases (186 articles, 1110 citations, and 674 TLS).

Conclusion
COVID-19 was the most common research theme during the pandemic, surpassing pediatric ENT.
