Influence of COVID-19 pandemic on otitis media with effusion in children: A multicenter, retrospective survey in northern Japan.

OBJECTIVE

The purpose of this study is to compare patient trends in otitis media with effusion (OME) symptoms and diagnoses before and after the COVID-19 pandemic in order to investigate the effects of the coronavirus disease of 2019 (COVID-19).

METHODS

A retrospective, multi-center, observational study was carried out between January 2018 and December 2022 at hospitals in the Iwate Prefecture with full-time doctors. All patients were initially separated into two groups, one for the pre-COVID-19 era (from January 2018 to June 2020), and the other for the COVID-19 era (from July 2020 to December 2022).

RESULTS

In the pre-COVID-19 era, 132 patients had tympanostomy tubes (TT) placed, while 64 patients had them placed in the COVID-19 era. Between the pre-COVID-19 and COVID-19 eras, there were no statistically significant differences in terms of age, sex, side, craniofacial deformity, or adenoidectomy. Children in elementary school showed a greater decline than those in preschool (42-11 patients in elementary school (74%) and 49 to 32 patients in preschool school (35%); p = 0.025).

CONCLUSIONS

The percentage of TT placements for OME dropped to roughly half during the COVID-19 epidemic. This was particularly obvious in elementary school students.
