Effusion Prevalence at Tympanostomy During COVID-19: Follow-Up

Abstract

Objective: We previously reported pandemic year (2020) intraoperative middle ear effusion (MEE) rate at time of bilateral myringotomy tube (BMT) placement was 18% lower compared to pre-pandemic year (2019). After mandatory stay at home orders (MSHO) and pandemic social distancing precautions were relaxed, we aimed to assess the impact of a persistent pandemic with new COVID-19 variants on MEE presence during BMT. Methods: This study is a retrospective chart summary exempted by Nemours institutional review board at a single tertiary children’s hospital. Children < 18 years who underwent BMT during March 1, 2019–June 31, 2019 (pre-COVID), March 1, 2020–June 31, 2020 (PY1), and March 1, 2021–June 31, 2021 (PY2) were included. Statistical analysis included chi-squared and KruskalWallis. Results: A total of 1069 BMTs were reviewed: 551 (52%) during pre-COVID, 227 (21%) during PY1, and 291 (27%) during PY2. There were no significant differences in age, sex, or BMI across comparison groups. Intraoperative MEE was significantly higher pre-COVID (83%) compared to PY1 (65%) and PY2 (69%) (P
