Clinical manifestations and outcomes of otitis media with effusion in adult patients following Omicron infection in China

Abstract

This study investigates the clinical features and therapeutic outcomes of otitis media with effusion (OME) in adults following infection with the Omicron variant of coronavirus disease 2019 (COVID-19), in the context of China ending its "Zero-COVID-19" policy. Conducted as a multicenter, retrospective analysis at two medical institutions in Eastern China from December 2022 to February 2023, the study included patients with confirmed Omicron infection who were diagnosed with OME within two months, adhering to guidelines from the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF). Data on demographics, time from infection to OME manifestation, associated symptoms, and treatment outcomes were collected. Among 68 patients (73 affected ears) with OME post-Omicron infection, common symptoms included cough and nasal obstruction (69.1%). All reported ear fullness, with 86.8% experiencing hearing loss. Tympanic bullae were observed in 72.6% during otoscopy, and most tympanometry results showed a B-type tympanogram (80.0%). An integrated treatment strategy led to an 83.6% cure rate, although 8.2% experienced relapse within 2-3 months. Our findings highlight OME as a prevalent ear complication associated with COVID-19 during the Omicron pandemic, underscoring the necessity for further investigation into its complexities. While the integrated treatment approach proved effective, the 8.2% post-treatment recurrence rate underscores the importance of ongoing monitoring and signals an urgent need for more comprehensive research.

Rising Incidence of Acute Epiglottitis in Eastern China: An Eight-Year Retrospective Study and Its Association with the 24 Solar Terms

“…Additionally, the COVID-19 pandemic, during the study's final years, added complexity by impacting various otolaryngology conditions, including AE, and disrupting healthcare services, which could have influenced our results. 6,28,[31][32][33][34][35][36][37] Furthermore, aside from recognizing environmental factors like temperature and humidity, there is still insufficient knowledge about the underlying mechanisms driving the diverse incidence patterns of AE throughout the 24 STs.…”
