A history of otologic conditions, such as dizziness or vestibular issues, increases the risk of worsened symptoms after COVID-19 infection. This highlights the need for targeted screening in at-risk individuals.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Epidemiology
Background:
- Increasing reports link COVID-19 infection to otologic conditions.
- Previous otologic conditions may heighten susceptibility to post-COVID-19 symptoms.
Purpose of the Study:
- To investigate the association between a history of otologic conditions and the risk of similar or exacerbated symptoms following COVID-19 infection.
Main Methods:
- Surveys administered to COVID-19 positive patients (PCR confirmed, Jan 2020-Sep 2022).
- Comparison of otologic symptom incidence within 10 days post-infection between those with and without pre-existing otologic conditions.
Main Results:
- Of 1,499 participants, 48% had pre-existing otologic conditions (hearing loss, dizziness most common).
- 35.5% with pre-existing conditions reported symptom worsening post-COVID-19.
- Pre-existing dizziness, vestibular neuritis, and vestibular migraine increased odds of related post-COVID-19 symptoms. Younger age and female gender were associated with higher odds for various otologic symptoms.
Conclusions:
- Certain pre-existing otologic conditions are linked to a higher likelihood of exacerbation after COVID-19.
- Findings can inform screening protocols for identifying individuals at greatest risk of post-COVID-19 otologic complications.
