“A frequently occurring symptom following COVID-19 is dizziness. Yet, the causes of post-COVID-19 dizziness are still largely unclear. This paper presents a case of a patient in his 40s who developed persistent dizziness after a SARS-CoV-2 infection. Dizziness only occurred during nasal respiration. Inspection of the tympanic membrane on respiration indicated a patulous eustachian tube (PET). “

“Patients who had been diagnosed with COVID-19 seem to be more likely to suffer from vertigo/dizziness and to compensate more slowly. COVID-19 infection may cause inner ear damage and lead to vestibular dysfunction.”
