Experience of sudden sensorineural hearing loss following a mild COVID-19 infection.

A woman in her 30s was referred to an otolaryngologist with an acute onset of aural fullness, noise sensitivity, unilateral sudden onset hearing loss, vertigo and tinnitus. She had a confirmed COVID-19 infection 5 weeks prior. A pure tone audiogram confirmed sensorineural hearing loss. MRI identified an empty sella of the pituitary gland and without an obvious cause for hearing loss. Oral prednisolone and betahistine were prescribed, and her audiovestibular symptoms slowly improved over the subsequent months. The patient continues to experience intermittent tinnitus.
