ABSTRACT
COVID-19 is a viral infection that mainly affects the lower respiratory tract and with the affinity of the Spike protein to the Angiotensin 2 converter enzyme, inducing a prothrombotic state which may lead to compromising of the cardiovascular, central nervous, auditory, and vestibular systems. Viral infections knowingly affect vestibular and auditory systems. This study aimed to present the auditory and vestibular findings of a woman without otoneurological complaints, before the infection with SARS-CoV-2. This is a longitudinal case report, presenting the evolution of the otoneurological clinical picture accompanied by the results of a battery of tests. The results evidenced a unilateral, permanent, cochlear sensorineural hearing loss through altered otoacoustic emissions albeit with normal tonal thresholds, accompanied by peripheral vestibular hypofunction which worsened with time, without any other factor that could justify these findings. This study shows the importance of the complete protocol of tests performed over time for a better understanding of long-time implications of the SARS-CoV-2 infection.
