Methodology: A total of 60 patients were included in this study who had recovered from the primary COVID-19 infection and reported with the complaints of tinnitus, vertigo and hearing loss. Pure tone audiogram was assessed for sensorineural deafness, its severity and frequencies affected. Pearson Chi square test was used to see the relation of symptoms with severity of hearing loss.

Results: There were 42 (70%) males and 18 (30%) female patients with age range from 18-50 years with mean age of 28.4 ± 8.1 years. Tinnitus was the most common complaint (83.3%) followed by hearing loss (28.3%) and vertigo (23.3%) patients. None of the patients with complaint of hearing loss had normal pure tone audiogram in either right or left ear (p=0.000). Patients with all the three complaints had more hearing impairment where majority had moderate or severe hearing loss (p=0.000). All patients with isolated complaint of vertigo (9 patients) had normal audiogram in both ears (p=0.000).

Conclusion: Auditory and vestibular system involvement in reasonably common in COVID-19 patients. Tinnitus is the most frequent symptom and it should be investigated with full audiological investigations.
