[Pediatric sensorineural hearing loss related COVID-19. Clinical cases].

Unlabelled: COVID-19 is an acute respiratory coronavirus infection in 2019 caused by the SARS-CoV-2 virus. Currently, the number of neurological complications in the acute or delayed period of coronavirus disease is increasing, including peripheral disorders of the auditory analyzer.

Objective: To present clinical cases of sensorineural hearing loss in children under 5 years of age after a novel coronavirus infection.

Material And Methods: We report 3 cases of unilateral and 1 case of bilateral acquired deep sensorineural hearing loss, while the association with SARS-CoV-2 has been confirmed anamnetically and/or laboratory.

Results: The SARS-CoV-2 virus can have a depressing effect on the cochlea on its own or enhance the toxic effect of viruses during the recovery period after COVID-19. The true frequency of acute sensorineural hearing loss of infectious origin in childhood and, as its outcome, the formation of persistent hearing impairment has not been determined.

Conclusion: Viruses are volatile, contagious, and clinically dangerous due to their complications. Vaccination is the most effective measure for the prevention of infectious diseases.
