- Abstract
Introduction: COVID-19 mainly causes airway disease and can leave associated sequelae, such as cognitive impairment. Long Latency Auditory Evoked Potentials (LLAEP) reflect the neuroelectrical activity of the auditory pathway in the structures that involve functions of discrimination, integration and attention, being able to objectively identify possible alterations in the auditory perception, both in sensory and cognitive aspects. Objectives: To analyze the auditory thresholds and latencies of the components of the Long Latency Auditory Evoked Potentials in adult subjects after COVID-19 infection. Methods: We evaluated 20 individuals, between 30 and 58 years (mean 47 years), of both sexes (6 men, 14 women), after proven Covid-19 infection, without previous hearing complaints. All subjects underwent conventional audiological assessment and LLAEP. Results: In pure tone audiometry, 10 individuals (50%) had normal hearing thresholds bilaterally and 10 individuals (50%) had mild to moderate uni or bilateral sensorineural hearing loss. In the qualitative analysis, latency delays were found in 15 individuals (75%) for the following components: P2 in two individuals in the right ear (10%) and in seven (35%) in the left ear; N2 in 14 individuals (70%) in both the right and left ears; and P300 in an individual in the right ear (5%). Conclusion: 50% of subjects after Covid-19 had mild to moderate sensorineural hearing loss. In LLAEP, 75% of individuals presented latency delay of some component, most of them related to a component considered mixed (N2), elicited by exogenous and endogenous factors, that is, related to sensory and cognitive aspects of auditory perception.
