- Abstract
Introduction: Current studies already correlate Covid-19 infection and hearing loss. However, the lack of studies emphasize the importance of further investigation of the auditory pathway in the peripheral and, mainly, central portions. Objectives: Investigate the peripheral and brainstem auditory pathway in verified post-Covid-19 adult individuals. Methods: Approved by the ethics committee, number 50778121.0.0000.0068. Eighteen post-Covid-19 individuals, aged 30 to 58 years, of both genders, with no previous hearing complaints were evaluated. All subjects underwent tonal and vocal audiometry, immitanciometry and brainstem auditory evoked potential. Results: All individuals showed normal immittance measurements. Mild sensorineural hearing loss was identified in five individuals (27.7%) and mild to moderate in five individuals (27.7%). In BAEP, mean values for absolute latencies I, III and V and interpeaks I-III, III-V and I-V were within the normal range. Increased absolute latency values were found for wave III in eight individuals (44.4%), for wave V in four individuals (22.2%), for interpeaks I-III in seven individuals (38.8%) and for interpeak I-V in five individuals (27.7%). Conclusion: In the peripheral audiological evaluation, sensorineural hearing loss was identified in 10 individuals (55.5%), in the central evaluation, some type of brainstem auditory pathway alteration was identified in 12 individuals (66.7%). Therefore, peripheral and central audiological assessment seems to be fundamental in post-Covid-19 individuals. It is believed that studies with a larger population may contribute to a greater understanding of the effects of Covid-19 on the auditory pathway.
