“…The researchers also found no difference in extended high-frequency thresholds between groups. 27 The possible reason may be that factors other than Covid-19 that will affect extended high-frequency thresholds become more common with advanced age and the variation in extended high-frequency thresholds increases, or the possible effect of favipiravir use by some of the participants in our study. For this reason, it is recommended that drug users, non-drug users, and control-group studies be examined in a large sample and with an extensive audiological test battery, including extended high-frequency audiometry, to examine a similar effect for favipiravir in a more controlled manner.…”

“…In the literature, no evidence supports that Covid-19 affects the auditory system at the brainstem level in studies conducted with ABR. 8 , 12 , 27 One study reported that mild latency prolongation might be insignificant and may be due to peripheral hearing loss rather than possible brainstem damage. 10 Masking-level difference, a behavioural test that provides information at the lower brainstem level, was also added to the test battery in this study.…”

Objective This study aimed to compare the peripheral-to-central auditory systems of people with coronavirus disease 2019 to a well-matched control group and examine the long-term effects of coronavirus disease 2019 on the auditory system. Method Participants who were outpatients of coronavirus disease 2019 (n = 30) were compared with a well-matched control group (n = 30). Behavioural and electrophysiological tests were performed, and tests were repeated at six months in the coronavirus disease 2019 group. Results Statistically significant differences were observed in the right ear at 10 kHz (p = 0.007) and 12.5 kHz (p = 0.028), and in the left ear at 10 kHz (p = 0.040) and 12.5 kHz (p = 0.040) between groups. The groups had no difference regarding the other audiological test results (p > 0.05). Conclusion Extended high-frequency thresholds were affected in the coronavirus disease 2019 patients. No other findings indicated that the peripheral-to-central auditory system was affected. The effect on extended high-frequency thresholds appeared permanent, but no clinically significant new, late-onset auditory system effects were observed.

Background Many viral infections can cause hearing loss due to affection of cochlear hair cells or neurogenic pathway. Although, the damage secondary to viral infections is mainly cochlear affection; auditory brainstem can be affected as well. It was predicted that SARS-COV-2 infection can similarly affect the auditory system. This study aimed to detect affection in auditory system and if present investigate the possible site of lesion (up to the level of the brain stem) in relation to COVID-19 infection. Methods This is a case control study, where the study group constituted of thirty adults, diagnosed with COVID-19 at least 2 weeks prior to testing and up to 6 months, without previous auditory complaints pre-COVID-19 or other risk factors that could affect the auditory pathway. Fifteen adult participants that were age and gender matched to the study group with no previous history of covid-19 infection constituted the control group. Audiological evaluations done to all participants were pure-tone and speech audiometry, tympanometry, transient-evoked otoacoustic emission with and without contralateral suppression and auditory brainstem response measurements. Results The study group showed significantly worse pure tone thresholds at high frequencies 4 and 8 kHz (p < 0.01), significantly worse transient-evoked otoacoustic emission signal to noise ratio at 2800 Hz and 4000 Hz (p < 0.05) and significantly lower total suppression index (p<0.05). On the other hand, there was no significant difference between both groups in auditory brainstem response wave latencies (p > 0.05). Conclusion COVID-19 had subtle effect on cochlear basal turn, and it is shown that the auditory efferent system may also be affected, while the auditory nerve and afferent brainstem pathways seems to be spared. Moreover, the absence of the symptoms of auditory dysfunction postcovid-19 does not guarantee normal auditory functions.
