“…Hearing loss and tinnitus were the next two most often reported complaints, both of which recovered during the second phase. Our findings corroborated the finding of Hassani et al (23), who reported that the audiovestibular symptoms resolved over time. Therefore, several audiovestibular complications reported during COVID-19 infection may be temporary.…”

Background and ObjectivesConcerns about ototoxic and vestibulotoxic effects have been raised with the use of antiviruses in the treatment of COVID-19. This study aimed to determine the effect of hydroxychloroquine (HCQ) and examine the auditory system and its associated auditory and vestibular symptoms in patients with COVID-19.Study DesignProspective study.PatientsThirty patients with a history of HCQ (HCQ+) and 30 patients without drug use (HCQ−), and 30 healthy adults as the control group participated.Main Outcome Measure(s)Audiological assessments and evaluation of audio-vestibular symptoms. Evaluations were also repeated 1 month later.ResultsBoth HCQ+ and HCQ− groups showed poor pure-tone audiometry (PTA) thresholds and decreased transient evoked otoacoustic emission amplitudes at high frequencies in comparison to the healthy group. Despite the lack of significant differences in PTA between the two groups of patients, the differences in transient evoked otoacoustic emission amplitudes were significant. PTA thresholds and otoacoustic emission showed improvement after 1 month. Dizziness was the most common symptom that was reduced after 1 month.ConclusionSlight hearing loss was seen in patients with COVID-19 with or without HCQ. Also, hearing thresholds in the HCQ+ group did not show a significant difference compared with the HCQ− group. Nevertheless, it seems that more damage is done to the hair cells of patients with HCQ intake than in other patients. Hence, the ototoxicity effect of high doses of HCQ use in the COVID-19 patients should be considered. A relative improvement in the hearing was seen over time in both patient groups.

“…In current study, there was no significant difference between the study and control groups as regards low repetition & high repetition rates ABR parameters (table 6). This finding is consistent with a study conducted by Hassani et al (22) who stated that there was no significant difference between the study and control groups as regards ABR parameters at high and low repetition rates.…”

Background: Coronavirus disease 2019 is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection. The origin of COVID-19 was reported in December 2019 in Wuhan, China, where cases of unknown pneumonia were reported. A novel coronavirus was obtained from these cases and was suggested as the cause of this outbreak. Aim of the Work: To detect presence or absence of auditory dysfunction and its type in COVID-19 patients. To investigate the possible site of lesion (up to the level of brain stem) in relation to COVID-19 infection.Patients and Methods: The present study was conducted on a total of forty-five subjects in

“…Several studies have highlighted the effect of COVID-19 infection on the functioning of the auditory system, but the results so far have not been consistent [2,[4][5][6][7][8][9]. The present study aims to assess the auditory system functioning in individuals post-COVID-19 infection and to compare the results from individuals who have not been infected.…”

“…Its manifestations are changing with time, and infected individuals show a gamut of symptoms ranging from fever, mild to moderate respiratory illness, fatigue, and gastrointestinal complaints[2,16]. Individuals with COVID-19 can have longterm complications, including lung damage, neurological ing function tests[5,9,[17][18][19][20][21][22] while others have shown, in patients who have recovered from mild-to-moderate degrees of infection, no significant difference before and after COVID-19 infection[6][7][8]23]. In 2020 Mustafa reported significantly reduced high-frequency pure-tone thresholds and reduced otoacoustic emission (OAE) amplitude in…”

IntroductionCoronavirus disease (COVID-19), considered to be caused by a novel coronavirus (SARS-CoV-2), is an acute respiratory disease which was declared a pandemic by the World Health Organization. Previously published reports have shown contradictory findings on the involvement of the auditory system in individuals infected with COVID-19. The present study aims to assess auditory system functioning in individuals post-COVID-19 infection and compare the results with individuals without COVID-19 infection.Material and methodsParticipants in this study were 30 individuals who had experienced mild COVID-19 infection and 30 individuals who never had COVID-19. Participants were aged between 18 and 40 years. Testing was done 1 to 6 months after infection, and involved conventional and extended high-frequency audiometry, speech perception in quiet and at different signal-to-noise ratios (SPIN), transient evoked otoacoustic emissions (TEOAEs) in quiet and in the presence of contralateral noise, and auditory brainstem response (ABR) in the ipsilateral and contralateral mode.ResultsNone of the tests – pure-tone thresholds, speech perception in quiet and in noise, TEOAE with and without contralateral noise, and ABR – showed any significant difference between individuals who never had COVID-19 infection and those who had recovered from the infection. Both afferent and efferent auditory pathways showed normal findings in individuals post-COVID-19 infection.ConclusionsIndividuals who have been infected with mild COVID-19 did not show any significant deficit in any of the audiological tests, suggesting that the disease does not cause any permanent harm to the auditory system after the infection has subsided.
