“…In another study, asymptomatic patients with COVID-19 have significantly worsened highfrequency pure tone thresholds and transient evoked otoacoustic emission (TEOAE) amplitudes when compared to control subjects (25). In addition, a recent also study confirmed hearing impairment especially at 1,000 Hz through TEOAE tests (39). Tinnitus is another significant clinical symptom additional to hearing loss, vertigo, and dizziness in patients with COVID-19 infection.…”

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a high transmissible infectious disease that primarily impacts the respiratory system and leads to death as it worsens. Ever since the World Health Organization declared the disease as a global pandemic, the pathophysiology, clinical manifestations, and disease prognosis has been discussed in various literature. In addition to impaired respiratory health, the symptoms also indicated the involvement of the cardiovascular and neurological system after SARS-CoV-2 infection. Despite the pulmonary, cardiovascular, and neurological complications, many reports also revealed the prevalence of vestibulocochlear symptoms like dizziness, vertigo, vestibular neuritis, sudden sensorineural hearing loss, and tinnitus. Though many clinical reports and scientific reviews reported the vestibular and cochlear impairments associated with coronavirus disease 2019 (COVID-19) infection, the underlying pathological mechanisms are still unclear and unexplored. In this review, we discussed the published clinical reports, research articles, and literature reviews related to vestibulocochlear manifestations following SARS-CoV-2 infections. We also summarized the current knowledge about the prevalence, epidemiological and clinical features, and potential pathological mechanisms related to vestibular and cochlear manifestations resulting from COVID-19 infections.

“… 17 On the other hand, other authors noticed significant differences only for the 1000 Hz frequency in patients after the COVID-19 group, compared to the control group. 23 Mustafa et al 17 showed a significant worsening of TEAOAE in patients with asymptomatic COVID-19. In the discussed study, the patients also had an asymptomatic course of COVID-19, which indicates a high risk of neurotrophic complications after the infection.…”

Introduction The symptoms of COVID-19 are primarily respiratory system disorders. Sensorineural hearing loss can be caused by COVID-19, as other symptoms in the nervous system. Hearing loss may also be the only symptom or complication of this disease or the symptoms of long COVID-19. The study aimed to assess hearing in patients after COVID-19 infection. Material and Methods The study conducted ENT and full hearing assessment in COVID-19 infection. All patients underwent complete audiological diagnostics, including threshold tonal audiometry, tympanometry, otoacoustic emissions, and auditory brainstem evoked potentials (ABR) tests. The study group included 58 patients aged 23 to 75 years who were diagnosed with COVID-19 infection six months before inclusion in the present study and reported post-COVID-19 hearing impairment. Results There were statistically significant differences between the control and study groups. Sensorineural hearing loss was found in 65.5% of the tonal audiometry test. The stapes reflex was absent in almost 20% of post-COVID-19 patients. The analysis of ABRs demonstrated longer latencies of wave III, V, and time intervals I–III, I–V in post-COVID-19 patients. Conclusion COVID-19 can damage the inner ear as well as the auditory pathway. Hearing loss may be the only symptom of COVID-19 or be a late complication of the disease due to postinfectious inflammation of the nerve tissue as a symptom of long COVID-19. Prolonged conduction of the auditory pathway shows the affinity of the virus to the nervous system as a symptom of long COVID. It is advisable to perform hearing diagnostics in patients after COVID-19 and provide them with specialist care.

“…There are studies that give contradictory results on this subject [2] , [3] . In the beginning of the pandemic, that was the intense stress atmosphere of that period, it was thought that the symptom of sudden hearing loss could be a symptom of COVID-19 and it has been suggested that sudden hearing loss may be the only symptom of SARS-CoV-2 infection [2] .…”

“…However, different results were obtained in more planned and organized studies carried out in the following time. In one of these studies [3] , patients who had audiological evaluations made just before the pandemic process and whose hearing results were normal, were evaluated during and after the COVID-19 infection, and a significant decrease in hearing level was found only at 1000 Hz.…”
