    Abstract:

    Objectives:
    Extensive studies indicate that severe acute respiratory syndrome coronavirus (SARS-CoV-2) involves human sensory systems. A lack of discussion, however, exists given the auditory–vestibular system involvement in CoV disease 2019 (COVID-19). The present systematic review and meta-analysis were performed to determine the event rate (ER) of hearing loss, tinnitus, and dizziness caused by SARS-CoV-2.

    Methods:
    Databases (PubMed, ScienceDirect, Wiley) and World Health Organization updates were searched using combined keywords: ‘COVID-19,’ ‘SARS-CoV-2,’ ‘pandemic,’ ‘auditory dysfunction,’ ‘hearing loss,’ ‘tinnitus,’ ‘vestibular dysfunction,’ ‘dizziness,’ ‘vertigo,’ and ‘otologic symptoms.’

    Results:
    Twelve papers met the eligibility criteria and were included in the study. These papers were single group prospective, cross-sectional, or retrospective studies on otolaryngologic, neurologic, or general clinical symptoms of COVID-19 and had used subjective assessments for data collection (case histories/medical records). The results of the meta-analysis demonstrate that the ER of hearing loss (3.1%, CIs: 0.01–0.09), tinnitus (4.5%, CIs: 0.012–0.153), and dizziness (12.2%, CIs: 0.070–0.204) is statistically significant in patients with COVID-19 (Z ≤ −4.469, p ≤ 0.001).

    Conclusions:
    COVID-19 can cause hearing loss, tinnitus, and dizziness. These findings, however, should be interpreted with caution given insufficient evidence and heterogeneity among studies. Well-designed studies and follow-up assessments on otologic symptoms of SARS-CoV-2 using standard objective tests are recommended.
