    Purpose: To evaluate vestibular function in patients with sudden hearing loss (SS) using cervical and ocular vestibular evoked myogenic potential (respectively, cVEMP and oVEMP), video head impulse test (vHIT), and caloric test. In addition, this study aims to assess the correlation between dizziness with vestibular tests and the correlation between vestibular tests and hearing recovery. Methods: This is an observational, longitudinal, prospective study comprising consecutive patients with SS who attended the emergency room and the outpatient clinic of the Otorhinolaryngology and Head and Neck Surgery Department of the Universidade Federal de São Paulo (UNIFESP) and met the eligible criteria, from November 2019 to March 2021. An otorhinolaryngologic assessment was performed, including audiometry, cVEMP, oVEMP, vHIT and caloric test. Audiometry was performed at the presentation and at the end of follow-up. A p-value ≤ 0,05 was considered statistically significant. Results: Seventeen patients were included in the study, 9 (52.94%) males and 8 (47.06%) females, with a mean age of 45.4 ± 11.1 years. The right side was affected in 9 patients (52.94%) and the left side in 8 (47.06%). Five patients (29,41%) presented dizziness and 15 (88,23%) tinnitus. All participants underwent vestibular assessment through cervical and ocular VEMP and vHIT, and 13 of them were evaluated by caloric test. cVEMP was abnormal in 5 (29.41%) patients, while oVEMP was abnormal in eleven (64.71%). vHIT and caloric test were abnormal in 7 (41.18%) and 5 (38.46%) patients, respectively. There was no statistically significant correlation between clinical data and vestibular tests or hearing recovery, neither between vestibular tests and hearing recovery. Conclusion: oVEMP, cVEMP, vHIT and caloric test revealed vestibular involvement in some patients. However, abnormal vestibular tests or its combination were not correlated with hearing recovery in SS.
