Abstract
A 56-year-old female with dizziness, imbalance, and a slight floating sensation was evaluated. Her symptoms started after infection with the novel coronavirus (SARS-CoV-2). Routine auditory test (pure tone audiometry), vestibular assessment (videonystagmography), and neurologic test results were in the normal range, but the otolith evaluations, such as cervical vestibular evoked myogenic potentials (cVEMP) and subjective visual vertical tests, showed abnormal findings. The patient underwent a ten-session individualized vestibular rehabilitation program (one session per week). After completing rehabilitation sessions, her chief complaints were alleviated, the performance on computerized posturography was improved, and the abnormal cVEMP amplitude asymmetry between ears disappeared. In conclusion, vestibular disorders can happen after COVID-19 infection, presenting exclusively with isolated otolith dysfunction. In these patients, functional integrity assessment of the whole vestibular system is crucial, and vestibular rehabilitation may be beneficial.
