To analyze the correlation of vestibular symptoms such as dizziness and vertigo in patients following Covid-19 infection, evaluate their onset, duration, and vestibular findings, and compare the etiology with that of vertigo cases tested negative for Covid-19.

Covid-19 has been associated with a variety of long-term symptoms in patients, including dizziness and vertigo. The specific onset timing, duration, and vestibular characteristics of these symptoms post-Covid-19 have not been extensively documented, and the reported long-term consequences remain controversial. There is a pressing need to standardize these findings by providing comprehensive data from all countries. 

This study included patients from 2020 to June 2021 who have tested positive for Covid-19 and present with dizziness or vertigo symptoms post-infection. The control group consisted of age- and gender-matched individuals without a history of Covid-19. Patients have undergone ear examinations, vestibular maneuvers, Video Head Impulse Test (vHIT), Videonystagmography (VNG), and audiological tests. Statistical analysis was performed with SPSS (v20.0.).

The study included 39 Covid-19 positive patients and 35 controls. The mean age was 42.12±10.85 years for the Covid-19 group and 45.94±14.69 years for the controls (p=0.21). Gender distribution was similar (p=0.41). The mean time since Covid-19 positivity was 3.02±2.03 months. VNG results showed no pathology in 94.8% of Covid-19 patients vs. 82.9% of controls (p<0.001). In the vHIT, significant differences in bilateral and left-side pathologies were noted (p=0.002). Dix-Hallpike/Roll test results also differed significantly (p<0.001). No significant correlations were found between the time since Covid-19 infection and the test results.
