Objective: This study aimed to analyze static and dynamic vestibular dysfunction in the acute phase of vestibular neuritis (VN) using videonystagmography (VNG). Material and Methods: Twenty-one patients (11 females, 10 males) aged between 20-63 years, who were diagnosed with VN and presented within 72 hours of symptom onset without having received any medical treatment, were included. The VNG test protocol involved the assessment of spontaneous nystagmus, gaze-evoked nystagmus, Head Shake Test (HST), Head Roll Test (HRT), and Dix-Hallpike Test (DH). The slow phase velocity (SPV) of the nystagmus observed in each test was measured and analyzed. Results: The mean age of the participants was 44.14±14.63 years, with no significant age difference between females and males (p>0.05). Spontaneous nystagmus was observed to the right in 10 patients (47.64%) and to the left in 11 patients (52.38%). Correlation analysis showed a moderate positive correlation between spontaneous nystagmus SPV and gaze right nystagmus (p=0.019), as well as left HRT (p=0.005). A strong positive correlation was found between spontaneous nystagmus SPV and HST, supine HRT, right HRT, right DH, and left DH (p=0.001). Conclusion: Our findings suggest that the maximum SPV of spontaneous nystagmus in VN shows strong positive correlations with dynamic vestibular tests, reflecting asymmetric involvement of the vestibular system. Re-recording spontaneous nystagmus in the supine HRT position may improve directionality analysis and aid in the more accurate interpretation of caloric test results.
