AI Article Synopsis
- This study looked at differences in two tests (vHIT and cVEMP) between patients with two conditions: vertebrobasilar insufficiency (VBI) and Meniere's disease (MD), who both experience dizzy spells.
- It involved 64 patients total and aimed to see how their test results compared when they had vertigo attacks.
- The results showed that both groups had similar abnormal test results, meaning these tests can help doctors diagnose VBI but didn't show big differences between the two conditions.
Article Abstract
Background And Purpose:
This prospective study aimed to investigate diffe-rences in video head impulse test (vHIT) and cervical vestibular evoked myogenic poten-tial (cVEMP) findings between patients with vertebrobasilar insufficiency (VBI) and Meniere’s disease (MD) who experience episodic vertigo attacks.
.Methods:
A total of 27 patients with VBI and 37 patients with MD were enrolled into the study in a tertiary referral center. Inclusion criteria consisted of patients with a minimum of two previous vertigo attacks, unaccompanied by any neurological symptoms during an attack. All patients underwent horizontal canal h-vHIT and c-VEMP assessments following pure sound audiometric examinations. First, vHIT and cVEMP results for low and high flow sides in VBI patients were analyzed. Subsequently, data from the low-flow side in VBI patients and the affected side in MD patients were compared.
.Results:
The mean vHIT values for low and high-flow volume sides in VBI patients were 0.68 and 0.88, respectively. In MD patients, mean vHIT values for affected and healthy sides were measured as 0.77 and 0.87, respectively. Abnormal results were observed in 66.7% of VBI patients and 51.4% of MD patients, with no statistically significant difference between the findings (p> 0.05). Upon examining the affected side, c-VEMP responses were absent in 41% of MD patients and 48% of VBI patients, with no statistically significant difference between the groups (p> 0.05).
.Conclusion:
vHIT and cVEMP assessments can be utilized as supplementary tools to radiologic investigations for the clinical diagnosis and follow-up of VBI. However, no significant differences were observed between vHIT and cVEMP findings in patients with MD and VBI.
