    The study compared functional head impulse test (FHIT) and video head impulse test (vHIT) in patients with interictal Ménière’s disease and inferior vestibular neuritis.

  • 2

    In Ménière’s disease, FHIT showed significant lesion-side reduction, while vHIT gains remained preserved, indicating a dissociation between these tests.

  • 3

    The FHIT abnormality rate in Ménière’s disease was 73%, compared to 18% in vHIT, highlighting the potential of FHIT in assessing functional vestibular asymmetry.

  • 4

    Inferior vestibular neuritis exhibited significant reduction in posterior canal vHIT gain, with no significant laterality observed in FHIT.

  • 5

    Findings suggest that FHIT may reflect functional vestibular changes in Ménière’s disease, distinct from structural nerve lesions seen in inferior vestibular neuritis.
