Background:Vestibular migraine (VM) is defined as vertigo or dizziness caused by
migraine. The present study was conducted to assess and evaluate the auditory functions in
vestibular migraine patients.
Materials & Methods:156 patients of vestibular migraine of both genders underwent pure
tone audiometry (PTA), impedance audiometry, brainstem evoked response
audiometry (BERA), and distortion product otoacoustic emissions (DPOAE). Parameters
such as type of hearing loss, duration of attack and site of attack was recorded
Results: Out of 156 patients, males were 96 and females were 60. Duration of attack was 0-1
hours in 84, 1-2 hours in48 and >2 hours in 24. Site was front in 78, back in 48 and both sides
in 30. PTA was abnormal in 120 and normal in 36. BERA was abnormal in 114 and normal
in 42. DPOAE was abnormal in 129 and normal in 27. Common symptoms were double
vision in 102, tinnitus in 135, zigzag spots in 84, hearing loss in 36 and darkness in field of
vision in 132. The difference was non- significant (P> 0.05).
Conclusion: Common symptoms in patients with vestibular migraine were tinnitus followed
by double vision, zigzag spots, hearing loss and darkness in field of vision.
