Dr. Manish Kumar Tailor | |
Background: Vertigo or dizziness brought on by a migraine is known as vestibular migraine (VM). Since one-third of individuals with migraine headaches also experience dizziness, the prevalence of VM can be approximated to be around 3% of the general population. The present study was conducted to assess auditory functions in vestibular migraine patients. Materials & Methods: 86 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, site and duration of attack was recorded. Results: Out of 86 patients, 50 were males and 36 were females. Site of attack was front in 45, back in 33 and both in 8 patients. Duration of attack was 0-1 hours in 48, 1-2 hours was 22 and >2hours in 6 cases. DPOAE was abnormal in 59 and normal in 27 cases. PTA was abnormal in 61 and normal in 27. BERA was abnormal in 38 and normal in 14. The difference was significant (P< 0.05). Common symptoms were zig zag spots in 47, hearing loss in 10, double vision in 23, tinnitus in 31 and darkness in field of vision in 8 cases. The difference was non- significant (P> 0.05). Conclusion: In most of vestibular migraine patients, DPOAE, PTA and BERA was abnormal. |
