Objective: Our aim was to investigate contralateral suppression of otoacoustic emission for the evaluation of auditory reflex in patients with migraine which is a disease that may cause dysfunction of sensorial modulation.

Methods: Voluntary migraine patients without vestibular symptoms who consulted to Neurology Clinic, and diagnosed according to the IHS 2004 criteria, and healthy volunteers were included in the study. All volunteers underwent complete otorhinolaryngologic and puretone audiometric examinations. Thirty voluntary migraine patients with bilateral otoacoustic emission measurements, and 30 healthy volunteers matched in terms of age and sex were included in the study. Otoacoustic emission measurements were obtained with 65 dB SPL click stimulus with and without mask by masking with contralateral 50 dB SPL broad band noise. Responses were compared between two groups.

Results: Positive result was obtained in suppression tests in 40 of 60 (67%) ears of healthy volunteers and in 30 of 60 (50%) ears of migraine patients. However, there was no statistically significant difference between groups regarding positive suppression frequency and suppression values. Even though a statistically significant difference between migraine patients without vestibular involvement and control group was not seen, there was a decrease in contralateral suppression responses in the migraine group.

Conclusion: Although it is statistically insignificant, we have demonstrated that migraine patients without vestibular symptoms showed a decrease in the suppression values compared to the healthy volunteers. We believe that in new studies with larger series, contralateral otoacoustic emission suppression test can be used as an early tool to diagnose audiovestibular symptoms in migraine patients without any vestibular involvement.
