Contralateral suppression of otoacoustic emissions in migraine patients without vestibular involvement
Ăzet: VestibĂŒler flikayeti olmayan migren hastalarâșnda kontralateral otoakustik emisyon sĂŒpresyonu Amaç: Bu çalâșflmanâșn amacâș duyusal modĂŒlasyon bozuklu€una yol açan migren hastalâș€âș olan kiflilerde iflitme sistemi refleksi ölĂ§ĂŒmĂŒnde kullanâșlan bir test olan kontralateral otoakustik sĂŒpresyon testinin sonuçlarâșnâșn de€erlendirilmesidir. Yöntem: Ăalâșflmaya nöroloji poliklini€ine baflvuran, Uluslararasâș Bafla€râșsâș Derne€i'nin 2004 yâșlâș kriterlerine göre migren tanâșsâș alan ve vestibĂŒler flikayeti olmayan gönĂŒllĂŒ migren hastalarâș ve sa€lâșklâș gönĂŒl-lĂŒler dahil edildi. BĂŒtĂŒn gönĂŒllĂŒlere tam otolojik muayene, saf ses odyometri testi yapâșldâș. Bilateral otoakustik emisyon yanâștâș alâșnan 30 gö-nĂŒllĂŒ migren hastasâș ve karflâșlafltâșrma için yafl ve cinsiyet özellikleri gö-nĂŒllĂŒ hasta grubuna benzeyen 30 sa€lâșklâș gönĂŒllĂŒ çalâșflmaya dahil edildi. Ăalâșflmaya dahil edilen gönĂŒllĂŒlere kontralateral 50 dB SPL genifl bant gĂŒrĂŒltĂŒ ile maske yapâșlarak 65 dB click uyaran ile maskeli ve maskesiz otoakustik emisyon ölĂ§ĂŒmleri yapâșldâș. Her iki gruptan elde edilen veriler karflâșlafltâșrâșldâș. Bulgular: Sa€lâșklâș gönĂŒllĂŒlerin de€erlendirilen 60 kula€âșnâșn 40'âșnda (%67) sĂŒpresyon testi pozitif olarak tespit edilirken migren hastalarâșnâșn de€erlendirilen 60 kula€âșndan 30'unda (%50) sĂŒpresyon testi pozitif olarak tespit edildi. Fakat sĂŒpresyon pozitifli€i oranlarâșnda ve sĂŒpres-yon emisyon de€erlerinde istatistiksel olarak anlamlâș bir fark izlenmedi. âčki grup arasâșnda istatistiksel olarak anlamlâș bir fark olmasa da migrenli grupta kontralateral supresyon cevaplarâșnda azalma izlendi. Sonuç: VestibĂŒler flikayeti olmayan migren hastalarâșnda normal kiflilerle karflâșlafltâșrâșldâș€âșnda istatistiksel olarak anlamlâș olmasa da kontralateral sĂŒpresyon cevaplarâșnda bir azalma izlenmektedir. Daha bĂŒyĂŒk seri içeren yeni çalâșflmalar ile kontralateral otoakustik emisyon testi vestibĂŒler flikayeti olmayan migren hastalarâșnda odyovestibĂŒler flikayetlerin erken tanâșsâșnda kullanabilece€i kanaatindeyiz.

Abstract 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
