Objectives: This study aims to determine the normal values for ocular vestibular evoked myogenic potentials in response to air conducted stimuli in healthy adults. Patients and Methods: Thirty-six healthy adult participants with no ear complaints were enrolled. Ocular vestibular evoked myogenic potential tests were performed to all participants. Latency and amplitude values of the waves were recorded. Results: The mean N1 latency was 9.62±2.02 4.30-16.00 msec and the mean P1 latency was 14.90±2.33 9.0-21.00 msec. The mean amplitude was 3.36±1.36 1.06-8.48 µV. There was a positive correlation between N1 and P1 latencies and age r=242, p=0.0359 for N1; r=250, p=0.030 for P1 . Conclusion: Ocular vestibular evoked myogenic potentials can be obtained easily and can be used in the evaluation of vestibular disorders. However, the effect of age should be considered when interpreting results.

Amaç: Bu çalışmada sağlıklı erişkinlerde hava yolu uyaranına karşı verilen yanıtta oküler vestibüler uyarılmış miyojenik potansiyeller için normal değerler belirlendi.Hastalar ve Yöntemler: Çalışmaya işitme sorunu olmayan 38 sağlıklı erişkin katılımcı dahil edildi. Tüm katılımcılara oküler vestibüler uyarılmış miyojenik potansiyel testleri yapıldı. Dalgaların latans ve amplitüd değerleri kayıt edildi.Bulgular: Ortalama N1 latansı 9.62±2.02 4.30-16.00 msn. ve ortalama P1 latansı 14.90±2.33 9.0-21.00 msn. idi. Ortalama amplitüd değeri 3.36±1.36 1.06-8.48 µV idi. N1 ve P1 latansları ile yaş arasında pozitif bir ilişki vardı N1 için r=242, p=0.0359; P1 için r=250, p=0.030 .Sonuç: Oküler vestibüler uyarılmış miyojenik potansiyeller kolayca elde edilebilir ve vestibüler hastalıkların değerlendirilmesinde kullanılabilir. Ancak, sonuçların değerlendirilmesinde yaşın etkisi göz önünde bulundurulmalıdır
