Abstract

Objectives: This study aims to evaluate the clinical practicability of horizontal video head impulse test in healthy children and to establish normal data. Patients and Methods: A total of 119 children 60 males, 59 females; mean age 10.64±2.8 years; range 6 to 16 years participated in the study, which was conducted between January 2016 and April 2016. Horizontal vestibuloocular reflex VOR was measured with a portable video-oculography device in a seated position in room light. VOR gain was calculated at 40, 60, and 80 milisecond. Refixation saccades were analyzed and participants’ reasons for test failure were recorded. Results: Sufficient and reproducible measurements were acquired for 51 male and 49 female participants mean age 10.64±2.77 years 100/119 children, 84% . There was no significant difference between right and left ears in terms of median gain values. There was a statistically significant difference between median gain values at 40, 60 and 80 milisecond for right and left ears p<0.05 . There was no significant difference between male and female participants in terms of median gain values. Conclusion: Horizontal video head impulse test is a practical and tolerable diagnostic tool for evaluating lateral canal functions in children aged between 6 to 16 years.

Sağlıklı çocuklarda horizontal video baş savurma testinin klinik uygulaması

Abstract

Amaç: Bu çalışmada sağlıklı çocuklarda horizontal video baş savurma testinin klinik uygulanabilirliği değerlendirildi ve normal değerler ortaya kondu.Hastalar ve Yöntemler: Ocak 2016 - Nisan 2016 tarihleri arasında yapılan çalışmaya 119 çocuk 60 erkek, 59 kız; ort. yaş 10.64±2.8 yıl; dağılım 6-16 yıl dahil edildi. Horizontal vestibülooküler refleks VOR oda ışığında, oturur pozisyonda, taşınabilir video-okülografi cihazı ile ölçüldü. VOR kazancı 40, 60 ve 80 milisaniyede hesaplandı. Refiksasyon sakkadları analiz edildi ve katılımcıların testte başarısızlık nedenleri kaydedildi.Bulgular: Yeterli ve tekrarlanabilir ölçümler 51 erkek ve 49 kız katılımcıda yaş ort. 10.64±2.77 yıl elde edildi 100/119 çocuk, %84 . Ortanca kazanç değerleri açısından sağ ve sol kulaklar arasında anlamlı farklılık yoktu. Sağ ve sol kulakta 40, 60 ve 80 milisaniyedeki ortanca kazanç değerleri arasında istatistiksel olarak anlamlı farklılık vardı p
