Abstract

Objective: To investigate the correlation of ocular vestibular evoked myogenic potential (o-VEMP ) and video head impulse (v-HIT) test results with caloric test results in peripheral vestibular disorders, and to define an algorithm for investigating vestibular disorders.Methods: All patients underwent an ENT physical examination, an MRI scan, videonystagmography, an o-VEMP test, and a v-HIT test. The patients who had central-type vertigo, PBBV, and vestibular migraine were excluded from the study. Overall, 30 patients were included in the study.Results: Canal paralysis was observed in 22 patients (73.3%). Pathological o-VEMP and v-HIT test results were obtained in 19 (63.3%) and 8 (26.7%) patients, respectively. Pathological o-VEMP or v-HIT was observed in 17 of 22 (77.3%) patients with canal paralysis. Sensitivity and specificity of a combination of o-VEMP and v-HIT test results for detecting canal paralysis were 77.3% and 80.1%, respectively.Conclusion: It does not seem that o-VEMP and v-HIT tests can replace the caloric test to detect vestibular hypofunction. However, these two tests can be used as first-line tests to initiate vestibular evaluation. If one of these two tests shows vestibular hypofunction, there is no need to perform a caloric test

Özet

Amaç: Periferik vestibüler hastalıklarda oküler vestibüler uyarılmış miyojenik potansiyel (o-VEMP) ve video head impulse (v-HIT) test sonuçlarını kalorik test sonuçları ile karşılaştırmak. Vertigolu hastaların değerlendirilmesinde test sıralaması içim bir algoritma oluşturmak.Yöntemler: Baş dönmesi şikayeti ile müracaat eden hastaların tam bir kulak burun boğaz muayenesi yapıldıktan sonra hastaların videonistagmografi, o-VEMP ve v-HIT testlerinin yapılmış ve hepsinin temporal MR tetkikleri yapılmıştır. Odyovestibüler inceleme ve radyolojik görüntüleme sonrasında santral patoloji düşünülen hastalar, benign paroksismal pozisyonel vertigosu olan hastalar ve vestibüler migren tanısı konulan hastalar ve planlanan test bataryasının uygulanamadığı hastalar çalışma dışı bırakılmıştır. Çalışmaya kriterleri sağlayan ilk 30 hasta dahil edilmiştir. Bulgular: Hastaların 22'sinde (%73,3) kanal paralizi tespit edilmiştir. On dokuz hastada (%63,3) VEMP testi patolojik olarak tespit edilirken, v-HIT testi ise sadece 8 hastada (%26,7) patolojik olarak tespit edilmiştir. Kanal paralizi olan 22 hastanın 17 sinde (%77,3) VEMP +/- v-HIT patolojisi mevcuttur. İki test birlikte ele alındığında vestibüler hipofonksiyonu tespit etmede sensitivite %77,3 spesivite ise %80,1 olarak bulunmuştur.Sonuç: VEMP testi ve v-HIT testi vestibüler hipofonksiyonu belirlemede kalorik testin yerini almaya yeterli olabilecek düzeyde gözükmemektedir. Ancak her iki test birlikte vertigolu hastanın değerlendirmesinde başlangıç testi olarak kullanılabilir. İki testten herhangi biri patolojik elde edildiğinde kalorik test yapmaya gerek olmayacaktır
