Overview
Objective: Aim of this study was to define learning curve and to analyse the results of video head impulse test (vHIT) in patients with different etiology of vertigo.
Material and methods: We analyzed results of horizontal vHIT in patients with vertigo examined in period from June 2017 to May 2018. In addition to vHIT we recorded the subjective complaints of patients and results of ENT and other examinations. We sorted out records of vHIT according to quality into three groups: good records, records with artefacts and not-evaluable records. Based on quality of vHIT we defined a learning curve. Further, we analysed numbers of pathological vHIT records and gain in different diagnoses of vertigo. To evaluate results, we applied descriptive statistics, chi-square test, t-test and the test of difference.
Results: We defined our learning curve. There were no not-evaluable records after 80 vHIT examinations. Number of pathological vHIT records was significantly higher in group of patients suffering from vestibular neuritis than in Ménière’s disease and BPPV. Patients with vestibular neuritis in acute stage had more often pathological records on vHIT than patients with vestibular neuritis, who were examined after acute stage of the disease. This difference was not significant (p=0.435). There was significant difference between gain on healthy and diseased side in vestibular neuritis (p<0.01).
Conclusion: There were no not-evaluable records of vHIT after 80 examinations on our learning curve. There were significantly more pathological vHIT records in patients with vestibular neuritis than in patients suffering from Ménièr’s disease or BPPV. There was significantly lower gain on diseased side than on healthy side in patients with vestibular neuritis.
