비디오 두부충동검사의 임상적 유용성; 냉온교대 온도안진검사 및 나안 두부충동검사와의 비교

초록

Background and Objectives Video head impulse test system (vHIT) is an easy-to-use testand there are numerous studies showing its efficacy. The aim of the study was to evaluate theclinical usefulness of vHIT as an initial test in determining vestibular hypofunction in patientswith dizziness. Subjects and Method The study recruited 103 outpatients who visited our ear clinic withdizziness. We performed both bedside head impulse test (bHIT), vHIT and bithermal calorictests for 103 patients. Both bHIT and vHIT were consecutively performed in each subject onthe same day by the same examiner. Results The sensitivity of bHIT and vHIT was determined based on the bithermal calorictest results, which showed that vHIT was more sensitive than bHIT. There was a significantnegative correlation between vHIT gain and canal paresis (p＜0.05). Results of some patientsindicated dissociation between vHIT and caloric test. Conclusion T here is a significant correlation between the results of vHIT and caloric test. Although vHIT does not replace the caloric test, it would be useful to evaluate the initial vestibularloss in patients with dizziness.
