Abstract:

Purpose: Compare the outcomes of the ocular vestibular stimulated myogenic potential (o-VEMP) and video head impulse (v-HIT) test with the calorie test results. In the assessment of vertigolic patients, the test ranking creates an algorithm. Methods: After a full ear and nasal throat examination of patients with a headache complaint, patients have been performed video-istagmography, o-VEMP and v-HIT tests and all of them have been performed temporary MR examinations. Patients with central pathology considered after odyovestibular examination and radiological imaging, patients with benign paroxysmal positional vertigus and patients diagnosed with vestibular migraine and patients where the planned test battery cannot be applied have been dismissed. The first 30 patients provided criteria were included in the study. Results: In 22 patients (73.3%), canal paralysis was detected. In nine patients (63.3%), the VEMP test was pathologically detected, while the v-HIT test was patologically detected in only 8 patients (26.7%). In 17 of 22 patients with canal paralysis (77.3%), VEMP +/- v-HIT pathology is present. When the two tests were handled together, sensitivity was 77.3 percent specificity and 80.1 percent sensitivity in vestibular hypofunction. The result: the VEMP test and the v-HIT test appear not to be sufficient to replace the calorie test in determining vestibular hypofunction. However, both tests can be used together as a starting test in the evaluation of a vertigual patient. When any of the two tests are achieved pathologically, there will be no need to do calorie tests.
