Abstract:
Objective To investigate the clinical application value of blink reflex （BR）， video head impulse test （vHIT）， and vestibular evoked myogenic potentials （VEMP） in vertigo diseases. Methods A retrospective analysis was performed for the electrophysiological results of BR， vHIT， and VEMP in 80 patients with vertigo diseases， among whom there were 37 patients with posterior circulation ischemic isolated vertigo and 43 patients with acute vestibular neuritis， and the imaging findings of patients with posterior circulation ischemic isolated vertigo were also analyzed. Results For the post circulation ischemic isolated vertigo group， the positive rates of BR， vHIT， and VEMP were 75.6%， 0%， and 32.4%， respectively， and for the acute vestibular neuritis group， the positive rates of BR， vHIT， and VEMP were 18.6%， 88.4%， and 55.8%， respectively. Conclusion There is a relatively high positive rate of BR in posterior circulation ischemic isolated vertigo， and vHIT has good sensitivity and specificity in the diagnosis of acute vestibular neuritis， while VEMP can identify peripheral vestibular vertigo. As for the location of infarct lesions in the patients with posterior circulation ischemic isolated vertigo， the patients with cerebellar infarction account for the highest proportion， followed by those with brainstem infarction. The combined use of these three electrophysiological techniques can differentiate posterior circulation ischemic isolated vertigo from acute vestibular neuritis， thereby guiding the early differential diagnosis and treatment of posterior circulation ischemic isolated vertigo.
