Introduction:

Vestibular paroxysmia ist a rare vestibular dysfunction due to neurovascular compression of vestibulocochlear nerve and AICA, PICA, vertebral artery or veins. Complaints are classified with paroxysmal dizziness < 1 min duration and short intervals. Sensitivity of MRT is 95%. Treatment of choice is carbamazepin.

Methods:

The findings of 6 patients classified according to Barany Society recommendation were compared to analyse their load for diagnosis. Pure-tone audiometry, caloric test, vHIT (3D), oVEMP, cVEMP, and spontaneous nystagm were analysed.

Results:

Pure-tone audiometry had pathological findings in 1/6 ipsilateral, 2/6 had lower response of caloric test, 3/6 had sponatneous nystagmus towards ipsilateral side, 2/abnormal response of vKIT (horiz.), in 1/6 no cVEMP kontralateral, 1/6 without VEMP responses bilaterally.

Conclusions:

There was no correlation of vestibular function with positive response to carbazepin in patients with typical complaints and positive MRI findings.
