ABSTRACT
Registration of ocular and cervical vestibular evoked myogenic potentials (oVEMPs and cVEMPs) reflects the function of otolith receptors sacculus and utriculus. Benign paroxysmal positional vertigo (BPPV) is a disease of the inner ear as a result of the utriculus disfunction and migration of otoliths into semicircular channels. OBJECTIVE:
To study the function of otolith receptors (sacculus and utriculus) with using VEMPs registration in patients with first-time and recurrent posterior semicircular canal BPPV before and after repositional maneuvers. MATERIAL ANDMETHODS:
Registration and comparison of the results of oVEMPs and cVEMPs were performed in 50 patients with first-time posterior semicircular canal idiopathic BPPV and 26 patients with recurrent posterior semicircular canal BPPV before and after repositional treatment. RESULTS ANDDISCUSSION:
Clinically significant asymmetry of the amplitude of oVEMPs before treatment was recorded in 14 (38%) of patients with first-time BPPV and in 15 (57.7%) of patients with recurrent BPPV; cVEMPs - in 6 (12%) of patients with first-time BPPV and in 6 (23.1%) of patients with recurrent BPPV. Successful repositional treatment did not affect the amplitude of cVEMPs in any of the groups of patients, but led to a significant increase in the amplitude of oVEMPs on the affected side in patients with first-time BPPV. In patients with recurrent BPPV, despite the absence of symptoms of otolithiasis, the asymmetry of the amplitude of oVEMPs persisted during remission (p<0.05), which can be considered as a prognostically unfavorable factor of disease recurrence.Palavras-chave
