Characteristics of Post-Repositioning Vestibular Evoked Myogenic Potentials and Their Correlation with Residual Dizziness in Benign Paroxysmal Positional Vertigo
摘要
Abstract
Objective To report characteristics of post-repositioning vestibular evoked myogenic potentials(VEMPs)in patients with benign paroxysmal positional vertigo(BPPV)in comparison with patients without residual symptoms.Methods From August 2018 to October 2022,patients with unilateral posterior or horizontal semicircular canal BPPV were consecutively enrolled at the ENT outpatient departments of four hospitals in Shanghai.One week after successful otolith repositioning,patients were followed up for presence of residual symptoms(such as dizziness,vertigo or unsteadiness).VEMP characteristics were recorded and analyzed using the SPSS 26.0 statistical software.Results A total of 198 patients were enrolled,including 56 with horizontal semicircular canal BPPV and 142 with posterior semicircular canal BPPV.Among them,93(47%)reported residual symptoms after repositioning.The rate of abnormal oVEMPs was significantly higher in patients with residual symptoms compared to those with no residual symptoms(χ2=5.08,P＜0.05).Additionally,in patients with residual symptoms,P1 latency in the affected ear was longer than in those with no symptoms(t=0.87,P＜0.05).The rate of bilateral oVEMP elicitation was lower in patients with residual symptoms than in those with no symptoms(affected ear χ2=22.08,P＜0.001;unaffected ear χ2=16.80,P＜0.001),although there was no significant difference in cVEMP elicitation between the two groups(affected ear χ2=1.3,P=0.254;unaffected ear χ2=1.72,P=0.189).There was no significant difference in the proportion of increased The rate of threshold elevation was more common in the affected ear than in the unaffected ear with cVEMPs(χ2=9.63,P＜0.05),but showed no significant difference with oVEMPs(χ2=0.34,P=0.559).Conclusion BPPV patients with residual symptoms after otolith repositioning exhibited significant differences in VEMP responses compared to those without symptoms.These differences were primarily characterized by lower rates of bilateral oVEMP elicitation and a higher rate of abnormalities in oVEMPs compared to cVEMPs in patients with residual symptoms.关键词
