The Prevalence of BPPV in Patients with Meniere’s Disease / 听力学及言语疾病杂志

ABSTRACT

Objective To investigate the prevalence of BPPV in patients with Meniere’s Disease(MD),and to investigate the diagnostic and predictive values of VEMP in patients with MD and BPPV.Methods A total of 1 1 6 patients previously diagnosed MD were followed up through telephone about their BPPV-like attacks.We recorded the detailed history of BPPV-like attacks,and provided them with complete Dix-Hallpike and roll tests if patients were on their BPPV-like attacks.Results In all,4 patients'histories supported BPPV,and 4 patients were found with BPPV.The prevalence of BPPV in patients with MD was 3 .4%(4/1 1 6 ).Meniere's symptoms preceded the on-set of BPPV in 8 patients.In 4 confirmed BPPV patients with Meniere's disease,BPPV was limited to the same ear as the MD in 2 cases,and 1 had contralateral BPPV,and 1 was uncertain.Six histories supported or confirmed BP-PVpatients with high abnormal oVEMP rates (5/6).Four in this 5 (80%)had abnormal oVEMP of the same MD ear.The single repositioning procedures can improve vertigo and eliminated positional nystagmus in cases of BPPV associated with MD.Conclusion In the present study,the prevalence of BPPV in patients with MD was 3 .45%.De-tailed medical histories combined with Dix-Hallpike and roll tests and VEMP tests can identify BPPV in patients with MD.
