Patient, disease, and outcome characteristics of benign paroxysmal positional vertigo with and without Meniere’s disease

Abstract

BACKGROUND: Meniere's disease (MD)-associated benign paroxysmal positional vertigo (BPPV) is complex and difficult to diagnose, and reports of its prevalence, pathologic features and outcomes are sparse and conflicting. OBJECTIVE: Report disease characteristics and outcomes associated with the presence of MD in patients with BPPV. MATERIALS/METHODS: A retrospective study of patients with BPPV between 2007 and 2017 at a single, high-volume institution. RESULTS: Of 1581 patients with BPPV identified, 7.1% had MD and 71.9% of those patients had BPPV in the same ear(s) as MD. Patients with MD were more likely to have lateral semicircular canalithiasis (11.6% vs. 5.5%, p = .009) and multiple canalithiasis (7.1% vs. 2.5%, p = .005). MD was associated with an increased rate of resolution of BPPV (p = .008) but also increased time to resolution (p = .007). There was no association between MD and recurrence of BPPV. CONCLUSIONS: MD is associated with lateral canalithiasis. Contrary to prior reports, BPPV in MD can affect either ear and was not associated with poorer outcomes than idiopathic BPPV. SIGNIFICANCE: The largest series to date investigating disease and outcome characteristics for BPPV in MD is presented. These data inform diagnosis and expectations in the management of these complex patients.
