(530) Use of Omniax Repositioning Chair for the Treatment of BPPV

Introduction: BPPV is the most common form of vertigo in the Neurotology Clinic. The purpose of this study is to retrospectively review a large number of refractory and atypical cases that required use of the Omniax chair and study the success and recurrence rate in comparison to standard office repositioning maneuvers.

Methods: This was a retrospective review of adult patients who were referred to a Neurotology private practice group for treatment of BPPV with the Omniax chair. The purpose of the study is to define the role of the Omniax chair in patients who have refractory and/or atypical BPPV cases. Prior particle positioning maneuvers performed, canals affected, number of treatments required, and recurrence post ominax was recorded. We expected that the use of the Omniax would improve atypical and refractory cases of BPPV for patients with superior and horizontal canal BPPV (atypical BPPV) and those with refractory cases of posterior canal BPPV. Improved outcomes include both resolution of symptoms and improvement of Omniax testing.

Results: 100 patient charts were reviewed to date. Initial data evaluation showed that patients presenting with atypical BPPV required more Omniax treatments than patients presenting with posterior canal BPPV. Patients with multiple canals affected were more likely to require multiple visits for resolution of symptoms. Patients with decreased mobility due to back and neck disorders were more likely to be referred to Omniax treatment due to inability to perform in office repositioning maneuvers. 36 of the 100 patients required a second Omniax treatment for recurrent or refractory BPPV.

Conclusions: The purpose of this study was to evaluate the role of the Omniax chair in a private practice neurotology office setting. Patients referred for atypical BPPV were more likely to require multiple visits for resolution of symptoms. Patients with decreased mobility were also more likely to undergo Omniax evaluation prior to in office repositioning maneuvers. This data can be further used to assist otolaryngologists in referring cases of atypical or refractory BPPV for evaluation at a facility with an Omniax chair.
