Abstract:
Introduction: Benign Paroxysmal Positional Vertigo (BPPV) is a common and treatable peripheral vestibular disorder, unfortunately there is no information on BPPV treatment in Mexico. The objective was to determine management practices of BPPV in Mexico.
Methods: An anonymous multicenter online survey to Mexican Neurotologists was carried out from October to December 2020. Google forms software, Microsoft Excel and IBM SPSS Statistics version 21 were used. Categorical variables were described with frequencies and percentages.
Results: Forty responses were obtained, subjects were between 40 to 49 years old (42.5%). Mexican neurotologists preferred the Epley Maneuver (75%) to treat posterior canal BPPV, 45% performed a single maneuver at each visit and only 15% combined maneuvers. Barbecue maneuver (47.5%) was the most used maneuver for the horizontal canal geotropic variety and Gufoni (40%) for the apogeotropic variety. Yacovino maneuver was performed by 55% of neurotologists for superior canal BPPV. Pharmacological treatment was generally not indicated (55%) before the maneuver. Sleeping in a semi fowler position was recommended by 82.5% of participants. Refractory BPPV was treated by 40% of neurotologists with Brandt Daroff exercises until no further nystagmus was evident, 47.5% of subjects indicated in these cases an electronystagmography and 32.5% performed a magnetic resonance imaging. Only 25% of participants indicated or performed surgical treatment for BPPV.
Conclusions: Mexican neurotologists preferred a single Epley Maneuver for posterior canal BPPV, Barbecue for geotropic horizontal canal BPPV, and Gufoni for apogeotropic variant. Refractory BPPV was generally treated with Brandt Daroff. A low percentage of neurotologists perform surgical treatment.
