Podcast 1020: Benign Paroxysmal Positional Vertigo (BPPV)

Contributor: Alec Coston, MD

Educational Pearls:

Benign Paroxysmal Positional Vertigo (BPPV)

• Common inner ear condition that can cause dizziness

• Diagnosis of BPPV can help to avoid admissions and extra imaging

• Three categories: positional, horizontal, and anterior

• Positional is the most common 

• Dizziness is not a positive indicator, a torsional nystagmus must be induced

• Dix's hallpike maneuver is done to diagnose and an epley maneuver is then used for treatment 

• Horizontal 

• Usually determined to be the case if the vertigo seems positional and the dix hallpike does not work. A supine roll test would then be done to help diagnose.

• Instead of a rotational nystagmus, a unilateral horizontal nystagmus is expected. The two patterns are termed geotropic and apogeotropic.

• Geotropic means the fast phase beats toward the ground, and is treated by a barbeque roll maneuver. Apogeotropic means the fast phase beats toward the ceiling, and is treated by Gufoni maneuver.

• Anterior is more rare

• Most cases require neuro consults

• Determined by attempting to induce a down-beating nystagmus, which is a higher risk nystagmus.

• Treatment is tilting their head back up in a similar way

• Inducing the nystagmus is not sided and is more central
