Name a maneuver used to treat horizontal canal BPPV.

• A. Epley maneuver
• B. Barbecue roll (Lempert) maneuver
• C. Semont maneuver
• D. Brandt-Daroff exercises

Answer: (B)

Horizontal canal BPPV needs a maneuver that moves the otoconia out of the horizontal canal by using gravity as you roll the head and body. The Barbecue Roll (Lempert) maneuver does exactly this: you roll the person supine from side to side through about 360 degrees, guiding debris along the horizontal canal and toward the utricle so it stops stimulating the cupula. This makes it particularly effective for this specific canal involvement.

Other commonly known maneuvers, like Epley and Semont, are designed for the posterior canal and use head-up or rapid side-to-side positioning that targets that canal. Brandt-Daroff exercises are home habituation moves that can help with vertigo more generally but aren’t as targeted or rapid for clearing horizontal canal particles.
