Which maneuver is used to treat posterior canal BPPV?

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

Answer: (D)

Posterior canal BPPV happens when tiny crystals (otoconia) drift into the posterior semicircular canal and cause vertigo with head movements. The Epley canalith repositioning maneuver is designed to move those crystals out of the posterior canal and into the utricle, using a precise sequence of head and body positions so gravity guides the debris toward the utricle. This direct repositioning often relieves symptoms quickly and is the standard first-line treatment for this form of BPPV. Brandt-Daroff exercises are home habituation moves that may help with symptoms over time but aren’t targeted repositioning for this canal. The Semont maneuver can treat posterior canal BPPV but is less commonly used as the first choice, while the Barbecue roll (Lempert) targets horizontal canal BPPV, not the posterior canal.
