In diagnosing BPPV that may involve multiple canals, which statement reflects standard management?

• A. Posterior canal BPPV is treated with Epley maneuvers; horizontal canal BPPV is treated with BBQ maneuvers; anterior canal BPPV requires different maneuvers
• B. Horizontal canal BPPV is treated with BBQ maneuvers; posterior canal BPPV with Epley; anterior canal BPPV with Epley
• C. Horizontal canal BPPV cannot be treated
• D. All canal BPPV are treated identically with Epley

Answer: (A)

The essential idea is that BPPV treatment is guided by which semicircular canal is affected, so the repositioning maneuver must match the canal’s orientation relative to gravity. Each canal has a preferred maneuver to move the displaced otoconia back into the utricle.

For the posterior canal, the Epley maneuver is the standard because its sequence of head and body positions uses gravity to guide debris out of the canal and into the utricle. For the horizontal canal, debris lie in a different plane, so the BBQ roll maneuver—rolling the patient through a full 360 degrees—efficiently moves the debris along the horizontal canal toward the utricle. Anterior canal BPPV sits in a different orientation altogether, so it typically requires a different maneuver (often a variation of the Epley or a reverse/Ealier-positioning technique) rather than the standard posterior-Epley approach.

When multiple canals are involved, clinicians tailor maneuvers to each affected canal rather than applying one method across the board. That’s why the combination described—posterior with Epley, horizontal with BBQ, and anterior needing a different maneuver—is the standard approach.
