What is a key component of the Epley maneuver?

• A. A surgical step to remove debris
• B. A sequence of head and body movements designed to guide debris toward the utricle
• C. Immediate auditory testing after maneuver
• D. No movement of the head is required

Answer: (B)

The essential idea this question tests is that the Epley maneuver relies on a specific sequence of head and body rotations to use gravity to move loose otoconia (debris) out of the semicircular canal and into the utricle. By repositioning the debris from the posterior semicircular canal toward the utricle, the刺激 of the canal during head movements is removed, which helps resolve the vertigo symptoms of BPPV. This non-invasive technique depends on precise positioning and timed holds so the debris can travel along the canal paths and settle in the utricle. So why this option fits best: it directly describes the maneuver’s purpose and mechanism—moving debris toward the utricle through a guided sequence of movements. The other statements aren’t part of the maneuver: there’s no surgical removal involved, it isn’t followed by immediate auditory testing, and moving the head is essential to perform the repositioning.
