What is the name of the maneuver used to reposition canaliths in BPPV?

• A. Canalith repositioning (Epley) maneuver
• B. Caloric irrigation
• C. Vestibular rehabilitation training
• D. Head-shake test

Answer: (A)

The maneuver used to reposition canaliths in BPPV is the canalith repositioning maneuver, commonly known as the Epley maneuver. It works by guiding the loose otoconia (the canaliths) out of the semicircular canal and into the utricle, where they no longer trigger vertigo with head movements. This is achieved through a sequence of head and body positions that use gravity to move the debris along the canal and into the vestibule. Many patients experience relief after the maneuver, and some may need a repeat session. Caloric irrigation is a test that stimulates the vestibular system to elicit nystagmus for evaluation, not to move the canaliths. Vestibular rehabilitation training helps the brain compensate for balance issues rather than physically relocating otoconia. The head-shake test is a provocative assessment for vestibular function, not a treatment to reposition debris.
