What Is The Primary Goal Of Canalith Repositioning Maneuvers in BPPV?

• A. To Dislodge Otoliths Into the Canal
• B. To Abolish Vestibular Function
• C. To Move Canalith Debris Out of the Canal Back to the Otolith
• D. To Surgically Remove Canaliths

Answer: (C)

The main idea is to relocate free-floating otoconia from the semicircular canal back into the utricle, where they belong. When these crystals drift into a canal, they disturb the hair cells with head movements, causing vertigo and nystagmus. Canalith repositioning maneuvers use a specific sequence of head and body positions to use gravity to guide the crystals through the canal and back into the vestibule. Once back in the utricle, they stop provoking abnormal canal signals, and symptoms improve. This is a noninvasive relocation approach rather than destroying vestibular function or removing tissue. The goal is not to push the otoliths further into the canal or surgically remove them.
