Which semicircular canal is most
commonly involved in BPPV?
commonly involved in BPPV?
Correct Answer - B
Ans. is 'b' i.e., Posterior [Ref Dhingra S
th
/e p. 51]
BPPV is thought to be caused by displacement of otoconia (mineral
crystals) from the vestibule of inner ear into the semicircular canals.
The posterior semicircular canal is most commonly involved, though
superior and horizontal canals canal can also be affected.
Otoconia or ear rocks are small crystals of calcium carbonate
derived structure in the utricle which migrate into semicircular canals
and cause BPPV. While saccules also contains otoconia, they are
not able to migrate into the semicircular canals.
