Benign Paroxysmal Positional Vertigo
Benign paroxysmal positional vertigo (BPPV) is a problem involving the inner ear. Although vertigo can be caused by a number of conditions, BPPV is the commonest cause.
There are small canals called Semicircular canals in the inner ear.The vestibule is the central part of the bony labyrinth. It is separated from the middle ear by the oval window, and communicates anteriorly with the cochlea and posteriorly with the semi-circular canals. Two parts of the membranous labyrinth; the saccule and utricle, are located within the vestibule. The utricle a small membranous sac (part of the membranous labyrinth) and paired with the saccule lies within the vestibule of the inner ear. They are all interconnected. The utricle contains calcium crystals (canaliths) that help it detect movement.Sometimes these crystals detach from the utricle and end up inside the semicircular canals. When these crystals move inside the canals, they may send incorrect signals to your brain about your position. This can make you feel like the world is spinning. This is what most of us understand as vertigo.
There are some exercises that can be tried to push the crystals back to where they came from. One such manoeuvre is called Brandt Daroff Exercise. This video illustrates that exercise.
John Epley suggested another procedure called the John Epley manoeuvre.
