1
Q

BBPV

A

Peripheral cause of vertigo (problem located in the ear rather than in the brain)

2
Q

Features

A

Vertigo triggered by change in head position

May be associated with nausea

Lasts 10-20 seconds

NO hearing loss or tinitus

3
Q

Pathophysiology

A

Calcium carbonate crystals (otoconia) become displaced into the semicircular canals

Most often in the posterior semicircular canal

Disrupt the flow of endolymph through the canals, confusing the vestibular system

4
Q

Dix-Hallpike Manoeuvre

A

Moves patient so that endolymph moves through semicircular canals and triggers vertigo in patients with BPPV

Make sure they have no neck pain or pathology before

5

Epley manoeuvre

A

Used to treat BPPV

Moves crystals in the semicircular canals into position that does not disrupt enolymph flow
