Bppv

In Dix Hallpike maneuver the patient is placed

• In supine position

• In prone position

• In sitting position

• In supine position with head hanging down from the edge of the couch

Frenzel's glasses should be used by

• Observer

• Patient

• Patient and observer

• By everyone present in the examination room

BPPV was first described by:

• Barany

• Neffson

• Paperella

• Portmann

Singular neurectomy is useful in the mangement of intractable BPPV because

• Singular nerve supplies the posterior semicircular canal

• Singular nerve supplies all three semicircular canals

• Singular nerve supplies utricle, saccule and lateral semicircular canals

• Singular nerve supplies the entire labyrinth

After repositioning maneuvers patient is asked to 

• Sleep without a pillow for 2 days

• Sleep with head turned to one side (affected) for 2 days

• Sleep with head elevated to 45 degrees for 2 days

Vibrator therapy for BPPV is contraindicated in patients with

• COPD

• Retinal detachment

• Ear discharge

• Meniere's disease

Lateral canal BPPV can be identified by

• Dix Hallpike maneuver

• Doll's eye movement

• Lack of righting reflex

• Variation of Dix Hallpike maneuver

In Epley Maneuver the patient is placed in

• Dix Hallpike position

• Prone position

• Supine position with head raised by 30 degrees

• Prone position with head hanging out from the edge of the couch

Which repositioning maneuver can be perfromed by the patient himself?

• Dix Hallpike Maneuver

• Semont's maneuver

• Brandt Droff maneuver

• Ruby maneuver

In Dix Hallpike position

• The posterior canal is horizontal to earth's vertical plane

• The lateral canal is vertical to the earth's axis

• The posterior canal is in the earth's vertical plane

• The superior canal is in the earth's vertical plane

Unique features of Nystagmus of BPPV are

• Very short latency

• Directional features

• Brief duration

• Prolonged duration

• Reversibility on coming out of provoking position

• Irreversible

Canal lithiasis theory was proposed to account for BPPV by

• Schuknecht

• Hall and Ruby

• Dix Hallpike

• Paperella

Hall and Ruby described two types of BPPV: BPPV with   __________ Nystagmus BPPV with ____________ Nystagmus

Name the surgical procedures used in the management of Intractable BPPV.

• Singular neurectomy

• Posterior semicircular canal plugging procedure

• Modified radical mastoidectomy

• Grommet insertion
