BPPV AND PARTICLE REPOSITIONING MANEUVERS
DR.ANITA BHANDARICONSULTANT NEUROTOLOGIST
VERTIGO AND EAR CLINICJAIPUR
The ampulla contains the cupula – a gelatinous mass with the same density as the endolymph. Cupula forms an impermeable barrier across the lumen of the ampulla. Hence the particles in scc may only exit via the end with no ampulla.
SECONDARY CAUSES OF BPPVSECONDARY CAUSES OF BPPVHead injury
Prolonged bed rest
Vestibular neuritis
Meniere’s disease – hydropically induced damage to macula of utricle
Migraine
Ear surgery
BPPV by canal typeBPPV by canal typePosterior Horizontal Anterior
Estimated frequency
81-89% 8-17% 1-3%
Provocative maneuver
Dix Hallpike Supine Roll Test (Pagnini-McClure)
Dix Hallpike
Nystagmus Upbeat, torsional
Horizontal Direction Changing
Downbeat, torsional
POSTERIOR CANAL BPPVPOSTERIOR CANAL BPPVMost common– posterior canal is most gravity dependant in upright and supine position
Once debris enter the post. canal ,the cupula at the shorter most dependant arm trap the debris.
Debris can exit only through the longer arm through the crus commune [non-ampullary]
SEMONTSEMONT’S MANEUVER’S MANEUVER
Liberatory maneuver for pBPPV and cupulolithiasis
Used to overcome otoconia jam after Epley’s maneuver
BRANDT – DAROFF EXERCISESBRANDT – DAROFF EXERCISES
Used as a home program
Indications o Posterior canal cupulolithiasis o Persistant posterior canal canalithiasis
Mechanismo Dislodge debris attached to cupulao Habituation through central compensation
BRANDT – DAROFF EXERCISESBRANDT – DAROFF EXERCISES
Things to remember
o The exercises may dislodge more otoconia from the utricle causing an increase in symptoms.
o May cause multiple canal involvement.
o Important to hold for 30 seconds in each position.
HORIZONTAL SCC BPPVHORIZONTAL SCC BPPV
Pagnini-McClure maneuvre
Geotropic nystagmus – debris are away from ampulla , side showing stronger nystagmus is the side involved
Apogeotropic nystagmus – indicates cupulolithiasis
VANUCCHI MANEUVERVANUCCHI MANEUVER
Forced prolonged positioning
Sleep in lateral position with healthy ear down for 12 hours.
CUPULOLITHIASISCUPULOLITHIASIS
Coined by Schuknetch
Rare , more common in horizontal canal
Caused by otoliths attached to cupula of scc
When cupula is horizontal no vertigo
When non-horizontal constant input persistant dizziness
Nystagmus : persistant non-fatiguable as long as patient is in the same position
ANTERIOR CANAL BPPVANTERIOR CANAL BPPV
Anterior canal BPPV is usually transitory and most often the result of “canal switch” that occurs in the course of treatment more common forms of BPPV
SUBJECTIVE BPPVSUBJECTIVE BPPV
No nystagmus is detected but patient feels dizzy on provocative tests
PRP beneficial
Reasonso Subtle nystagmus o Fatigued nystagmuso Inadequate neural signal to stimulate the VOR
CONTRAINDICATIONS OF CONTRAINDICATIONS OF PARTICLE REPOSITIONINGPARTICLE REPOSITIONINGCervical spine problems
Uncontrolled hypertension
Retinal detachment
OTHER CAUSES OF OTHER CAUSES OF POSITIONAL NYSTAGMUSPOSITIONAL NYSTAGMUS
Direction changing nystagmus – central
Down beating positional nystagmus – nodulus
Down beating nystagmus on Dix-Hallpike – anterior canal BPPV . Treated by Epley’s maneuvre
