Benign Paroxysmal Positional Vertigo
(BPPV)
Risk Factors:
• Advancing age
• Head trauma
• Migraine
• Inner ear disease
• General anaesthesia
BPPV – How to diagnose
• Hallpike Manouevre
• http://www.youtube.com/watch?v=ttgaqpIv_
wM
• Typical rotatory nystagmus
• Careful explanation
BPPV – How to Treat
• Epley Manoeuvre

BPPV – How to Treat
• Semont Manoeuvre
Final Part of Case
• More careful questioning
elicited facial numbness
and slight clumsiness of
left hand
• On admission to hospital
the patient;
• Sustained nystagmus on
positioning
Take-Home Messages

Vestibular problems common
Ensure no red flags
Vestibular sedatives short term use only
