What is BPPV?
Benign Positional Vertigo is the most common vestibular disorder, causing brief (under 1 minute) spinning sensations triggered by specific head positions — rolling over in bed, looking up, or bending forward. It is caused by displaced calcium crystals (otoconia) in the semicircular canals.
The Dix-Hallpike Diagnostic Test
With the patient sitting, the head is turned 45° and the patient is rapidly lowered to lying with the head hanging slightly back. A positive test produces a characteristic torsional nystagmus (eye jerking) within 5–20 seconds that fatigues with repeated testing — confirming BPPV.
Which Canal is Affected?
The posterior semicircular canal is affected in 85–90% of cases and responds to the Epley Manoeuvre. Horizontal canal BPPV (10–15%) responds to the Barbecue Roll Manoeuvre or Log Roll.
Recurrence and Prevention
BPPV recurs in approximately 25–30% of patients within a year. Vitamin D deficiency is a risk factor for recurrence. Annual vestibular checks are recommended for recurrent cases.
