Summary

Acute vertigo accounts for around 4% of emergency room visits. Triggered episodic vestibular syndrome is the most commonly encountered symptomatic context. BPPV (Benign Paroxysmal Positional Vertigo) is the main cause, representing 40-50% of the vertigo cases assessed in emergency departments. It results from the migration of calcium carbonate particles (otoliths), from the sticky membrane of the utricle and saccule of the inner ear, to one of the 3 semicircular canals (SCC), posterior, horizontal or lateral, and anterior. It occurs idiopathically with head movement, through degeneration, or following head trauma. The otolith impulse causes the endolymph to move, temporarily and aberrantly displacing the cup of the affected canal, resulting in the transmission of erroneous information to the vestibular nuclei. This leads to the sudden onset of vertigo and eye deviation, resulting in transient nystagmus. The location of the displaced otoliths determines the variant of BPPV: BPPV of the posterior semicircular canal is the most common (around 65% of BPPVs), followed by BPPV of the horizontal canal, while BPPV of the anterior canal is rare, as it resolves spontaneously and rapidly. Although a benign condition, BPPV leads 9 times out of 10 to a medical consultation, interruption of daily activities, or sick leave. Untreated, it will usually recur, and can impact on patients' quality of life.
