The Epley canalith repositioning manoeuvre is most effective for which variant of BPPV?
- A Lateral (horizontal) semicircular canal — cupulolithiasis variant
- B Superior (anterior) semicircular canal BPPV
- C Posterior semicircular canal — canalolithiasis (free-floating debris in canal) ✓
- D Bilateral posterior canal BPPV simultaneously
Explanation
The Epley manoeuvre is the evidence-based treatment of choice specifically for posterior semicircular canal canalolithiasis BPPV — the most common form. It moves the displaced otoconia from the posterior canal back into the utricle through a series of four sequential head positions. Cupulolithiasis of the lateral canal requires the Gufoni or barbecue roll manoeuvre. Superior canal BPPV is rare and may require the reverse Epley or deep-head-hanging manoeuvre.
