What nystagmus pattern diagnoses posterior canal BPPV?

Positive Dix-Hallpike: upbeat-torsional nystagmus (upper pole beats toward affected ear) with latency 1-5 seconds, duration <60 seconds, fatigable on repeated testing. Left ear affected if left Dix-Hallpike positive.

What is the Epley maneuver?

Canalith repositioning procedure for posterior canal BPPV: four sequential head positions moving the affected ear (45 degrees rotation to affected side, then 90 degree rotation through supine to opposite side, then sitting up). Success rate 80-90% per session.

When is horizontal canal BPPV suspected?

Horizontal geotropic nystagmus (beating toward ground) on supine roll test = horizontal canal BPPV. Duration >60 seconds distinguishes from posterior canal BPPV. Barbecue roll (log roll) or Gufoni maneuver is the treatment.
