This is an iatroX educational summary of named United States sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Use the named authority, current FDA labeling, applicable state law, payer rules and local protocol where relevant.

Scope of this summary

Adults with brief positional vertigo compatible with posterior- or horizontal-canal BPPV. The AAO-HNSF 2017 update remains the named US specialty guideline and is supported by a 2026 quality measure, but it is older. Acute continuous vestibular syndromes, pediatric vertigo and patients with contraindications to positioning need separate assessment.

The Bottom Line

  • Diagnose posterior-canal BPPV when a Dix鈥揌allpike maneuver provokes the characteristic vertigo and torsional upbeating nystagmus; repeat on the opposite side if the first side is negative.
  • If the history is compatible but Dix鈥揌allpike produces horizontal or no nystagmus, perform or refer for a supine roll test to assess horizontal-canal disease.
  • Treat confirmed posterior-canal BPPV with a canalith-repositioning maneuver or refer to a trained clinician; observation is an option only with follow-up and safety counseling.
  • Avoid routine brain imaging, vestibular testing and vestibular-suppressant medication when diagnostic criteria are met and no atypical feature suggests another disorder.

Practical clinical workflow

1
Clarify episode duration, positional triggers, hearing symptoms, headache, neurologic symptoms, falls, neck or vascular disease and medicines; examine eye movements, gait and focal neurologic function.
2
Perform the appropriate positional test with cervical and vascular precautions, observe the nystagmus directly and document canal, side and whether the response is typical or atypical.
3
Deliver the canal-specific maneuver, explain transient nausea or disequilibrium and give individualized fall and activity advice rather than rigid postural restrictions unsupported by the guideline.
4
Reassess within the recommended interval for resolution or persistence, repeat or change the maneuver when indicated and investigate vestibular or central causes if the pattern does not behave as BPPV.

Safety boundaries and escalation

  • New focal neurologic deficit, severe gait ataxia, direction-changing or vertical spontaneous nystagmus, acute headache or inability to stand requires urgent evaluation for a central cause.
  • Modify or avoid positional maneuvers in unstable cervical spine disease, recent neck trauma, severe vascular disease or other conditions where rapid head movement may cause harm.
  • Persistent continuous vertigo, new unilateral hearing loss or loss of consciousness is not typical BPPV and should not be managed with repeated repositioning alone.
  • Long-term meclizine or benzodiazepine use can impair compensation, increase sedation and worsen falls; reserve short-term symptom use for a specific indication.

Localization

AAO-HNSF guidance and its 2026 MIPS measure emphasize correct bedside diagnosis and reduced low-value imaging or suppressants. US physical-therapy access, scope rules and payer coverage vary. the older source must be rechecked at each scheduled review.
