BPPV Management
Treat posterior canal BPPV immediately with a canalith repositioning procedure (Epley or Semont maneuver) performed at the bedside—this is the definitive treatment with ~80% success rates in 1-3 sessions, and do NOT prescribe vestibular suppressants or order imaging in uncomplicated cases. 1
Diagnosis First
Confirm the diagnosis with the Dix-Hallpike maneuver: bring the patient from upright to supine with head turned 45° to one side and neck extended 20°. Positive test shows torsional, upbeating nystagmus with vertigo 1. If negative on one side, repeat with the opposite ear down.
If the Dix-Hallpike shows horizontal nystagmus or is negative but history suggests BPPV, perform the supine roll test to assess for lateral (horizontal) canal BPPV 2.
Treatment Algorithm
First-Line: Canalith Repositioning Procedure
- Perform immediately upon diagnosis—either Epley or Semont maneuver 1, 3
- Success rate: approximately 80% with 1-3 treatments 1
- Do NOT impose postural restrictions after the procedure (strong recommendation against) 1
- The choice between Epley vs Semont is based on clinician preference or patient mobility limitations—efficacy is comparable 3
What NOT to Do
- Do NOT prescribe vestibular suppressants (antihistamines, benzodiazepines) routinely—they are ineffective for BPPV and cause unnecessary side effects 1
- Do NOT order brain imaging (CT/MRI) unless there are additional neurological signs inconsistent with BPPV 1
- Do NOT order vestibular testing in straightforward cases 1
Alternative Options (When Appropriate)
- Observation with follow-up is acceptable for initial management, as 20% resolve spontaneously by 1 month and 50% by 3 months 1
- Vestibular rehabilitation (self-administered or with therapist) may be offered as an adjunct 1
Follow-Up and Treatment Failures
Reassess within 1 month to document resolution or persistence 2.
If symptoms persist after repositioning:
- Re-examine for unresolved BPPV (wrong canal identified, incomplete treatment)
- Consider multiple canal involvement 3
- Evaluate for horizontal canal BPPV if not already done 4
- Rule out central vestibular disorders or other peripheral vestibular pathology 2
- Consider comorbidities: migraine, persistent postural-perceptual dizziness 3
Special Populations
Assess for modifying factors before treatment 2:
- Impaired mobility or balance
- CNS disorders
- Lack of home support
- Increased fall risk (especially elderly patients)
In frail elderly or cognitively impaired patients, physical limitations may preclude standard maneuvers 5. Consider referral to specialized vestibular therapy.
Intractable Cases
For same-canal, same-side severe BPPV unresponsive to repeated maneuvers:
- Surgical canal plugging is effective but reserved for truly intractable cases 3, 6
- Vitamin D supplementation reduces recurrence in patients with low serum levels 6
Common Pitfalls
- Misdiagnosing central vertigo as BPPV: BPPV does NOT cause constant severe dizziness unaffected by position, hearing loss, or loss of consciousness 1
- Using medications instead of maneuvers: This is the most common ED management error—imaging and meclizine are not indicated 4
- Imposing unnecessary postural restrictions: These have no additional benefit and reduce patient quality of life 1
- Failing to differentiate canal variants: Anterior canal and cupulolithiasis variants require different approaches 7
