What is the initial treatment for Benign Paroxysmal Positional Vertigo (BPPV)?

Initial Treatment for Benign Paroxysmal Positional Vertigo (BPPV)

Clinicians should treat patients with posterior canal BPPV with a canalith repositioning procedure (CRP), specifically the Epley maneuver, as the first-line treatment. 1, 2

Diagnosis Before Treatment

• Proper diagnosis is essential before initiating treatment:
  • Posterior canal BPPV (80-90% of cases) is diagnosed when vertigo with torsional, upbeating nystagmus is provoked by the Dix-Hallpike maneuver 1, 2
  • Horizontal canal BPPV (10-15% of cases) is diagnosed using the supine roll test when Dix-Hallpike shows horizontal or no nystagmus 1, 2

First-Line Treatment by Canal Type

Posterior Canal BPPV

• The Epley maneuver (CRP) is the first-line treatment with strong evidence and approximately 80% success rate with just 1-3 treatments 1, 2, 3

• The Epley maneuver involves:

  1. Patient sitting upright with head turned 45° toward affected ear
  2. Rapidly laying back to supine head-hanging 20° position for 20-30 seconds
  3. Turning head 90° toward unaffected side for 20 seconds
  4. Turning head and body another 90° (face-down position) for 20-30 seconds
  5. Returning to upright sitting position 1, 2

• The Semont maneuver (Liberatory maneuver) is an effective alternative with similar success rates 2, 4

Horizontal Canal BPPV

• The Barbecue Roll Maneuver (Lempert maneuver) is the first-line treatment 2, 4
• The Gufoni maneuver is an easier alternative that doesn't require identifying the exact affected side 2, 4

Treatment Efficacy

• Success rates for the Epley maneuver for posterior canal BPPV:
  • 90.7% recovery rate after initial maneuver 3
  • 96% recovery rate after second maneuver 3
  • 85% immediate symptom resolution in a larger study of 965 patients 5

Important Clinical Considerations

• Postprocedural restrictions are NOT recommended after CRP for posterior canal BPPV 1, 2
• Patients may experience mild residual symptoms for a few days to weeks after successful treatment 2, 6
• Vestibular suppressant medications (antihistamines, benzodiazepines) should NOT be routinely used for treating BPPV 1, 2
• Observation with follow-up may be offered as initial management in mild cases, but is less effective than repositioning maneuvers 1

Self-Treatment Options

• Self-administered CRP can be taught to motivated patients with 64% improvement rate 2, 6
• Self-administered CRP is more effective than Brandt-Daroff exercises (64% vs 23% improvement) 2

Follow-up and Recurrence

• Patients should be reassessed within 1 month after treatment to document resolution or persistence of symptoms 1, 6
• Recurrence rates are approximately 5-13.5% at 6 months and 10-18% at 1 year 6
• Higher recurrence rates are observed in elderly patients and those with head trauma or vestibular neuropathy 5

Special Considerations and Pitfalls

• Assess patients for modifying factors including impaired mobility, balance issues, CNS disorders, lack of home support, and fall risk 1, 6
• Canal conversion (changing from one type of BPPV to another) can occur in about 6-7% of cases during treatment 2, 6
• Patients with physical limitations may need modified approaches 2, 6
• For persistent symptoms, evaluate for unresolved BPPV, involvement of other semicircular canals, or coexisting vestibular conditions 2, 6
