What is the initial management for a patient with benign positional paroxysmal vertigo (BPPV)?

Management of Benign Paroxysmal Positional Vertigo (BPPV)

The initial management for BPPV is the canalith repositioning procedure (CRP), specifically the Epley maneuver for posterior canal BPPV, which should be performed immediately upon diagnosis without any imaging, vestibular testing, or medications. 1, 2, 3

Diagnostic Confirmation Before Treatment

• Perform the Dix-Hallpike maneuver to diagnose posterior canal BPPV (85-95% of cases), looking for torsional upbeating nystagmus when bringing the patient from upright to supine with head turned 45° to one side and neck extended 20°. 1, 2

• If the Dix-Hallpike is negative but BPPV is suspected, perform the supine roll test to assess for lateral (horizontal) semicircular canal BPPV, which accounts for 10-15% of cases. 1, 2

• Do not order imaging or vestibular testing in patients who meet diagnostic criteria for BPPV unless there are additional neurological signs inconsistent with BPPV (abnormal cranial nerves, severe headache, visual disturbances). 1, 2, 3

Immediate Treatment Algorithm by Canal Type

Posterior Canal BPPV (85-95% of cases)

Perform the Epley maneuver immediately with the following steps: 1, 2, 3

1. Patient sits upright with head turned 45° toward the affected ear
2. Rapidly lay patient back to supine head-hanging 20° position for 20-30 seconds
3. Turn head 90° toward the unaffected side, hold 20-30 seconds
4. Roll patient onto side with nose pointing down, hold 20-30 seconds
5. Return patient to upright sitting position

• Success rate: 80% after 1-3 treatments, increasing to 90-98% with repeat maneuvers if needed. 2, 3, 4
• Alternative option: Semont (Liberatory) maneuver has 94.2% resolution rate at 6 months. 2, 5

Horizontal Canal BPPV (10-15% of cases)

• For geotropic variant: Perform Barbecue Roll (Lempert) maneuver (50-100% success rate) or Gufoni maneuver (93% success rate). 2
• For apogeotropic variant: Perform Modified Gufoni maneuver (patient lies on affected side). 2

Critical Post-Treatment Instructions

Patients can resume normal activities immediately after treatment. 1, 2, 3

• Do not recommend postprocedural postural restrictions (no head elevation, no sleeping on affected side, etc.) as strong evidence shows they provide no benefit and may cause unnecessary complications. 1, 2, 3

Medication Management: What NOT to Do

Do not prescribe vestibular suppressant medications (meclizine, antihistamines, benzodiazepines) as primary treatment for BPPV. 1, 2, 3

• These medications have no evidence of effectiveness as definitive treatment for BPPV. 2
• They cause significant adverse effects including drowsiness, cognitive deficits, and increased fall risk (especially in elderly patients). 2
• They interfere with central compensation mechanisms. 2
• Exception: May consider short-term use only for severe nausea/vomiting in severely symptomatic patients refusing other treatment. 2

Assessment of Modifying Factors Before Treatment

Evaluate all patients for factors that modify management: 1, 2, 3

• Impaired mobility or balance
• CNS disorders
• Lack of home support
• Increased fall risk (BPPV increases fall risk 12-fold, particularly in elderly patients) 2
• Cervical spine pathology (severe cervical stenosis, radiculopathy, severe rheumatoid arthritis) - these patients may need modified approaches or Brandt-Daroff exercises instead 2, 3

Follow-Up and Treatment Failure Management

Reassess patients within 1 month after initial treatment to document resolution or persistence of symptoms. 1, 2, 3

If Symptoms Persist After Initial Treatment:

1. Repeat the diagnostic test (Dix-Hallpike or supine roll test) to confirm persistent BPPV 2
2. Perform additional repositioning maneuvers - repeat CRPs achieve 90-98% success rates 2, 3, 6
3. Check for canal conversion (occurs in 6-7% of cases - posterior canal may convert to lateral canal or vice versa) 2
4. Evaluate for multiple canal involvement or bilateral BPPV 2, 7
5. Consider coexisting vestibular pathology if symptoms are provoked by general head movements or occur spontaneously 2
6. Rule out CNS disorders masquerading as BPPV, especially if atypical features are present 2

Adjunctive Therapy Options

Vestibular Rehabilitation Therapy (VRT)

May offer VRT as adjunctive therapy (not as substitute for CRP), particularly beneficial for: 2, 3

• Patients with residual dizziness after successful CRP
• Postural instability or heightened fall risk
• Reduces recurrence rates by approximately 50% 2

Self-Treatment for Motivated Patients

Self-administered Epley maneuver can be taught after at least one properly performed in-office treatment, with 64% improvement rate (compared to 23% with Brandt-Daroff exercises). 2, 3

Common Pitfalls to Avoid

• Ordering unnecessary imaging or vestibular testing when diagnostic criteria are clearly met 2, 3
• Prescribing vestibular suppressants as primary treatment 2, 3
• Recommending postprocedural restrictions after CRP 1, 2, 3
• Not performing the maneuvers quickly enough during treatment, which reduces effectiveness 2
• Failing to reassess patients after initial treatment period 2, 3
• Not addressing fall risk immediately, especially in elderly patients 2

Patient Education

Educate patients regarding: 1

• Impact of BPPV on their safety (particularly fall risk)
• High recurrence rates (10-18% at 1 year, 30-50% at 5 years) 2
• Each recurrence should be treated with repeat CRP, which maintains the same high success rates 2
• Importance of follow-up within 1 month 1, 2
