Management of Benign Paroxysmal Positional Vertigo (BPPV)
Canalith repositioning procedures (CRPs) should be the first-line treatment for BPPV, with the Epley maneuver being the most effective treatment for posterior canal BPPV, achieving success rates of approximately 80% with just 1-3 treatments. 1, 2
Diagnosis and Canal Identification
- Diagnose posterior canal BPPV (80-90% of cases) using the Dix-Hallpike test, which provokes vertigo with torsional, upbeating nystagmus 3, 1
- If the Dix-Hallpike test is negative but BPPV is still suspected, perform a supine roll test to assess for horizontal canal BPPV (10-15% of cases) 3, 1
- Differentiate BPPV from other causes of imbalance, dizziness, and vertigo before initiating treatment 1
First-Line Treatment Based on Canal Involvement
Posterior Canal BPPV (Most Common)
Epley maneuver (CRP) - performed in the following sequence: 3, 2
- Patient sits upright with head turned 45° toward the affected ear
- Rapidly lay patient back to supine head-hanging 20° position for 20-30 seconds
- Turn head 90° toward the unaffected side and hold for 20 seconds
- Turn head and body another 90° (facing down) and hold for 20-30 seconds
- Return patient to upright sitting position
Semont maneuver (Liberatory maneuver) - an effective alternative with 71-94% success rates: 3, 2
- Patient sits upright with head turned 45° away from affected ear
- Quickly move to side-lying position on the affected side for 30 seconds
- Rapidly move to opposite side-lying position without changing head position relative to shoulder
- Return to upright position
Horizontal Canal BPPV
- Barbecue Roll Maneuver (Lempert maneuver) - involves rolling the patient 360 degrees in sequential steps 2
- Gufoni Maneuver - for geotropic variant 2
- Modified Gufoni Maneuver - for apogeotropic variant 2
Treatment Efficacy and Follow-Up
- Success rates for CRP (Epley) for posterior canal BPPV are 80.5% negative Dix-Hallpike by day 7 2
- Patients treated with CRP have 6.5 times greater chance of symptom improvement compared to controls 2
- Reassess patients within 1 month after initial treatment to confirm symptom resolution 3, 1
- For patients who fail initial treatment, evaluate for persistent BPPV or underlying peripheral vestibular or CNS disorders 3, 1
Important Clinical Considerations
Do NOT recommend postprocedural restrictions after CRP for posterior canal BPPV - evidence shows they provide minimal additional benefit 3, 1
Do NOT routinely use vestibular suppressant medications (antihistamines, benzodiazepines) for BPPV treatment 3, 1
- These medications can cause significant adverse effects including drowsiness, cognitive deficits, increased fall risk (especially in elderly patients), and interference with central compensation 1, 2
- They may be considered only for short-term management of severe autonomic symptoms (nausea, vomiting) in severely symptomatic patients 2
Self-administered CRP can be taught to motivated patients and appears more effective (64% improvement) than self-treatment with Brandt-Daroff exercises (23% improvement) 3, 2
Alternative Management Options
- Observation with follow-up may be offered as initial management, with spontaneous resolution occurring in 15-85% of patients at 1 month without intervention 3
- Brandt-Daroff exercises can be implemented, though they are less effective than repositioning maneuvers (24% vs 71-74% success rate at 1 week) 2
Special Considerations and Risk Assessment
- Assess patients for modifying factors including impaired mobility or balance, CNS disorders, lack of home support, and increased risk for falling 3, 1
- Elderly patients are particularly at risk for falls with BPPV 2
- Patients with physical limitations may need specialized examination tables or modified approaches 2
Common Pitfalls to Avoid
- Routine use of vestibular suppressant medications delays recovery and has side effects 1
- Unnecessary radiographic imaging and vestibular testing should be avoided unless the diagnosis is uncertain or there are additional symptoms unrelated to BPPV 3, 1
- Canal conversion (changing from one type of BPPV to another) can occur in about 6-7% of cases during treatment 2
- Failing to reassess patients after the initial treatment period can lead to persistent symptoms 2
- Not performing Brandt-Daroff exercises with sufficient frequency (three times daily) can reduce their effectiveness 2
