Treatment of Benign Paroxysmal Positional Vertigo (BPPV)
The most effective first-line treatment for BPPV is canalith repositioning procedures (CRPs), specifically the Epley maneuver for posterior canal BPPV, which has a success rate of approximately 80% with just 1-3 treatments. 1
Diagnosis and Canal Identification
- BPPV is diagnosed through bedside testing, primarily the Dix-Hallpike test for posterior canal BPPV (most common) and the supine roll test for horizontal canal BPPV 1
- Posterior semicircular canal involvement is most common (73.5%), followed by horizontal semicircular canal (22.5%), and rarely anterior canal or multicanal involvement 2
- Normal medical imaging (scans, x-rays) and laboratory testing cannot confirm BPPV 1
Treatment Based on Canal Involvement
Posterior Canal BPPV (Most Common)
Canalith Repositioning Procedure (Epley maneuver) - First-line treatment with strong evidence 1
- Step 1: Patient seated upright, head turned 45° toward affected ear
- Step 2: Rapidly move patient to supine head-hanging position (20°), maintain for 20-30 seconds
- Step 3: Turn head 90° toward unaffected side, hold for 20 seconds
- Step 4: Turn head and body another 90° (face-down position), hold for 20-30 seconds
- Step 5: Return patient to upright sitting position 1
Liberatory Maneuver (Semont maneuver) - Alternative with good evidence 1
- Step 1: Patient seated upright, head turned 45° away from affected ear
- Step 2: Quickly move patient to side-lying position on affected side, hold for 30 seconds
- Step 3: Rapidly move patient to opposite side-lying position without changing head position relative to shoulder, hold for 30 seconds
- Step 4: Return patient to upright position 1
Horizontal Canal BPPV
Barbecue Roll Maneuver (Lempert maneuver) - First-line for horizontal canal BPPV 1
- Involves rolling the patient 360 degrees in sequential steps 1
Gufoni Maneuver - Alternative for horizontal canal BPPV 1, 3
- Easier to perform as it only requires identifying the side of weaker nystagmus 3
Treatment Efficacy
- Success rates for CRP (Epley) for posterior canal BPPV: 80.5% negative Dix-Hallpike by day 7 1
- Success rates for repositioning maneuvers range from 75% for multicanal to 95.8% for posterior canal BPPV 2
- Patients treated with CRP have 6.5 times greater chance of symptom improvement compared to controls (OR 6.52; 95% CI 4.17-10.20) 1
- A single CRP is >10 times more effective than a week of Brandt-Daroff exercises (OR 12.38; 95% CI 4.32-35.47) 1
Treatment Protocol
- Repeated maneuvers during a single treatment session appear more effective than a single maneuver 4
- For posterior canal BPPV, 91% of cases can be effectively treated with 2 maneuvers or less 5
- For horizontal canal BPPV, 88% of cases can be effectively treated with 2 treatments 5
- Multiple canal involvement or canal conversions may require more treatments 5
Post-Treatment Considerations
- Postprocedural restrictions are NOT recommended after CRP for posterior canal BPPV 1
- Patients may experience mild residual symptoms for a few days to weeks after successful treatment 1
- About 19% of patients may experience post-treatment down-beating nystagmus and vertigo ("otolithic crisis") after the first or second consecutive Epley maneuver 5
Self-Treatment Options
- Self-administered CRP can be taught to motivated patients 1
- Self-administered CRP appears more effective (64% improvement) than self-treatment with Brandt-Daroff exercises (23% improvement) 1
- Self-treatment may be particularly useful for patients with frequent recurrences 4
When to Refer
- Patients who fail to respond to repeated maneuvers should be referred to specialized care 2
- Suspected horizontal or anterior canal BPPV should be examined by a specialist to rule out other neurological conditions 4
- Patients with severe disabling symptoms, history of falls, or difficulty moving should be referred to a healthcare professional experienced in performing repositioning maneuvers 1
Pitfalls and Caveats
- Vertigo and nystagmus throughout the Epley maneuver is not necessarily indicative of treatment success 5
- Canal conversion (changing from one type of BPPV to another) can occur in about 6-7% of cases during treatment 1
- Patients with physical limitations (cervical stenosis, severe rheumatoid arthritis, cervical radiculopathies, etc.) may need specialized examination tables or modified approaches 1
- Clinicians must remain vigilant about post-treatment vertigo to prevent possible falls 5
