Treatment of Benign Paroxysmal Positional Vertigo (BPPV)
Canalith repositioning procedures (CRPs) are the first-line treatment for BPPV, with the Epley maneuver being the treatment of choice for posterior canal BPPV, achieving success rates of 90-98% when performed correctly. 1, 2
Diagnosis and Classification
- BPPV is diagnosed when vertigo with characteristic nystagmus is provoked by the Dix-Hallpike maneuver (for posterior canal BPPV) or the supine roll test (for horizontal canal BPPV) 3, 2
- Posterior canal BPPV is most common (85-95% of cases), followed by horizontal canal BPPV (5-15% of cases) 3
Treatment Based on Canal Involvement
Posterior Canal BPPV (Most Common)
Epley maneuver is the first-line treatment with strong evidence, involving these steps 1, 2:
- Patient seated upright with head turned 45° toward affected ear
- Rapidly moved to supine position with head hanging 20° below horizontal
- Head turned 90° to unaffected side
- Head and body turned another 90° (face down position)
- Return to sitting position
Semont maneuver (Liberatory Maneuver) is an effective alternative with comparable efficacy 1, 4
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, 4
Horizontal Canal BPPV
- Barbecue Roll Maneuver (Lempert maneuver) is a first-line treatment, involving rolling the patient 360 degrees in sequential steps 1, 5
- Gufoni maneuver is an effective alternative that may be easier to perform as it only requires identifying the side of weaker nystagmus 5
Treatment Efficacy and Follow-up
- Success rates for CRP (Epley) for posterior canal BPPV are approximately 80.5% by day 7 1
- Patients treated with CRP have 6.5 times greater chance of symptom improvement compared to controls 1
- Patients should be reassessed within 1 month after initial treatment to confirm symptom resolution 2
- Repeated testing and treatment within the same session is safe and effective with low risk of canal conversion 6
Important Clinical Considerations
- Postprocedural restrictions after CRP for posterior canal BPPV are NOT recommended 3, 1
- Vestibular suppressant medications (antihistamines, benzodiazepines) should NOT be routinely used for treating BPPV 3, 1, 2
- Medications may be considered only for short-term management of severe autonomic symptoms (nausea, vomiting) 1, 2
- Approximately 19% of patients may experience post-treatment down-beating nystagmus and vertigo ("otolithic crisis") after the first or second consecutive Epley maneuver 6
Self-Treatment Options
- Self-administered CRP can be taught to motivated patients and appears more effective (64% improvement) than self-treatment with Brandt-Daroff exercises (23% improvement) 1
Management of Treatment Failures
If symptoms persist after initial treatment, patients should be reevaluated for 1, 2:
- Persistent BPPV that may respond to additional repositioning maneuvers
- Involvement of other semicircular canals
- Coexisting vestibular conditions
- Possible CNS disorders
Canal conversion occurs in approximately 6-7% of cases during treatment and requires appropriate repositioning for the newly affected canal 1, 2
Repeat CRPs can achieve success rates of 90-98% for persistent BPPV 1
For cases refractory to multiple CRPs, surgical options like canal plugging may be considered in selected same-canal, same-side intractable severe BPPV 2, 7
