Treatment Options for Benign Paroxysmal Positional Vertigo (BPPV)
Canalith repositioning procedures (CRPs) are the first-line treatment for BPPV, with a success rate of 80-90% after just 1-2 treatments. 1
Diagnostic Approach
Before treatment, proper diagnosis is essential:
- The Dix-Hallpike test is the gold standard for diagnosing posterior canal BPPV
- The supine roll test is used for lateral (horizontal) canal BPPV 1
- Unnecessary imaging (CT or MRI) is not needed to diagnose BPPV 1
First-Line Treatment: Canalith Repositioning Procedures
Posterior Canal BPPV (most common)
- Epley maneuver: Highly effective with 93.4% success rate 2
- Semont maneuver: Level 1 evidence treatment, comparable efficacy to Epley 3
Horizontal Canal BPPV
- Gufoni maneuver: Level 1 evidence treatment 3
- Barbecue roll maneuver: Effective alternative 1
- Shortened Forced Position (SFP): Lying on the side where vertigo and nystagmus are less intense for 1 hour shows 71.7% improvement or resolution 4
Treatment Considerations
- Multiple treatments may be needed in a single session
- 91% of posterior canal BPPV cases can be effectively treated in 2 maneuvers or less 5
- 88% of horizontal canal BPPV cases can be effectively managed with 2 treatments 5
- Bilateral, multiple canal involvement, or canal conversions may require more treatments 5
Pharmacologic Interventions
For Symptomatic Relief
- Meclizine: FDA-approved for vertigo associated with vestibular system diseases
For Refractory Cases
Dopamine receptor antagonists may be considered:
- Prochlorperazine (5-10 mg PO TID)
- Metoclopramide (5-10 mg PO QID)
- Haloperidol (0.5-2 mg PO daily-BID)
- Olanzapine (2.5-5 mg PO daily) 1
For anxiety-related dizziness: Lorazepam (0.5-1 mg q4h PRN) 1
Vestibular Rehabilitation
- Self-administered or clinician-guided therapy
- Particularly beneficial for elderly patients
- May decrease recurrence rates 1
- Should be considered as complementary to CRPs
Special Considerations
Treatment Challenges
- Post-treatment down-beating nystagmus and vertigo ("otolithic crisis") occurs in approximately 19% of patients after Epley maneuver 5
- Absence of nystagmus during treatment does not indicate treatment failure 5
- Patients with mobility issues may require modified techniques 1
Surgical Options
- Surgical canal plugging should be considered only for selected cases of intractable, severe, same-canal, same-side BPPV 3
- Reserved for patients who fail multiple attempts at repositioning maneuvers
Follow-up and Patient Education
- Patients should be reassessed within 1 month after initial treatment 1
- Advise patients about increased fall risk, especially the elderly
- Educate about possible recurrence and recognition signs
- Recommend lifestyle modifications including regular physical activity 1
Common Pitfalls to Avoid
- Relying on medications as primary treatment instead of CRPs
- Ordering unnecessary imaging studies
- Overlooking multiple canal involvement
- Inadequate follow-up
- Failing to recognize post-treatment "otolithic crisis" which could lead to falls 5
Treatment Algorithm
- Confirm diagnosis with appropriate positioning tests
- Identify canal involvement (posterior, horizontal, or anterior)
- Perform appropriate CRP based on canal involvement (1-3 attempts)
- Consider vestibular rehabilitation for all patients
- Use medications only for symptomatic relief if necessary
- Schedule follow-up within one month
- Consider surgical options only for truly refractory cases
