Treatment of Benign Paroxysmal Positional Vertigo

Diagnosis and Classification

• The American Academy of Otolaryngology-Head and Neck Surgery recommends diagnosing BPPV when vertigo with characteristic nystagmus is provoked by the Dix-Hallpike maneuver or the supine roll test 2, 3
• The most common form of BPPV is posterior semicircular canal BPPV, followed by lateral canal BPPV 2, 4

First-Line Treatment

• The American Academy of Otolaryngology-Head and Neck Surgery recommends the Canalith Repositioning Procedure (Epley maneuver) as the treatment of choice for posterior canal BPPV, with success rates of 90-98% when performed correctly 1, 5
• The Epley maneuver involves a specific sequence of head positions, including:
• Alternative treatments for lateral canal BPPV include the Gufoni maneuver or barbecue roll maneuver, with success rates ranging from 86-100% 1, 2, 6

Important Clinical Considerations

• The American Academy of Otolaryngology-Head and Neck Surgery recommends against routinely prescribing vestibular suppressant medications for BPPV treatment, as they may be considered only for short-term management of severe nausea or vomiting 7, 3, 8, 9
• Postprocedural restrictions after repositioning maneuvers are not necessary 2
• Patients should be reassessed within 1 month after initial treatment to confirm symptom resolution 9, 7

Alternative or Adjunctive Treatments

• Vestibular rehabilitation exercises may be offered as an option, either self-administered or clinician-guided 6, 3
• Brandt-Daroff exercises are significantly less effective than CRP (25% vs 80.5% resolution at 7 days) but may be used in some cases 5

Management of Treatment Failures

• If symptoms persist after initial treatment, patients should be reevaluated for persistent BPPV, coexisting vestibular conditions, or central nervous system disorders mimicking BPPV 1, 4
• Canal conversion occurs in approximately 6% of cases and requires appropriate repositioning for the newly affected canal 1
• For cases refractory to multiple CRPs, surgical options like canal plugging may be considered, with success rates >96% 1

Common Pitfalls to Avoid

• Relying on medications instead of repositioning maneuvers is a common pitfall to avoid 7, 8
• Failing to reassess patients after initial treatment is another common pitfall to avoid 9
• Missing canal conversions or multiple canal involvement can also lead to treatment failure 1
