What is the recommended treatment for Benign Paroxysmal Positional Vertigo (BPPV) using Epley's maneuver?

Epley Maneuver for BPPV

The Epley maneuver is the first-line treatment for posterior canal BPPV with an 80-90% success rate after 1-3 treatments, and should be performed without medications or post-procedure restrictions. 1, 2

Treatment Efficacy and Evidence

The Epley maneuver (canalith repositioning procedure) demonstrates superior outcomes compared to all alternatives:

• Patients treated with the Epley maneuver are 6.5 times more likely to experience symptom improvement compared to controls (OR 6.52; 95% CI 4.17-10.20) 2
• Complete resolution of vertigo occurs in 56% of treated patients versus only 21% in controls at 1 week 3, 4
• A single Epley maneuver is more than 10 times more effective than a week of Brandt-Daroff exercises performed three times daily (OR 12.38; 95% CI 4.32-35.47) 2, 5
• Success rates reach 90.7% after the first maneuver and 96% after a second treatment 6
• Conversion from positive to negative Dix-Hallpike test occurs 9.6 times more often with Epley versus sham treatment (OR 9.62,95% CI 6.0 to 15.42) 3

Proper Technique

The Epley maneuver involves a specific sequence of head and body positions:

1. Patient sits upright with head turned 45° toward the affected ear 2
2. Rapidly lay patient back to supine head-hanging 20° position for 20-30 seconds 2, 5
3. Turn head 90° to the opposite side and hold for 20-30 seconds 2
4. Roll patient onto their side (nose pointing down) and hold for 20-30 seconds 2
5. Return patient to upright sitting position 2

Each position must be held for the full 20-30 seconds to allow otoconia to migrate through the semicircular canal back into the vestibule 5.

Critical Management Points

What NOT to Do

Do not prescribe vestibular suppressant medications (meclizine, antihistamines, benzodiazepines) as primary treatment for BPPV - they have no evidence of effectiveness and may interfere with central compensation mechanisms 1, 2. Studies show canalith repositioning maneuvers achieve 78.6%-93.3% improvement versus only 30.8% with medication alone 1.

Do not impose post-procedure restrictions - patients can resume normal activities immediately after the Epley maneuver, as restrictions provide no benefit and may cause unnecessary complications 2, 5.

Limited Medication Role

Vestibular suppressants may only be considered for:

• Short-term management of severe nausea/vomiting during the procedure 1
• Prophylaxis in patients who previously experienced severe nausea during repositioning 1
• Patients who refuse the maneuver entirely 1

However, patients who underwent Epley alone recovered faster than those receiving concurrent labyrinthine sedatives 1.

Managing Nausea During the Procedure

Approximately 12% of patients experience nausea or vomiting during the Epley maneuver 1:

• Counsel patients beforehand that they may experience intense vertigo lasting 30-60 seconds that will subside 1
• Move slowly between positions if the patient reports severe nausea 1
• Maintain each position for the full 20-30 seconds to allow symptoms to resolve before proceeding 1
• Consider the Semont maneuver as an alternative if the patient cannot tolerate Epley despite these modifications 1

Self-Treatment Options

After at least one properly performed in-office treatment, motivated patients can be taught self-administered Epley maneuvers 2, 5:

• Self-administered Epley achieves 64% improvement versus only 23% with Brandt-Daroff exercises 2, 5
• Patients must perform all 5 sequential steps, holding each position for 20-30 seconds 5
• This approach is significantly more effective than home Brandt-Daroff exercises 5

Treatment Failures and Reassessment

If symptoms persist after initial treatment 2:

• Repeat the Dix-Hallpike test to confirm persistent BPPV
• Perform additional Epley maneuvers - success rates reach 90-98% with repeat treatments 2
• Check for canal conversion (occurs in 6-7% of cases) where BPPV switches to a different canal 2, 5
• Evaluate for multiple canal involvement or bilateral BPPV 2
• Consider coexisting vestibular pathology if symptoms occur with general head movements or spontaneously 2
• Rule out central causes if atypical features are present 2

Reassess all patients within 1 month to document symptom resolution or persistence 1, 2.

Special Populations

Assess for contraindications before performing the maneuver 2:

• Severe cervical stenosis or radiculopathy
• Severe rheumatoid arthritis affecting the neck
• Spinal issues limiting mobility
• Impaired mobility or balance
• Increased fall risk (particularly in elderly patients)

For patients with physical limitations, consider vestibular rehabilitation therapy or referral to specialized vestibular physical therapy 2.

Common Pitfalls

• Failing to hold each position for the full 20-30 seconds reduces effectiveness 1, 5
• Moving the patient too slowly during transitions may allow otoconia to fall back 1
• Prescribing medications instead of performing the maneuver results in significantly worse outcomes 1, 2
• Not identifying the correct affected canal before treatment leads to treatment failure 2
• Imposing unnecessary post-procedure restrictions that have no evidence of benefit 2, 5

Alternative Maneuvers for Other Canal Variants

While the Epley maneuver treats posterior canal BPPV (85-95% of cases), other variants require different approaches 2:

• Horizontal canal BPPV (geotropic): Barbecue Roll (Lempert) maneuver or Gufoni maneuver 2
• Horizontal canal BPPV (apogeotropic): Modified Gufoni maneuver 2
• Semont maneuver: Alternative for posterior canal BPPV with comparable efficacy to Epley 1, 3

The number-needed-to-treat with the Epley maneuver is 3, making it one of the most effective interventions in vestibular medicine 4.
