Epley Maneuver for Posterior Canal BPPV
The Epley maneuver (canalith repositioning procedure) is the most effective treatment to stop vertigo in adults with benign paroxysmal positional vertigo, achieving 80-93% symptom resolution after a single treatment and 90-98% success with repeat sessions if needed. 1, 2
Why the Epley Maneuver is First-Line Treatment
The American Academy of Otolaryngology-Head and Neck Surgery explicitly recommends canalith repositioning procedures—specifically the Epley maneuver—as definitive first-line treatment for posterior canal BPPV, which accounts for 85-95% of all BPPV cases. 1, 2 This recommendation is based on over 20 years of evidence including multiple randomized controlled trials and meta-analyses. 1
Patients treated with the Epley maneuver have 6.5 times greater chance of symptom improvement compared to controls (OR 6.52; 95% CI 4.17-10.20) and 9.6 times greater likelihood of converting from a positive to negative Dix-Hallpike test (OR 9.62; 95% CI 6.0-15.42). 1, 2
Importantly, a single Epley maneuver is more than 10 times more effective than a week of three-times-daily Brandt-Daroff exercises (OR 12.38; 95% CI 4.32-35.47). 1, 2
Step-by-Step Technique
The standardized Epley maneuver sequence involves: 1, 3
Starting position: Patient sits upright on examination table, head turned 45° toward the affected ear 1, 3
First position: Rapidly lay patient back to supine with head hanging 20° below horizontal, maintaining this position for 20-30 seconds 1, 3
Second position: Turn head 90° toward the unaffected side, hold for 20-30 seconds 1, 3
Third position: Turn head an additional 90° in the same direction while rolling the body from supine to lateral decubitus position (patient nearly face-down), hold for 20-30 seconds 1, 3
Final position: Bring patient to upright sitting position, completing the maneuver 1
Critical Execution Details
Movements between positions must be relatively rapid, particularly the transition from sitting to supine head-hanging position, to maintain effectiveness. 3 However, each position must be held for the full 20-30 seconds even if symptoms resolve earlier, allowing adequate time for otoconia migration through the semicircular canal. 3
Patients should be counseled beforehand that they may experience sudden intense vertigo, nausea, or a falling sensation during the procedure—these symptoms typically subside within 60 seconds and are expected responses. 1, 2
Expected Response Timeline
Most patients (70-80%) achieve complete resolution of vertigo within 24-48 hours after the first Epley maneuver. 3 By day 7, the Dix-Hallpike test converts to negative in 80.5% of patients treated with the Epley maneuver versus only 25% in those doing Brandt-Daroff exercises. 1
Post-Treatment Instructions
Patients can resume all normal activities immediately after the Epley maneuver—postprocedural restrictions (head elevation, sleeping position limitations, activity restrictions) provide no benefit and are NOT recommended. 1, 2, 3 This represents strong evidence-based guidance from the American Academy of Otolaryngology-Head and Neck Surgery. 2
When to Repeat the Maneuver
If symptoms persist at 1-2 week follow-up, repeat the Dix-Hallpike test to confirm persistent BPPV. 3 The maneuver can be repeated up to 3 times, with cumulative success rates reaching 90-98%. 1, 2, 3 After the second maneuver, recovery rates increase to 96%. 4
Treatment Failures: What to Consider
If symptoms persist after 2-3 properly performed Epley maneuvers: 2, 3
- Repeat diagnostic testing to confirm persistent posterior canal involvement
- Evaluate for canal conversion (occurs in 6-7% of cases), where posterior canal BPPV converts to lateral canal BPPV during treatment, requiring a different maneuver 1, 2
- Check for multiple canal involvement or bilateral BPPV
- Consider coexisting vestibular pathology if symptoms are provoked by general head movements or occur spontaneously
- Rule out central causes if atypical features are present (downward-beating nystagmus, severe neurological signs, lack of latency) 2
Alternative Maneuvers
The Semont (liberatory) maneuver is an equally effective alternative for posterior canal BPPV, with 94.2% resolution at 6-month follow-up and comparable efficacy to the Epley maneuver. 1, 2, 5 The choice between Epley and Semont is based on clinician preference, patient physical limitations, or failure of the previous maneuver. 6, 7
Contraindications and Special Populations
Exercise caution or consider modified approaches in patients with: 2, 3
- Severe cervical stenosis or radiculopathy
- Severe rheumatoid arthritis or ankylosing spondylitis affecting the cervical spine
- Significant vascular disease
- Severe kyphoscoliosis or limited cervical range of motion
- Morbid obesity
For these patients, consider Brandt-Daroff exercises or referral to specialized vestibular physical therapy. 2
What NOT to Do
Do NOT routinely prescribe vestibular suppressant medications (meclizine, antihistamines, benzodiazepines) for BPPV treatment. 1, 2, 8 There is no evidence these medications are effective as definitive treatment for BPPV, and they cause significant adverse effects including drowsiness, cognitive deficits, increased fall risk (especially in elderly patients), and interference with central compensation mechanisms. 1, 2, 8
Vestibular suppressants may only be considered for short-term management of severe nausea/vomiting in severely symptomatic patients or as prophylaxis 30-60 minutes before the maneuver in patients who previously experienced severe nausea during Dix-Hallpike testing. 1, 2
Recurrence Management
BPPV has inherently high recurrence rates: 10-18% at 1 year and 30-50% at 5 years. 2 Each recurrence should be treated with repeat Epley maneuver, which maintains the same high success rates of 90-98%. 2 Adding vestibular rehabilitation exercises after successful repositioning may reduce future recurrence rates by approximately 50%. 2
