Canalith Repositioning
Canalith repositioning procedures (CRP) are specific movements designed to relocate displaced calcium crystals within the inner ear, providing rapid relief from BPPV symptoms.
How It Works
The Problem
- Calcium crystals (otoconia) become dislodged
- Float in semicircular canals
- Trigger false movement signals
- Cause vertigo with head movements
The Solution
- Guided head movements
- Use gravity to move crystals
- Return crystals to utricle
- Immediate symptom relief
Types of Maneuvers
Epley Maneuver
For posterior canal BPPV:
- Most common technique
- 80% success first treatment
- Series of 5 positions
- Takes 5-10 minutes
Semont Maneuver
Alternative for posterior canal:
- Rapid movement technique
- Side-lying positions
- Effective alternative
- Patient preference
Barbecue Roll
For horizontal canal BPPV:
- 360-degree rotation
- Multiple position changes
- Effective for lateral canal
- May need repetition
Gufoni Maneuver
For horizontal canal:
- Side-lying technique
- Quick position changes
- Good success rate
- Less movement required
Treatment Process
Assessment
- Dix-Hallpike test
- Roll test
- Identify affected canal
- Determine crystal location
Procedure
- Explain process
- Position patient appropriately
- Guide through movements
- Monitor for nystagmus
Post-Treatment
- Brief rest period
- Home instructions
- Activity guidelines
- Follow-up plan
Success Rates
Immediate Relief
- 80% after first treatment
- 95% within 3 treatments
- Rapid symptom resolution
- Lasting results
Factors Affecting Success
- Correct diagnosis
- Proper technique
- Canal involved
- Patient compliance
After Treatment
First 48 Hours
- Sleep elevated (optional)
- Avoid rapid head movements
- Normal activities OK
- Some residual imbalance normal
Home Exercises
- Brandt-Daroff exercises
- Self-treatment techniques
- Prevention strategies
- When to return
Why Professional Treatment
Accurate Diagnosis
- Multiple types of BPPV
- Different canals affected
- Rule out other causes
- Proper testing
Expert Technique
- Precise positioning
- Appropriate speed
- Monitor response
- Modify as needed
Technology Assisted
- Vesticam visualization
- Track eye movements
- Confirm resolution
- Document progress
Recurrence Management
Prevention
- No specific prevention proven
- Maintain general health
- Treat quickly if returns
- Self-treatment education
Recurrence Rates
- 15-20% within one year
- 50% lifetime recurrence
- Quick treatment effective
- Not progressive condition
Special Considerations
Neck Problems
- Modified techniques available
- Gentle approaches
- Alternative positions
- Still effective
Elderly Patients
- Slower movements
- Extra support
- Fall prevention
- Excellent outcomes
When Not Appropriate
- Central vertigo
- Severe neck problems
- Recent neck/head trauma
- Unstable cardiac conditions
Requires medical review first.
