Anatomy & Body Systems
1. Vestibular System (Inner Ear)
- Semicircular Canals: Three canals (anterior/posterior/horizontal) detecting rotation
- Utricle: Houses otoconia, detects linear acceleration
- Saccule: Detects vertical linear acceleration
- Otoconia: Calcium carbonate crystals (balance "stones")
2. Balance Pathways
- Vestibular Nerve: Carries balance signals to brain
- Brainstem: Integrates balance information
- Cerebellum: Coordinates balance and movement
The vestibular system works like a gyroscope. The three semicircular canals are oriented at right angles to each other, each detecting rotation in one plane. When you move your head, the fluid inside the canals moves, and hair cells detect this movement, sending signals to the brain about head position and movement.
In BPPV, otoconia crystals become displaced into a semicircular canal. When the head changes position, gravity pulls these crystals, causing them to move within the canal and inappropriately stimulate the hair cells. This sends incorrect signals about movement, causing the intense spinning sensation.
Otoconia are calcium carbonate crystals that form on the otolithic membrane in the utricle. They are embedded in a gelatinous matrix and weighted, allowing them to detect gravity and linear acceleration. With age or trauma, these crystals can break loose and migrate into the semicircular canals.
Types & Classifications
| Canal | Percentage | Characteristics |
|---|---|---|
| Posterior | 85-95% | Most common, treated with Epley |
| Horizontal | 5-15% | Supine roll test, BBQ roll treatment |
| Anterior | Rare | Often from trauma |
| Type | Mechanism | Treatment Response |
|---|---|---|
| Canalithiasis | Free-floating crystals | Excellent to repositioning |
| Cupulolithiasis | Crystals attached to cupula | More resistant to treatment |
| Type | Description |
|---|---|
| Idiopathic | No identifiable cause (50-70%) |
| Secondary | Head trauma, Meniere's, vestibular neuritis, surgery |
Causes & Root Factors
1. Idiopathic (Unknown) Most BPPV has no identifiable cause. Age-related degenerative changes in the utricle may contribute to crystal displacement.
2. Head Trauma Head injury is the most common known cause. Trauma can dislodge otoconia from the utricle. BPPV may develop immediately or weeks after injury.
3. Inner Ear Disorders
- Meniere's disease
- Vestibular neuritis
- Labyrinthitis
- Previous ear surgery
4. Degenerative Changes
- Age-related wear and tear
- Osteoporosis (calcium metabolism changes)
- Prolonged bed rest
- Position during sleep
- Dental procedures (head positioned back)
- Migraine may increase susceptibility
Risk Factors
- Age: Risk increases after 40, peaks 60-70
- Sex: Women 2x more likely than men
- Occupation: May be higher in some professions
- Previous head injury
- History of vestibular disorders
- Osteoporosis
- Inactivity/prolonged bed rest
- Poor sleep position
Signs & Characteristics
Primary Signs:
- Intense vertigo (spinning) lasting 10-30 seconds
- Triggered by specific head movements:
- Getting in/out of bed
- Looking up
- Rolling over in bed
- Bending forward
- Nausea (often intense, but vomiting uncommon)
- Vertigo fatigues with repeated position changes
Secondary Signs:
- Blurred vision during episodes
- Unsteadiness (between episodes)
- Anxiety about head movements
- Guarded head movements
The classic pattern is intense vertigo with position change, lasting seconds, then resolving until the next position change. Patients often describe:
- "The room spins when I lie down"
- "I can't turn over in bed without the room spinning"
- "Looking up makes me dizzy"
The vertigo is rotational (spinning), not just lightheadedness. Nausea typically accompanies the spinning but usually doesn't progress to vomiting.
- Onset: Sudden, often noticed first thing in morning
- Duration: Seconds per episode
- Frequency: Variable, may occur multiple times per day
- Pattern: Often improves over weeks, may recur
Associated Symptoms
| Symptom | Connection | Frequency |
|---|---|---|
| Nausea | Vestibular stimulation | 70-80% |
| Blurred Vision | Eye movement during vertigo | 50% |
| Imbalance | Between episodes | 30-40% |
| Anxiety | Fear of movement | Common |
Cluster 1: Classic BPPV Brief vertigo + specific triggers + no hearing loss = Typical BPPV
Cluster 2: Central Vertigo Persistent vertigo + neurological symptoms = Needs full evaluation
Clinical Assessment
1. Symptom Description
- What does the dizziness feel like? (spinning vs. lightheaded)
- How long does each episode last?
- What triggers it?
- Any nausea?
- Any hearing changes?
2. Medical History
- Recent head injury?
- Previous vertigo episodes?
- Inner ear problems?
- Migraines?
3. Medication Review
- Ear drops
- Aminoglycoside antibiotics (ototoxic)
- Blood pressure medications
Dix-Hallpike Test The definitive diagnostic maneuver for posterior canal BPPV:
- Patient sits on exam table
- Head turned 45 degrees to one side
- Patient lies back quickly
- Observe for vertigo and nystagmus (eye jerking)
- Positive test = characteristic vertigo + nystagmus
Supine Roll Test For horizontal canal BPPV:
- Patient lies flat
- Head turned rapidly to each side
- Observes for vertigo and nystagmus
Diagnostics
Clinical Tests
The diagnosis is primarily clinical based on history and Dix-Hallpike maneuver. No imaging is typically needed.
MRI : Not routinely needed, but may be ordered if:
- Atypical features
- Concern for central cause
- Unilateral symptoms with hearing loss
Differential Diagnosis
| Condition | Distinguishing Features |
|---|---|
| Vestibular Neuritis | Prolonged vertigo (days), no position trigger |
| Meniere's | Hearing loss, tinnitus, longer episodes |
| Central Vertigo | Persistent symptoms, neurological signs |
| Orthostatic Hypotension | Lightheadedness on standing |
Conventional Treatments
1. Epley Maneuver (Canalith Repositioning) The primary treatment for posterior canal BPPV:
- Patient seated
- Head turned to affected side
- Patient lies back (triggers vertigo)
- Head turned to opposite side
- Patient rolls to side, head turned down
- Patient sits up
The maneuver moves crystals out of the canal into the uticle where they reabsorb. Success rate >80% with single treatment.
2. Semont Liberatory Maneuver Alternative for posterior canal BPPV
3. BBQ Roll / Lempert Maneuver For horizontal canal BPPV
Medications are generally NOT recommended for BPPV:
- No medication treats the underlying cause
- May prolong recovery
- Can cause sedation and increase fall risk
Rarely needed (<1%):
- Singular neurectomy
- Posterior semicircular canal occlusion

- Manage any inner ear conditions promptly
- Stay physically active
Secondary Prevention
After BPPV resolves:
- Continue balance exercises
- Sleep with head elevated initially
- Move deliberately when changing positions
- Be patient - recurrence is common

- 80-90% respond to single Epley maneuver
- Most resolve within weeks
- May recur (50% within 5 years)
- Quality of life excellent with treatment
Factors Affecting Outcome
Positive:
- Rapid diagnosis and treatment
- Proper repositioning technique
Negative:
- Delayed presentation
- Multiple canals affected

FAQ
Q: Can BPPV go away on its own? A: Yes, BPPV often resolves spontaneously within weeks to months. However, treatment accelerates resolution and provides immediate relief.
Q: Is BPPV dangerous? A: BPPV itself is benign (not dangerous), but the falls it can cause are dangerous. Treatment prevents falls.
Q: Can BPPV come back after treatment? A: Yes, recurrence is common (about 50% within 5 years). However, it can be easily treated again.
Q: Can I do the Epley maneuver at home? A: While home Epley is possible, proper diagnosis is essential first. Other conditions can mimic BPPV.
Q: Why do I feel dizzy even after the crystals are repositioned? A: Some residual sensitivity is common. Balance exercises and time help. Complete resolution may take days.
