History
Epley’s manoeuver
Positional vertigo:
Inform the Patient
Inform the Patient
Day 1: vertical position - sleeping, head elevated
Normal activities afterward
Recurrence rate: 15% (Mobile otoliths)
Recurrence
Recurrence
Provoke vertigo in left -right decubitus (Identifies involved ear)
Repeat posterior canal manoeuvre (Patient himself)
Horizontal canal?: specific manoeuvre
Epley’s manoeuvre: FAILURE?
1) Wrong diagnosis
2) Wrong ear: cervical arthrosis
3) Wrong position: position “C”
4) Wrong “timing”: >1 1/2 min in each position
5) Wrong canal: horizontal canal? (other manoeuvre)

we can

WE!”CAN…!

RECOMMANDATIONS:
“Clinical practice guideline:
Benign paroxysmal positional vertigo”
Otolaryngology-Head and neck Surgery; November 2008: 139: S47-S81
1) BPV diagnoses is certain: BPV clinical history + Dix-Hall Pike (+)
2) “Clinicians should not obtain radiographic imaging, vestibular testing,
or either in a patient diagnosed with BPV.”
3) “Clinicians should not routinely treat BPV with vestibular suppressant
medications such as antihistamines or benzodiazepines.” (no Serc)
4) “Clinicians should treat patients with posterior canal BPV with particle
repositioning maneuver.” (Epley)
5) Clinicians should revaluate the patient one month after repositioning
maneuver.
Case 4
Male 51 years old
ER 14/09/02: Presented 2 “dizzy spells” in the morning while
attending a conference
Presents with episodes of sudden “fatigue” or “weakness”
lasting 5 minutes for 10 years. Frequency 4 to 6 a year.
Has been treated for “hypoglycemia”.
Does not drive his car outside Montreal, fearing a spell while driving!

Case 3
Woman 48 years old
First evaluation: 21-08-2001
“Dizzy spells”: 2 types
• Vertigo < 1 min changing position, with nausea - vomiting
• (Left lateral decubitus) - recurrent since a car accident in 1993
Dix Hallpike (+) left: Epley left ear
• Presyncope - syncope (Sudden onset - recovery). Began at age 16
always in standing position, more often with stimulus (dysmenorrhea
and sometimes with nausea induced by BPV)
Case 3
Woman 48 years old (continued)
Second evaluation: 12-12-2001
Severe disabling “dizzy spells”
• Weakness – Light headedness - " spins in the head "
• Concentration difficulty
• Palpitations - Shortness of breath - " Lasts all day " followed by intense
fatigue feeling
• Since 08/ 01 no “vertigo” while changing position - no syncope
Past history - Functional inquiry - Physical : NORMAL
Diagnosis: ???
Provoke patient’s hyperventilation
• Identification by the patient of the cause of his symptoms
• Explanation of “respiratory alcalosis”
• Recognition of stopping the symptoms by breath holding
• Elaboration of strategies for stress management
