📌 INTRODUCTION

Benign Paroxysmal Positional Vertigo (BPPV) is the most frequent peripheral vestibular disorder. It is caused by displaced otoconia (canaliths) migrating into the posterior semicircular canal, generating abnormal endolymph flow and positional vertigo.

👉 The Epley maneuver is a canalith repositioning procedure (CRP) designed to return these particles to the utricle.

---

🧪 DIAGNOSTIC BASIS

🔍

• Gold standard for posterior canal BPPV
• Positive when:
  • Latency (2–5 sec)
  • Transient vertigo
  • Torsional/upbeating nystagmus toward affected ear

👉 Confirms posterior canal involvement

---

🔄 EPLEY MANEUVER – STEP BY STEP (CLINICAL PRECISION)

🟢 STEP 1 — INITIAL POSITION

• Patient seated
• Head rotated 45° toward affected side

---

🟡 STEP 2 — SUPINE EXTENSION

• Rapid transition to supine
• Neck extended ~20° below horizontal
• Maintain 30–60 seconds

👉 Observe nystagmus/vertigo

---

🔵 STEP 3 — CONTRALATERAL ROTATION

• Rotate head 90° toward opposite side
• Maintain extension
• Hold 30–60 seconds

---

🟣 STEP 4 — LATERAL DECUBITUS

• Roll patient onto side (nose downward)
• Additional 90° head rotation
• Hold 30–60 seconds

---

⚫ STEP 5 — RETURN TO SITTING

• Slow return to upright position
• Head returns to neutral

---

🧠 PATHOPHYSIOLOGICAL BASIS

The maneuver uses gravity-dependent repositioning:

• Moves otoconia along posterior canal
• Returns particles to utricle
• Eliminates abnormal vestibular stimulation

---

📊 EFFECTIVENESS (2026 EVIDENCE)

• ✅ 70–80% resolution after 1 session
• ✅ 90–95% after 2–3 sessions
• High-level evidence in:
  • guidelines
  • Cochrane reviews

---

⚠️ POST-PROCEDURE RECOMMENDATIONS

• Avoid lying flat 24–48 h
• Sleep semi-upright
• Avoid affected side for ~1 week
• Limit abrupt head movements (24 h)

📌 (Note: some modern protocols are less restrictive, but still widely applied)

---

🚨 CLINICAL ERRORS (CRITICAL)

❌ Incorrect side identification
❌ Insufficient head extension
❌ Not holding positions long enough
❌ Ignoring central causes of vertigo

---

🧠 DIFFERENTIAL DIAGNOSIS (RED FLAGS)

Suspect central vertigo if:

• No latency
• Persistent nystagmus
• Neurological deficits
• Severe headache

👉 Requires urgent neuro evaluation

---

🏥 OPERATIONAL INTEGRATION (EMS / PRIMARY CARE)

• Rapid bedside diagnosis
• Immediate treatment possible
• Avoids unnecessary imaging
• High cost-effectiveness

---

🔥 FINAL MESSAGE

BPPV is mechanical…
and must be treated mechanically.

👉 The Epley maneuver is not optional —
it is first-line definitive treatment.
