✅ 1. Diagnosis of Acute Otitis Media (AOM)

Diagnostic Criteria — must have ALL:

A. Acute symptoms

  • Fever
  • Otalgia (ear pain)
  • Irritability in children
  • Otorrhea (only if TM perforation)

B. Middle-ear inflammation

Seen on otoscopy:

  • Bulging tympanic membrane (TM) — most specific finding
  • Erythema of TM
  • Reduced mobility on pneumatic otoscopy

C. Middle-ear effusion

  • Opaque TM
  • Air-fluid level
  • Loss of TM landmarks

👉 Bulging TM + acute ear pain = AOM until proven otherwise.


✅ 2. Diagnosis of Otitis Media with Effusion (OME)

OME = Fluid in middle ear WITHOUT signs of acute inflammation.

Diagnostic Features:

  • Hearing loss
  • A “fullness” sensation
  • TM retracted or neutral (NOT bulging)
  • Air-fluid level
  • Reduced TM mobility
  • NO fever, NO acute pain

OME is usually viral or allergic, not bacterial.

🩺 3. Management of Acute Otitis Media (AOM)

A. First-Line Antibiotic (if indicated)

Amoxicillin (80–90 mg/kg/day) divided BID for 5–10 days

  • Adults: Amoxicillin 500 mg TID × 5–7 days

When to treat with antibiotics?

Give antibioticsObserve
< 6 months≥ 2 years + mild symptoms
6–23 months with definite AOMUnilateral AOM, mild symptoms
Severe illness (fever ≥39°C, severe pain)Reliable follow-up

B. Second-Line Antibiotics

Use if:

  • Received amoxicillin in past 30 days
  • Concomitant purulent conjunctivitis
  • No improvement in 48–72h

→ Amoxicillin-Clavulanate (90 mg/kg/day) OR → Cefdinir / Cefpodoxime / Cefuroxime OR → IM Ceftriaxone (1–3 days)

C. Supportive Care

  • Ibuprofen or Acetaminophen
  • Warm compress
  • Adequate hydration

Avoid

❌ Decongestants ❌ Antihistamines ❌ Steroids They do not help in AOM (per AAP guidelines).


🩺 4. Management of Otitis Media With Effusion (OME)

Most important:

📌 OME does NOT require antibiotics 📌 OME does NOT require steroids 📌 Watchful waiting for 3 months is standard (AAP/AAO-HNS guidelines)

Management Plan

  1. Watchful waiting for 3 months
  2. Hearing assessment if:
    • OME persists >3 months
    • Speech delay
    • Developmental disorders
  3. Environmental modification
    • Avoid secondhand smoke
  4. Treat underlying allergy if present

Indications for Tympanostomy Tubes

  • Bilateral OME ≥ 3 months + documented hearing loss
  • Recurrent AOM:
    • ≥3 episodes in 6 months
    • OR ≥4 in 1 year (1 in past 6 months)

🧠 Quick Mnemonics

AOM diagnosis mnemonic — “BAR”

  • Bulging TM
  • Acute symptoms (pain, fever)
  • Reduced mobility

OME management mnemonic — “WHEAT”

  • Watchful waiting
  • Hearing test if >3 months
  • Evaluate for risk factors
  • Avoid unnecessary antibiotics
  • Tympanostomy tubes (if hearing issue >3 months)
