I now have enough to provide a thorough, well-structured answer. Let me compile it.
Otitis Media (AOM) - Treatment & Management
Diagnosis Criteria
AOM requires all three of the following:
- Acute onset of symptoms (ear pain, fever, irritability)
- Middle ear effusion (MEE) - confirmed by bulging/erythematous TM, air-fluid level, absent TM mobility on pneumatic otoscopy, or flat tympanogram
- Signs of middle ear inflammation (moderate-to-severe bulging of TM, new otorrhea not due to otitis externa)
A red but non-bulging TM without MEE = myringitis/tympanitis, not AOM. Ear pain with a normal, flaccid TM suggests a referred cause (dental abscess, TMJ disorder, pharyngitis, cervical arthritis, sinus infection).
Treatment Decision: Antibiotics vs. Observation
Immediate antibiotic therapy is indicated for:
- All infants < 6 months
- Children 6 months-2 years with bilateral AOM
- Any age with severe illness: moderate-severe otalgia OR temp > 39°C (102.2°F)
- Any age with AOM with otorrhea
Observation (watchful waiting, 2-3 days) is acceptable for:
- Children 6 months - 2 years with unilateral, non-severe AOM
- Children > 2 years with non-severe illness, if reliable follow-up is assured
- Not validated in adults - treat adults with antibiotics
Antibiotic Regimens
| Patient Group | First-Line Drug | Dose & Duration |
|---|---|---|
| Low-risk (> 6 yr, no recent antibiotics, no daycare, temp < 38°C) | Amoxicillin | 40-50 mg/kg/day divided doses x 5 days |
| High-risk (< 2 yr, daycare, recent antibiotics, otorrhea, temp > 38°C) | Amoxicillin | 80-90 mg/kg/day divided doses x 10 days |
| Treatment failure (symptoms persist after 3 days) | Amoxicillin-clavulanate (Augmentin) | 80-90 mg/kg/day x 7-10 days |
| Treatment failure alternative | Cefuroxime axetil | 20-30 mg/kg/day BID x 7-10 days |
| Treatment failure (severe/parenteral) | Ceftriaxone (IM/IV) | 50 mg/kg x 1-3 days |
| Penicillin allergy (non-severe) | Cefuroxime axetil or Cefpodoxime | Age-based dosing |
| Penicillin allergy (severe) | Ceftriaxone | See above |
Why high-dose amoxicillin? S. pneumoniae resistance to penicillin (15-50%) is mediated by altered penicillin-binding proteins - overcome by high-dose amoxicillin. H. influenzae and M. catarrhalis use beta-lactamase, which is why amoxicillin-clavulanate is used for treatment failures.
Pain Management
Antibiotics do not provide pain relief in the first 24 hours. Treat pain promptly with:
- Acetaminophen or ibuprofen (OTC analgesics) - first-line
- Topical anesthetic ear drops (short-term, if TM is intact)
Special Scenarios
AOM with perforation/otorrhea from acute perforation:
- Treat the same as AOM without perforation
- Most perforations are small and heal spontaneously
- Keep ear dry
Tympanostomy tube + acute otorrhea:
- Use ototopical fluoroquinolone drops (e.g., ciprofloxacin/ofloxacin drops)
- Avoid aminoglycoside ear drops - ototoxic if TM is not intact
Recurrent AOM (≥ 3 episodes/6 months or ≥ 4/year):
- Consider referral for tympanostomy tube insertion
- Prophylactic antibiotics are generally not recommended
Complications to Watch For
| Complication | Key Features | Management |
|---|---|---|
| Mastoiditis | Post-auricular erythema/tenderness, auricle protrusion, abnormal TM | CT scan if intracranial involvement suspected; IV antibiotics ± myringotomy; ENT referral |
| Meningitis / intracranial extension | Headache, stiff neck, altered mental status | Urgent CT + LP; hospitalization |
| Labyrinthitis | Vertigo + sensorineural hearing loss with AOM | ENT referral |
Key Organisms
- S. pneumoniae - 25-40% (most virulent; most likely to cause complications)
- H. influenzae - 10-30% (beta-lactamase producing strains respond to amoxicillin-clavulanate)
- M. catarrhalis - 2-15% (nearly all beta-lactamase producing)
