Treatment of Otitis Media
The treatment of otitis media should follow a stepwise approach with pain management as the primary initial intervention, followed by either watchful waiting or antibiotics depending on patient age, symptom severity, and type of otitis media.
Types of Otitis Media and Initial Approach
Acute Otitis Media (AOM)
- Pain management should be addressed immediately regardless of whether antibiotics are prescribed, as pain is the major symptom of AOM 1
- Accurate diagnosis is essential, with key diagnostic criteria including moderate to severe bulging of the tympanic membrane or new onset of otorrhea not due to acute otitis externa 1
Decision Algorithm for Antibiotic Treatment in AOM
Children:
Immediate antibiotics are indicated for:
Watchful waiting with option for delayed antibiotics is appropriate for:
Adults:
- Immediate antibiotic therapy for adults with severe symptoms (moderate to severe otalgia or fever) 4
- Observation with close follow-up for adults with mild symptoms 4
Antibiotic Selection
First-line Treatment:
- High-dose amoxicillin (80-90 mg/kg/day in children, 1.5-4 g/day in adults) divided into two doses is the first-line antibiotic for patients who have not received amoxicillin in the previous 30 days and do not have concurrent purulent conjunctivitis 2, 1, 5
- Amoxicillin is preferred due to its effectiveness against common pathogens, safety, low cost, and narrow microbiologic spectrum 4
Second-line Treatment:
- Amoxicillin-clavulanate should be used when:
Penicillin Allergy Alternatives:
- For non-type I hypersensitivity: cefdinir, cefpodoxime, or cefuroxime 1, 4
- For type I hypersensitivity: consider azithromycin, clarithromycin, or trimethoprim/sulfamethoxazole, though these have higher bacteriologic failure rates (20-25%) 4
Management of Treatment Failure
- If symptoms worsen or fail to improve within 48-72 hours of initial treatment, the patient should be reevaluated 1, 5
- For treatment failures on amoxicillin, switch to amoxicillin-clavulanate or another agent with coverage against beta-lactamase producing organisms 4
- Clinical trials have shown that delayed antibiotic initiation does not significantly worsen overall recovery from AOM, though it may be associated with prolonged resolution of some symptoms 6
Otitis Media with Effusion (OME)
- Watchful waiting is recommended initially for OME, with follow-up at 3 months and repeated hearing testing 2
- Medical treatment with antibiotics, decongestants, or nasal steroids is not recommended as they do not hasten the clearance of middle ear fluid 5
- Surgical intervention with tympanostomy tubes (TTs) should be considered for:
Prevention Strategies
- Reduce risk factors where possible:
- Immunization with pneumococcal conjugate vaccines and influenza vaccine is recommended 2, 1
- Xylitol has shown effectiveness in prevention but compliance may limit its applicability 7
Common Pitfalls and Caveats
- Overdiagnosis of AOM can lead to unnecessary antibiotic use; ensure proper visualization of the tympanic membrane and confirm signs of middle ear inflammation 4
- Long-term prophylactic antibiotics for recurrent AOM are discouraged by current guidelines 2
- Avoid widespread use of respiratory fluoroquinolones for milder disease as this may promote resistance 4
- Delayed antibiotic treatment may be associated with transient worsening of symptoms and potential economic impact due to parents missing work 6
