Overview

Acute otitis media (AOM) usually follows a viral upper respiratory tract infection leading to Eustachian tube dysfunction with impaired clearance and pressure regulation of the middle ear. Current guidelines recommend observation for children age 6 to 24 months with unilateral AOM without otorrhea or children older than 2 years with unilateral or bilateral AOM without otorrhea. Antibiotics covering common bacterial pathogens (e.g., Streptococcus pneumoniae, Moraxella catarrhalis, and non-typeable Haemophilus influenzae) have been used with success in selected patients to accelerate the recovery and lower the risk of tympanic membrane perforations and contralateral AOM episodes. High-dose amoxicillin (90 mg/kg/day) remains the drug of choice for initial antibiotic therapy; high-dose amoxicillin-clavulanate or intramuscular ceftriaxone should be reserved for patients who fail to respond to first-line treatment within 48 to 72 hours.

Medical Therapy

Initial management of uncomplicated AOM with high certainty of diagnosis

Clinical Practice Guideline from the American Academy of Pediatrics

Age	AOM With Otorrhea	AOM With Severe Symptoms†	Bilateral AOM Without Otorrhea	Unilateral AOM Without Otorrhea
6 mo to 2 y	Antibiotic therapy	Antibiotic therapy	Antibiotic therapy	Antibiotic therapy or additional observation
≥ 2 y	Antibiotic therapy	Antibiotic therapy	Antibiotic therapy or additional observation	Antibiotic therapy or additional observation

^† A toxic-appearing child, persistent otalgia more than 48 h, temperature ≥39°C (102.2°F) in the past 48 h, or if there is uncertain access to follow-up after the visit.

Observation

Due to the self-limited nature of most episodes of AOM (particularly in children 2 years and older), initial observation is advisable for selected patients if close follow-up can be ensured and rescue antibiotics administered for persistent or worsening symptoms in 48 to 72 hours.

Antibiotic Therapy

The rationale for antibiotic therapy in children with AOM is based on a high prevalence of bacteria from tympanocentesis cultures. A significant benefit of immediate antibiotic therapy is most evident in bilateral AOM, AOM with severe symptotms, AOM with otorrhea, or Streptococcus pneumoniae infection.

When a decision to treat with antibiotics has been made, high-dose amoxicillin is recommended if all of the following criteria are fulfilled:

• The patient has not received amoxicillin in the past 30 days.
• The patient does not have concurrent purulent conjunctivitis.
• The patient is not allergic to penicillin.

Additional β-lactamase coverage should be considered if any of the following criteria is fulfilled:

• The patient has received amoxicillin in the past 30 days.
• The patient has concurrent purulent conjunctivitis.
• The patient has a history of recurrent AOM unresponsive to amoxicillin.
