Acute Otitis Media (AOM) in Pediatrics: Diagnosis and Management

Medically Reviewed by Dr. M. Salar Raza | Official SCFHS 2026 Blueprint

Clinical Pathway

Acute Otitis Media (AOM) is characterized by acute onset of symptoms (fever, ear pain) and signs of middle ear inflammation, such as a bulging tympanic membrane. The first-line antibiotic therapy for AOM is Amoxicillin, given at a high dose (80-90 mg/kg/day). Amoxicillin is effective against the most common bacterial pathogen, Streptococcus pneumoniae. If the patient has been treated with amoxicillin in the past 30 days, or has concurrent purulent conjunctivitis, Amoxicillin-clavulanate is preferred to cover beta-lactamase-producing organisms like H. influenzae.

Clinical Reasoning

The clinical presentation of fever, ear pain, and a bulging tympanic membrane strongly suggests Acute Otitis Media (AOM). The bulging TM is the hallmark sign differentiating AOM from otitis media with effusion. High-dose Amoxicillin is the standard first-line treatment as it adequately targets susceptible and intermediate-resistant strains of Streptococcus pneumoniae, the most common etiology. Alternatives like Azithromycin or Cefdinir are considered in patients with penicillin allergies, while Amoxicillin-clavulanate is reserved for specific cases where beta-lactamase producers are suspected.

Sample MCQ

A 6-year-old boy presents with a 2-day history of right ear pain and fever. Examination reveals a bulging, erythematous right tympanic membrane with absent light reflex. What is the most appropriate first-line treatment?

  • AAzithromycin
  • BAmoxicillin
  • CCefdinir
  • DObservation only

Correct Answer: Amoxicillin

The clinical presentation is classic for Acute Otitis Media (AOM). The first-line antibiotic treatment for AOM in children, in the absence of penicillin allergy or recent amoxicillin use, is high-dose Amoxicillin. It targets the most common bacterial causes, particularly Streptococcus pneumoniae.
