Consider tympanocentesis and bacterial culture for children with recurrent or chronic disease.TreatmentPain and fever control are the most important interventions.Within 24 hours, 61% of patients have resolution of symptoms without antibiotics.Antibiotics (see table below) often do not change the duration of illness of AOM. ++Table Graphic Jump Location|Download (.pdf)|PrintAgeDiagnosis of AOM is CertainDiagnosis of AOM is Uncertain<6 moStart antibiotic treatmentStart antibiotic treatment6–24 moStart antibiotic treatmentObserve with follow-up assured if the patient's condition is non-severe (temperature <39°C [102.2°F] and mild otalgia);Start antibiotics if the patient's condition is severe (moderate to severe otalgia and temperature >39°C)≥24 moObserve with follow-up assured if the patient's condition is non-severe (temperature <39°C [102.2°F] and mild otalgia);Start antibiotics if the patient's condition is severe (moderate to severe otalgia and temperature >39°C)Observe with follow-up assured ++Table Graphic Jump Location|Download (.pdf)|PrintTemperature >39°C (102.2°F)Initial antibiotic choiceTreatment failure at 48–72 h after initial managementNoAmoxicillin, 80–90 mg/kg/day(If penicillin allergic: Non–type I: cefdinir, cefuroxime, or cefpodoxime; type I: azithromycin, clarithromycin)Amoxicillin–clavulanate, 90 mg/kg/day of amoxicillin with 6.4 mg/kg/ day of clavulanate(If penicillin allergic: Non–type I: ceftriaxone for 3 days; type I: clindamycin)YesAmoxicillin–clavulanate, 90 mg/kg/day of amoxicillin with 6.4 mg/kg/day of clavulanate(If penicillin allergic, ceftriaxone for 3 days)Ceftriaxone for 3 days(If penicillin allergic, tympanocentesis, clindamycin)++ Single high-dose azithromycin (30 mg/kg/dose) is equal to amoxicillin in efficacy (PIDJ 2005;24:153). Add topical agents as well for AOM with perforation or if the patient has tympanostomy tubes (eg, Ciprofloxacin; Ofloxacin).Surgical treatment: Consider ENT referral if the patient has >3 episodes in 6 mo or >4 episodes in 1 yr.Complications: Labyrinthitis, mastoiditis, intracranial extension, conductive hearing loss. ++ Epidemiology: Highest incidence <2 yo; 80% of <10 yo have had one episode of omePathophysiology: Eustachian tube dysfunction: Resolution of AOM → OME (45% at 1 mo after and 10% at 3 mo after AOM); GER; anatomic (children with cleft palate)Etiologic agents: Viruses > H. influenzae > Moraxella spp., bottle feeding, feeding supine, daycare attendance, allergies, smoke exposureDiagnosisOften OME is subjectively asymptomatic → no intervention ...
