Acute otitis media--a structured approach.

BACKGROUND

Two-thirds of all children have an episode of acute otitis media (AOM) before their third birthday. Antibiotic treatment is often given immediately, even though adequate scientific evidence for this practice is lacking.

METHOD: This review is based on a selective literature search including previously published evidence-based recommendations, particularly those of the current American guidelines.

RESULTS

A purulent tympanic effusion, possibly associated with inflammation of the tympanic membrane, is indicative of AOM. Only some patients with AOM need immediate antibiotic treatment: children with severe otalgia and/or fever of 39.0°C or above, infants under 6 months of age, and children with certain specific risk factors, including immune deficiency and Down syndrome. In other cases, symptomatic treatment is appropriate. Antibiotic therapy (preferably with amoxicillin) should be initiated only if the symptoms and signs do not improve within two to three days.

CONCLUSION

As the currently available data are not fully consistent, there is still a need for controlled trials with well-defined endpoints to determine the relative benefits of immediate antibiotic treatment versus two to three days of watchful waiting.
