Most children have routinely been treated with antimicrobial drugs in the US. A watchful-waiting strategy has long been applied in several countries to minimize the use of antimicrobial drugs. -Netherlands and Scotland4,5 -USA,2004,6,7 -Canada 8 AOM in children aged 6 to 23 months is “nonsevere” 6(mild otalgia and T≤ 39℃ during the preceding 24 hours) Diagnosis of AOM is uncertain.7 The watchful waiting strategy has been based on the results of clinical trials3 that showed relatively high rates of spontaneous improvement in children with acute otitis media. Limitations of earlier trials : -The lack of stringent diagnostic criteria; -The inclusion of few very young children; -Antimicrobial drug had limited efficacy or was administered in suboptimal doses.9 Rates of spontaneous improvement similar to the rates seen in those studies among children receiving placebo have not been found uniformly.6 Therefore, for children with AOM, the circumstances in which immediate antimicrobial treatment is the preferred strategy have remained unclear. OBJECTIVES To evaluate the extent to which antimicrobial treatment(Amoxicillin-clavulanate) and placebo treatment affect the course of both symptoms and signs of AOM in children aged 6 to 23 months .
