Acute otitis media (AOM) in young children consumes a substantial amou
nt of medical care services provided by primary-care physicians. A rec
ent increase in the number of young children with AOM prompted a revie
w of the associated risk factors, Eustachian tube dysfunction, bacteri
al colonization, and host inflammatory response form the basis for the
development of AOM, Signs and symptoms of AOM in young children are o
ften nonspecific and subtle, particularly in infants. Physical examina
tion and pneumatic otoscopy verify the diagnosis. New modalities inclu
ding tympanometry and acoustic reflectometry may be helpful, Amoxicill
in remains the drug of choice for AOM, despite recent trends in microb
ial resistance. Second- and third-line antimicrobial agents might be c
onsidered in selected clinical settings. Young children with recurrent
episodes of otitis media must be monitored closely. Preventive measur
es and medical or surgical intervention should be considered in order
to minimize the long-term medical and developmental effects of AOM.
