Acute otitis media (AOM) may present with otalgia, irritability, decreased hearing, anorexia, vomiting, or fever, usually in the presence of an ongoing viral respiratory infection.
Physical examination will reveal a bulging, opacified tympanic membrane with an attenuated light reflex. The membrane may be white, yellow, pink, or red.
Diagnosis is generally made with conventional otoscopy.
Treatment includes pain control with analgesics and might include antibiotics.
Complications include otitis media with effusion, perforation of the tympanic membrane and, rarely, mastoiditis.
AOM) is an infection involving the middle ear space and is a common complication of viral respiratory illnesses. Although it may occur rarely in adults, AOM predominantly affects children and this will be the focus of this topic.
