Middle ear infections usually occur along with an
upper respiratory infection (URI), such as a cold.
builds up in the middle ear, creating a perfect breeding ground for bacteria or
viruses to grow into an ear infection.
Pus forms as the body
tries to fight the ear infection. More fluid collects and pushes against the
eardrum, causing pain and sometimes problems hearing. Fever typically lasts
a few days. And pain and crying usually last for several hours. After
that, most children have some pain on and off for several days, although young
children may have pain that comes and goes for more than a week.
Even newbie parents can spot diaper rash or a runny nose with no problem, but ear infections may come with only a whisper of symptoms. Yet three-quarters of children will get one by age 3.
"An ear infection happens when you get infected fluid or pus behind the eardrum," says Jennifer Shu, MD, FAAP. She is a pediatrician in Atlanta and editor of American Academy of Pediatrics Baby & Child Health. The most common cause? Colds. When secretions get trapped in the middle ear, viruses or bacteria...
Antibiotic treatment may shorten some
symptoms. But most of the time the
immune system can fight infection and heal the ear
infection without the use of these medicines.
In severe cases, too much fluid can increase pressure on the eardrum
ruptures, allowing the fluid to drain. When this
happens, fever and pain usually go away and the infection clears. The eardrum
usually heals on its own, often in just a couple of weeks.
complications, such as an ear infection with chronic drainage, can occur with
repeat ear infections.
Middle ear fluid buildup
Most children who have ear infections still have some fluid behind the
eardrum a few weeks after the infection is gone. For some children, the fluid
clears in about a month. And a few children still have fluid buildup (effusion) several
months after an ear infection clears. This fluid
buildup in the ear is called otitis media with effusion. Hearing problems can
result, because the fluid affects how the middle ear works. Usually, infection
does not occur.
Otitis media with fluid buildup (effusion) may occur even if a child
has not had an obvious ear infection or upper respiratory infection. In these
cases, something else has caused
eustachian tube blockage.
