Middle Ear Infection
(Acute Otitis; Ear Infection, Middle; Otitis Media)
by Rosalyn Carson-DeWitt, MD
The middle ear is located behind the eardrum. An infection can enter this area and cause swelling and pain.
Most middle ear infections are caused by viruses. Others may be caused by a bacteria.
Most ear infections develop after a cold or flu. A tube called the eustachian tube runs from the middle ear to the back of the throat. If you have a cold or flu the infection can pass from the throat, through the tubes and up to the ears.
Risk Factors TOP
Middle ear infections are more common in infants and toddlers because their eustachian tubes are shorter. They occur more often during the winter months. Other factors that may increase your chance of a middle ear infection include:
A middle ear infection may cause:
The doctor will ask about symptoms and medical history. A physical exam will be done. Most middle ear infections can be diagnosed by looking into the ear with a lighted instrument called an otoscope.
The doctor will see if there is fluid or pus behind the eardrum. A small tube and bulb may be attached to the otoscope. This is to blow a light puff of air into the ear. The puff helps the doctor see if the eardrum is moving normally.
Other tests may include:
The doctor may choose to wait and see, since most ear infections will pass on their own within 2-3 days. During this time period, medications will not be prescribed. Infections that are severe, last longer than expected, or occur in children 6 months and under may need more treatment.
Medications may be used to help manage symptoms. Options include:
Antibiotics are not often needed. They are used for severe infections caused by bacteria. Mild infections caused by bacteria can pass on its own without antibiotics. Using antibiotics when not needed can actually make you more ill, than letting the infection pass on its own.
Note: Aspirin is not recommended for children with a current or recent viral infection. Check with your doctor before giving your child aspirin.
Note: Decongestants and antihistamines are not recommended to treat ear infections.
A myringotomy may be done to drain fluid from the inner ear. A tiny cut is made in the eardrum to drain fluid and pus. An ear tube may also be placed to let fluids continue to drain.
