Ear infections are common in young children resulting in millions of office visits and antibiotic prescriptions annually. Acute otitis media (AOM) includes intense signs and symptoms of infection and inflammation and is the most common bacterial illness in children for which antibacterial agents are prescribed in the United States. Otitis media with effusion (OME) is even more common.

An ear infection means that the middle ear is infected. The middle ear is the eardrum and the small space behind the eardrum. An ear infection is sometimes called 'acute otitis media'. A separate leaflet deals with infection of the ear canal (otitis externa).

Earaches are a common occurrence in our lives, especially with our children. Learn what causes them and how you can avoid them in the future.

Earaches can be anything from slightly painful to extremely painful and are usually brought on by a fluid buildup (sometimes resulting from an infection), or a buildup of pressure in the middle ear. A highly common cause of the earache is due to plugged 'Eustachian' tubes (the tube that comes from the back of your throat and connects to your middle ear). If and when your Eustachian tube becomes blocked, fluid will gather resulting in a painful earache, bringing with it the possibility of bacteria buildup or infection.

Ear pain can occur due to allergy, filling of wax in the ear, chillness, entry of any foreign body in the ear or infection in the Eustachian tube which connects ear, nose and throat.

Ear infections are the most common illnesses in babies and young children. Most often, the infection affects the middle ear and is called otitis media. The tubes inside the ears become clogged with fluid and mucus. This can affect hearing, because sound cannot get through all that fluid.

If a person has severe or persistent pain and fever, and the eardrum is bulging, a doctor may perform a myringotomy, in which an opening is made through the eardrum to allow fluid to drain from the middle ear.

The most common cause for temporary hearing loss is the fluid in the middle ear space associated with ear infections. On average, fluid lingers for 3 weeks following an ear infection, but it can remain for months.

The ear is responsible for hearing and balance and is made up of three parts - the outer ear, middle ear, and inner ear. Hearing begins when sound waves that travel through the air reach the outer ear, or pinna, which is the part of the ear you can see. The sound waves then travel from the pinna through the ear canal to the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles. When the eardrum vibrates, the ossicles amplify these vibrations and carry them to the inner ear.
