Acute otitis media is infection of the middle ear by a bacteria and/or virus. Acute otitis media can occur as a result of a cold, sore throat or respiratory infection.
While any child may develop an ear infection, the following are some of the factors that may increase your child's risk of developing ear infections:
Middle ear infections are usually a result of poor function of the eustachian tube, the canal that links the middle ear with the throat area. The eustachian tube helps to equalize the pressure between the air around you and the middle ear.
When this tube is not working properly, it prevents normal drainage of fluid from the middle ear, causing a build up of fluid behind the eardrum. When this fluid cannot drain, it allows for the growth of bacteria and viruses in the ear that can lead to acute otitis media.
The following are some of the reasons that the eustachian tube may not work properly:
The following are the most common symptoms of otitis media. However, each child may experience symptoms differently. Symptoms may include:
The symptoms of acute otitis media may resemble other conditions or medical problems. Always see your child's physician for a diagnosis.
In addition to a complete medical history and physical examination, your child's physician will inspect the outer ear(s) and eardrum(s) using an otoscope. The otoscope is a lighted instrument that allows the physician to see inside the ear. A pneumatic otoscope blows a puff of air into the ear to test eardrum movement.
A hearing test may be obtained in children who have frequent ear infections.
The specific treatment for this condition depends on many factors and is tailored for each child. Please discuss your child's condition, treatment options and your preferences with your child's physician or healthcare provider.
Treatment may include:
If your child continues to have frequent ear infections, your child's physician may suggest that ear tubes (myringotomy tubes) be placed in the ear(s). This surgical procedure, called myringotomy, involves making a small opening in the eardrum to drain the fluid and relieve the pressure from the middle ear. A small tube is placed in the opening of the eardrum to allow air to enter (ventilate) the middle ear and to prevent fluid from accumulating. The child's hearing is restored after the fluid is drained. The tubes usually fall out on their own after six to twelve months.
Your child's surgeon may also recommend the removal of the adenoids (lymph tissue located in the space above the soft roof of the mouth, also called the nasopharynx) if they are infected. Removal of the adenoids has been shown to help some children with acute otitis media.
Treatment will depend upon the type of otitis media. Consult your child's physician regarding treatment options.
In addition to the symptoms listed above, acute otitis media can also result in any or all of the following:
