Basic Understanding of the Ear System

The Ear system consists of the outer ear portion that leads from the outside through the ear canal, right up to the Ear drum. This path is lined by hair (cilia) that trap foreign particles and insects. Also, like the nasal path that secretes mucus, this canal also secretes wax to inhibit foreign particles from reaching the ear drum.

The ear system also has an inner portion leading from the ear drum and ending with the Eustachian tubes that open into the throat.

Now, because the ear drum is a curtain that separates the outer ear from the inner ear system, there must be a way that pressure is maintained in balance between the outer and inner ear, or else this would result in problems such as pressure build up, loss of hearing, dizziness and could even lead to related ear infections.
The way this pressure is maintained is through the openings of the ear in the throat which expose the inner ear to the same atmospheric pressure as the outer ear.
 

What is an ear infection?
An ear infection is an inflammation of the middle ear, usually caused by bacteria, that occurs when fluid builds up behind the eardrum. Anyone can get an ear infection, but children get them more often than adults. Three out of four children will have at least one ear infection by their third birthday. In fact, ear infections are the most common reason parents bring their child to a doctor. The scientific name for an ear infection is otitis media (OM).

What are the symptoms of an ear infection?
There are three main types of ear infections. Each has a different combination of symptoms.
Acute otitis media (AOM) is the most common ear infection. Parts of the middle ear are infected and swollen and fluid is trapped behind the eardrum. This causes pain in the ear—commonly called an earache. Your child might also have a fever.

.Otitis media with effusion (OME) sometimes happens after an ear infection has run its course and fluid stays trapped behind the eardrum. A child with OME may have no symptoms, but a doctor will be able to see the fluid behind the eardrum with a special instrument.

Chronic otitis media with effusion (COME) happens when fluid remains in the middle ear for a long time or returns over and over again, even though there is no infection. COME makes it harder for children to fight new infections and also can affect their hearing.

How can I tell if my child has an ear infection?
Most ear infections happen to children before they’ve learned how to talk. If your child isn’t old enough to say “My ear hurts,” here are a few things to look for:-
•Tugging or pulling at the ear(s)
•Fussiness and crying
•Trouble sleeping
•Fever (especially in infants and younger children)
•Fluid draining from the ear
•Clumsiness or problems with balance
•Trouble hearing or responding to quiet sounds

What causes an ear infection?
An ear infection usually is caused by bacteria and often begins after a child has a sore throat, cold, or other upper respiratory infection. If the upper respiratory infection is bacterial, these same bacteria may spread to the middle ear; if the upper respiratory infection is caused by a virus, such as a cold, bacteria may be drawn to the microbe-friendly environment and move into the middle ear as a secondary infection. Because of the infection, fluid builds up behind the eardrum.

The ear has three major parts: the outer ear, the middle ear, and the inner ear.
The outer ear, also called the pinna, includes everything we see on the outside—the curved flap of the ear leading down to the earlobe—but it also includes the ear canal, which begins at the opening to the ear and extends to the eardrum. The eardrum is a membrane that separates the outer ear from the middle ear.
The middle ear—which is where ear infections occur—is located between the eardrum and the inner ear. Within the middle ear are three tiny bones called the malleus, incus, and stapes that transmit sound vibrations from the eardrum to the inner ear. The bones of the middle ear are surrounded by air.
The inner ear contains the labyrinth, which help us keep our balance. The cochlea, a part of the labyrinth, is a snail-shaped organ that converts sound vibrations from the middle ear into electrical signals. The auditory nerve carries these signals from the cochlea to the brain.

Other nearby parts of the ear also can be involved in ear infections. The eustachian tube is a small passageway that connects the upper part of the throat to the middle ear. Its job is to supply fresh air to the middle ear, drain fluid, and keep air pressure at a steady level between the nose and the ear.

Adenoids are small pads of tissue located behind the back of the nose, above the throat, and near the eustachian tubes. Adenoids are mostly made up of immune system cells. They fight off infection by trapping bacteria that enter through the mouth.

Why are children more likely than adults to get ear infections?
There are several reasons why children are more likely than adults to get ear infections.
Eustachian tubes are smaller and more level in children than they are in adults. This makes it difficult for fluid to drain out of the ear, even under normal conditions. If the eustachian tubes are swollen or blocked with mucus due to a cold or other respiratory illness, fluid may not be able to drain.
A child’s immune system isn’t as effective as an adult’s because it’s still developing. This makes it harder for children to fight infections.
As part of the immune system, the adenoids respond to bacteria passing through the nose and mouth. Sometimes bacteria get trapped in the adenoids, causing a chronic infection that can then pass on to the eustachian tubes and the middle ear.

How is an acute middle ear infection treated?
Many doctors will prescribe an antibiotic, such as amoxicillin, to be taken over seven to 10 days. Your doctor also may recommend over-the-counter pain relievers such as acetaminophen or ibuprofen, or eardrops, to help with fever and pain. (Because aspirin is considered a major preventable risk factor for Reye’s syndrome, a child who has a fever or other flu-like symptoms should not be given aspirin unless instructed to by your doctor.)

If your doctor isn’t able to make a definite diagnosis of OM and your child doesn’t have severe ear pain or a fever, your doctor might ask you to wait a day to see if the earache goes away. Sometimes ear pain isn’t caused by infection, and some ear infections may get better without antibiotics. Using antibiotics cautiously and with good reason helps prevent the development of bacteria that become resistant to antibiotics.

If your doctor prescribes an antibiotic, it’s important to make sure your child takes it exactly as prescribed and for the full amount of time. Even though your child may seem better in a few days, the infection still hasn’t completely cleared from the ear. Stopping the medicine too soon could allow the infection to come back. It’s also important to return for your child’s follow-up visit, so that the doctor can check if the infection is gone.

How long will it take my child to get better?
Your child should start feeling better within a few days after visiting the doctor. If it’s been several days and your child still seems sick, call your doctor. Your child might need a different antibiotic. Once the infection clears, fluid may still remain in the middle ear but usually disappears within three to six weeks.

What happens if my child keeps getting ear infections?
To keep a middle ear infection from coming back, it helps to limit some of the factors that might put your child at risk, such as not being around people who smoke and not going to bed with a bottle. In spite of these precautions, some children may continue to have middle ear infections, sometimes as many as five or six a year. Your doctor may want to wait for several months to see if things get better on their own but, if the infections keep coming back and antibiotics aren’t helping, many doctors will recommend a surgical procedure that places a small ventilation tube in the eardrum to improve air flow and prevent fluid backup in the middle ear. The most commonly used tubes stay in place for six to nine months and require follow-up visits until they fall out.

If placement of the tubes still doesn’t prevent infections, a doctor may consider removing the adenoids to prevent infection from spreading to the eustachian tubes.

Can ear infections be prevented?
Currently, the best way to prevent ear infections is to reduce the risk factors associated with them. Here are some things you might want to do to lower your child’s risk for ear infections.
• Vaccinate your child against the flu. Make sure your child gets the influenza, or flu, vaccine every year.
• It is recommended that you vaccinate your child with the 13-valent pneumococcal conjugate vaccine (PCV13). The PCV13 protects against more types of infection-causing bacteria than the previous vaccine, the PCV7. If your child already has begun PCV7 vaccination, consult your physician about how to transition to PCV13. The Centers for Disease Control and Prevention (CDC) recommends that children under age 2 be vaccinated, starting at 2 months of age. Studies have shown that vaccinated children get far fewer ear infections than children who aren’t vaccinated. The vaccine is strongly recommended for children in daycare.
• Wash hands frequently. Washing hands prevents the spread of germs and can help keep your child from catching a cold or the flu.
• Avoid exposing your baby to cigarette smoke. Studies have shown that babies who are around smokers have more ear infections.
• Never put your baby down for a nap, or for the night, with a bottle.
• Don’t allow sick children to spend time together. As much as possible, limit your child’s exposure to other children when your child or your child’s playmates are sick.

Ear Infection Home Remedy
When used as a complimentary medicine along with the medication suggested by the doctor, inner ear infection remedies are very useful. Using some natural medication and herbs like chamomile and colloidal silver can prevent the ear infection as well as pain caused due to ear infection. Glycerin nasal spray, garlic oil, tea tree oil, clove oil and olive oil are very useful home remedies. It is often observed that mineral and vitamin deficiencies can cause ear problems, hence it is good to include enough sources of vitamin C, vitamin B3, vitamin B6 and vitamin B12 in the diet. Timely cleanup of the eardrums with clean ear buds may also prevent any sort of ear infection that can be caused due to its excess. It is also important to treat cold or flu infections as they might cause ear infection. It is also suggested by the doctors to chew limited amount of chewing gum, containing xylitol to protect the ear from getting infected.
