Ear infection..

Ear infections are often associated with children, but did you know that they can also affect adults? In fact, 20% of adults still experience ear infections. Bacteria and viruses don’t discriminate based on age.
It’s important for those with weak immune systems or ear inflammation to be vigilant and recognize the signs early for quick treatment. In this article, we’ll explore six crucial signs of an ear infection, as well as prevention tips to protect your hearing.
One of the initial signs of an ear infection is mild itchiness in the inner ear canal. If left untreated, this itchiness can worsen over time. If you find yourself frequently itching your ears, it may be worth consulting your doctor to rule out an infection. Remember, early detection is key to swift treatment and relief.

2. Redness

As an ear infection progresses, redness can begin to develop both inside and outside the ear. This redness is a clear sign of inflammation and should not be ignored. If you notice any unusual redness in or around your ears, it’s important to take it seriously and seek medical advice.
3. Discomfort or Pain

Ear pain is a common symptom of an ear infection, especially in the early stages. You may experience general discomfort or aching in your ear, particularly when manipulating the earlobe or tragus. As the infection progresses, you may also feel a sense of fullness in the ear. In some cases, the pain may even radiate to your face, neck, or head. Don’t ignore these signs of discomfort, as they may indicate an underlying infection that requires attention.

Overview

An ear infection (sometimes called acute otitis media) is an infection of the middle ear, the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. Children are more likely than adults to get ear infections.

Ear infection

In an ear infection, narrow tubes that run from the middle ear to high in the back of the throat (eustachian tubes) can become swollen and blocked. This can lead to mucus build-up in the middle ear. This mucus can become infected and cause ear infection symptoms.

Because ear infections often clear up on their own, treatment may begin with managing pain and monitoring the problem. Sometimes, antibiotics are used to clear the infection. Some people are prone to having multiple ear infections. This can cause hearing problems and other serious complications.

The onset of signs and symptoms of ear infection is usually rapid.

Children

Signs and symptoms common in children include:

Ear pain, especially when lying down
Tugging or pulling at an ear
Trouble sleeping
Crying more than usual
Fussiness
Trouble hearing or responding to sounds
Loss of balance
Fever of 100 F (38 C) or higher
Drainage of fluid from the ear
Headache
Loss of appetite

Adults

Common signs and symptoms in adults include:

Ear pain
Drainage of fluid from the ear
Trouble hearing

When to see a doctor

Signs and symptoms of an ear infection can indicate several conditions. It’s important to get an accurate diagnosis and prompt treatment. Call your child’s doctor if:

Symptoms last for more than a day
Symptoms are present in a child less than 6 months of age
Ear pain is severe
Your infant or toddler is sleepless or irritable after a cold or other upper respiratory infection
You observe a discharge of fluid, pus or bloody fluid from the ear

Causes

An ear infection is caused by a bacterium or virus in the middle ear. This infection often results from another illness — cold, flu or allergy — that causes congestion and swelling of the nasal passages, throat and eustachian tubes.

Middle ear

The middle ear has three small bones — the hammer, or malleus; the anvil, or incus; and the stirrup, or stapes. The eardrum keeps the bones away from the outer ear. A narrow path called the eustachian tube joins the middle ear to the back of the nose and upper part of the throat. The cochlea, a snail-shaped structure, is part of your inner ear.

Role of eustachian tubes

The eustachian tubes are a pair of narrow tubes that run from each middle ear to high in the back of the throat, behind the nasal passages. The throat end of the tubes open and close to:

Regulate air pressure in the middle ear
Refresh air in the ear
Drain normal secretions from the middle ear

Swollen eustachian tubes can become blocked, causing fluids to build up in the middle ear. This fluid can become infected and cause the symptoms of an ear infection.

In children, the eustachian tubes are narrower and more horizontal, which makes them more difficult to drain and more likely to get clogged.

Role of adenoids

Adenoids are two small pads of tissues high in the back of the nose believed to play a role in immune system activity.

Because adenoids are near the opening of the eustachian tubes, swelling of the adenoids may block the tubes. This can lead to middle ear infection. Swelling and irritation of adenoids is more likely to play a role in ear infections in children because children have relatively larger adenoids compared to adults.

Related conditions

Conditions of the middle ear that may be related to an ear infection or result in similar middle ear problems include:

Otitis media with effusion, or swelling and fluid buildup (effusion) in the middle ear without bacterial or viral infection. This may occur because the fluid buildup persists after an ear infection has gotten better. It may also occur because of some dysfunction or noninfectious blockage of the eustachian tubes.
Chronic otitis media with effusion, occurs when fluid remains in the middle ear and continues to return without bacterial or viral infection. This makes children susceptible to new ear infections and may affect hearing.
Chronic suppurative otitis media, an ear infection that doesn’t go away with the usual treatments. This can lead to a hole in the eardrum.

Risk factors

Risk factors for ear infections include:

Age. Children between the ages of 6 months and 2 years are more susceptible to ear infections because of the size and shape of their eustachian tubes and because their immune systems are still developing.
Group child care. Children cared for in group settings are more likely to get colds and ear infections than are children who stay home. The children in group settings are exposed to more infections, such as the common cold.
Infant feeding. Babies who drink from a bottle, especially while lying down, tend to have more ear infections than do babies who are breast-fed.
Seasonal factors. Ear infections are most common during the fall and winter. People with seasonal allergies may have a greater risk of ear infections when pollen counts are high.
Poor air quality. Exposure to tobacco smoke or high levels of air pollution can increase the risk of ear infections.
Alaska Native heritage. Ear infections are more common among Alaska Natives.
Cleft palate. Differences in the bone structure and muscles in children who have cleft palates may make it more difficult for the eustachian tube to drain.

Complications

Most ear infections don’t cause long-term complications. Ear infections that happen again and again can lead to serious complications:

Impaired hearing. Mild hearing loss that comes and goes is fairly common with an ear infection, but it usually gets better after the infection clears. Ear infections that happen again and again, or fluid in the middle ear, may lead to more-significant hearing loss. If there is some permanent damage to the eardrum or other middle ear structures, permanent hearing loss may occur.
Speech or developmental delays. If hearing is temporarily or permanently impaired in infants and toddlers, they may experience delays in speech, social and developmental skills.
Spread of infection. Untreated infections or infections that don’t respond well to treatment can spread to nearby tissues. Infection of the mastoid, the bony protrusion behind the ear, is called mastoiditis. This infection can result in damage to the bone and the formation of pus-filled cysts. Rarely, serious middle ear infections spread to other tissues in the skull, including the brain or the membranes surrounding the brain (meningitis).
Tearing of the eardrum. Most eardrum tears heal within 72 hours. In some cases, surgical repair is needed.

Prevention

The following tips may reduce the risk of developing ear infections:

Prevent common colds and other illnesses. Teach your children to wash their hands frequently and thoroughly and to not share eating and drinking utensils. Teach your children to cough or sneeze into their elbow. If possible, limit the time your child spends in group child care. A child care setting with fewer children may help. Try to keep your child home from child care or school when ill.
Avoid secondhand smoke. Make sure that no one smokes in your home. Away from home, stay in smoke-free environments.
Breast-feed your baby. If possible, breast-feed your baby for at least six months. Breast milk contains antibodies that may offer protection from ear infections.
If you bottle-feed, hold your baby in an upright position. Avoid propping a bottle in your baby’s mouth while he or she is lying down. Don’t put bottles in the crib with your baby.
Talk to your doctor about vaccinations. Ask your doctor about what vaccinations are appropriate for your child. Seasonal flu shots, pneumococcal and other bacterial vaccines may help prevent ear infections.
