Ear Infection (Middle Ear)

Overview

Ear infections, also known as acute otitis media, happen when the middle ear gets infected. The middle ear is the space behind your eardrum, filled with air and tiny bones that help you hear. Kids are more prone to getting ear infections than adults.

Symptoms

Ear infections often appear quickly. The symptoms usually develop rather suddenly.

When to see a doctor

Ear infections can have various signs and symptoms, and it's crucial to get a proper diagnosis and treatment right away. If you notice any of these issues, contact your child's doctor:

  • If the symptoms last longer than 24 hours: This is a key sign that something might need attention. A lingering earache, ear pressure, or other discomfort warrants a check-up.

  • If your child is under 6 months old and showing any ear infection symptoms: Babies this young may not be able to communicate their discomfort in the same way older children do. Any changes in behaviour, like fussiness or difficulty sleeping, are important to address.

  • If the ear pain is very strong: Severe pain is a significant indicator of a possible ear infection. If your child is in a lot of distress, don't hesitate to call the doctor.

  • If your baby or toddler is unusually sleepy or cranky after a cold or other respiratory illness: A cold can sometimes lead to ear infections. If your child is extra tired or irritable following a cold, it could suggest an ear infection developing.

  • If you see fluid, pus, or blood coming from the ear: This is a clear sign of a problem and needs immediate medical attention. This could indicate a more serious infection.

Remember, these are just some common signs. If you have any concerns about your child's health, always consult their doctor.

Causes

Ear infections happen when germs like bacteria or viruses get into the middle ear. These germs often enter the ear because of another illness, like a cold, the flu, or allergies. These illnesses cause the passages in your nose and throat, and the eustachian tubes (tiny tubes connecting the middle ear to the back of the throat), to swell and get blocked. This blockage makes it easier for germs to travel to the middle ear and cause an infection.

Risk factors

Ear infections can happen to anyone, but some things make you more likely to get them. Here are some common risk factors:

  • Age: Babies and toddlers (6 months to 2 years old) are more prone to ear infections. This is because their eustachian tubes, the tiny tubes connecting the ear to the back of the throat, are still developing and smaller than those in older children and adults. Also, their immune systems are not yet fully formed, making them more vulnerable to infections.

  • Childcare: Children in group settings, like daycare centers, are more likely to catch colds and ear infections. They're exposed to more germs and viruses than children who stay at home.

  • Bottle-feeding: Babies who are bottle-fed, especially when lying down, are more susceptible to ear infections. When a baby drinks from a bottle lying down, milk or formula can easily flow back into the ear canal, leading to infection. Breastfeeding, on the other hand, is often associated with fewer ear infections.

  • Time of year: Ear infections are more common in the fall and winter. This is likely due to changes in weather patterns and increased indoor time, which can lead to more close contact with others and the spread of germs. People with allergies might also be more susceptible to ear infections when pollen counts are high.

  • Air quality: Exposure to things like cigarette smoke or high levels of air pollution can make it easier to get an ear infection. These irritants can weaken the body's defenses and increase the risk of infection.

  • Genetics: Some groups of people, such as Alaska Natives, have a higher rate of ear infections than others. This may be due to a combination of genetic factors and environmental influences.

  • Medical conditions: Children with cleft palates, a birth defect where the roof of the mouth does not form properly, may have difficulty with the eustachian tubes draining. This can make them more prone to ear infections. The unique structure of the eustachian tube in these children can lead to issues with proper drainage and increase the risk of infection.

Complications

Ear infections are usually not a big deal in the long run. However, repeated or severe ear infections can sometimes lead to problems.

  • Hearing Loss: Ear infections can sometimes cause temporary hearing problems. This is fairly common, and often goes away when the infection clears up. But if you have repeated infections, or if fluid builds up in your ear, you might have more serious and lasting hearing loss. If the eardrum or other parts of the middle ear get permanently damaged, you could lose some hearing permanently.

  • Developmental Delays: Babies and young children who have trouble hearing, whether temporary or permanent, might have problems learning to talk, interact with others, and develop their skills. This is because hearing is so important for learning and development.

  • Spread of Infection: If an ear infection isn't treated properly or doesn't get better with treatment, it can spread to nearby areas. One example is mastoiditis, an infection in the mastoid bone behind the ear. This can damage the bone and cause pus-filled pockets. In very rare cases, a serious middle ear infection can spread to other parts of the skull, like the brain or the membranes surrounding the brain (meningitis). Meningitis is a serious illness.

  • Eardrum Tears: Most eardrum tears heal on their own within a few days (around three days). But sometimes, surgery is needed to fix a tear.

Prevention

Protecting your child's ears from infections can be done in several ways. Here are some simple steps to lower the chances of ear infections:

1. Keep Illnesses at Bay: Teach your children to wash their hands often and properly. This is crucial for preventing the spread of germs, including those that cause colds and other illnesses. Encourage them to cover their coughs and sneezes with their elbows, not their hands. Sharing utensils should also be avoided. If possible, limit your child's time in group settings like daycare. A smaller daycare group might help reduce exposure to illness. Keeping your child home from daycare or school when they are sick is another important step.

2. Avoid Smoke: Don't allow smoking in your home. Protect your child from secondhand smoke by staying in smoke-free environments, both at home and elsewhere.

3. Breastfeeding Benefits: If you can, breastfeed your baby for at least six months. Breast milk contains special proteins called antibodies that can help shield your baby from infections, including those that can cause ear infections.

4. Bottle Feeding Safety: If you're bottle-feeding, hold your baby upright while they feed. Never prop a bottle in a baby's mouth while they are lying down. Avoid placing bottles in a baby's crib.

5. Talk to Your Doctor About Vaccines: Discuss with your doctor which vaccinations are best for your child. Vaccines against the flu, pneumococcal bacteria, and other germs can help prevent ear infections. Your doctor can advise you on the best schedule and types of vaccines for your child's specific needs.

Diagnosis

Diagnosing Ear Infections and Related Conditions

Doctors typically diagnose ear infections and other ear problems by asking about your child's symptoms and conducting a physical exam. A crucial part of this exam involves using an otoscope, a lighted instrument that allows the doctor to see inside the ear, throat, and nasal passages. They might also use a stethoscope to listen to your child's breathing.

Often, a pneumatic otoscope is all the specialized equipment needed. This tool lets the doctor check for fluid behind the eardrum. The doctor gently pumps air against the eardrum. A healthy eardrum will move in response to this air. If the middle ear is filled with fluid, the eardrum won't move much, or not at all.

If the diagnosis isn't clear, if treatment isn't working, or if there are concerns about more serious issues, your doctor might order other tests. These tests help confirm the diagnosis and determine the best course of action.

Additional Diagnostic Tests:

  • Tympanometry: This test measures how the eardrum moves in response to changes in air pressure in the ear canal. Imagine the eardrum as a tiny drumhead. This test sees how well it responds to air being pumped in. It gives an idea of the pressure in the middle ear.

  • Acoustic Reflectometry: This test measures how much sound bounces back from the eardrum. A healthy eardrum absorbs most sound. If there's fluid in the middle ear, the eardrum reflects more sound. This helps doctors gauge the presence of fluid.

  • Tympanocentesis: In rare cases, a tiny needle is used to pierce the eardrum and drain fluid from the middle ear. This procedure is called tympanocentesis. The fluid is then tested to identify any viruses or bacteria causing the infection. This is often used when other treatments haven't worked.

  • Other Specialist Evaluations: If your child has had multiple ear infections or ongoing fluid buildup, your doctor may refer you to specialists like an audiologist (hearing specialist), speech therapist, or developmental therapist. These professionals can assess hearing, speech, language skills, and overall development.

Different Types of Ear Conditions:

Doctors use specific terms to describe different types of ear problems:

  • Acute Otitis Media (Ear Infection): This is the common term for ear infections. A doctor diagnoses this when they see fluid in the middle ear, notice signs of an infection, and if the symptoms came on suddenly.

  • Otitis Media with Effusion: This means there's fluid in the middle ear, but there are no current signs of infection.

  • Chronic Suppurative Otitis Media: This describes a long-term ear infection that has caused the eardrum to tear. Pus often drains from the ear in this case.

These different diagnoses help the doctor tailor the best treatment plan for your child's specific needs.

Treatment

Ear Infections in Children: When to Worry and What to Do

Many ear infections, especially in older children, can get better on their own without antibiotics. This "wait-and-see" approach is often recommended by doctors. However, the best course of action depends on several things, including your child's age and how severe the symptoms are.

When to expect improvement: Most ear infections start to improve within a few days, and often clear up completely within one to two weeks without any treatment. The American Academy of Pediatrics and the American Academy of Family Physicians often suggest a "watchful waiting" period as a possible first step.

When antibiotics might be needed: While some infections resolve on their own, antibiotics might be helpful in certain situations. However, overuse of antibiotics can make bacteria resistant to them. Always discuss the pros and cons of antibiotics with your child's doctor.

Managing pain and discomfort: Doctors can recommend ways to ease pain from an ear infection. These might include:

  • Pain relievers: Over-the-counter pain relievers like acetaminophen (like Tylenol) or ibuprofen (like Advil or Motrin) can help. Follow the instructions on the packaging carefully. Be very careful when giving aspirin to children or teens, as it's linked to a rare but serious condition called Reye's syndrome. If you have any concerns, talk to your doctor.
  • Ear drops: In some cases, anesthetic ear drops can reduce pain, but these are usually not necessary if the eardrum is healthy.

When immediate medical attention is needed: Doctors might recommend antibiotics sooner rather than later in these situations:

  • Very young children (under 6 months): Babies this young with a confirmed ear infection often get antibiotics right away without waiting.
  • Moderate to severe pain: If your child has significant ear pain (moderate to severe) lasting for at least 48 hours, or a fever of 102.2°F (39°C) or higher, a doctor may prescribe antibiotics sooner.
  • Persistent symptoms: If the infection doesn't improve after a few days or keeps coming back, your doctor may recommend further treatment.

Treating persistent fluid buildup: If your child has repeated ear infections (chronic otitis media) or fluid buildup in the middle ear after an infection clears (otitis media with effusion), your doctor might recommend a procedure to drain the fluid.

This procedure, called a myringotomy, involves making a small hole in the eardrum. This allows doctors to drain fluid from the middle ear. A tiny tube (tympanostomy tube) is often inserted into the hole to help keep the middle ear ventilated and prevent fluid buildup. These tubes typically stay in place for several months to a year before falling out on their own. In some cases, they might need to be surgically removed.

Chronic ear infections: If the infection causes a hole or tear in the eardrum (chronic suppurative otitis media), treating it often involves antibiotic ear drops. Your doctor might also show you how to gently remove fluid from the ear canal before administering the drops.

Follow-up care: Children with frequent ear infections or persistent fluid buildup in the middle ear need close monitoring. Your doctor will advise you on how often you should schedule follow-up appointments, which may include hearing and language tests.

Important Considerations for Parents: Always follow your doctor's instructions carefully for any prescribed medication or treatments. If your child misses a dose of antibiotics, talk to your doctor or pharmacist about the best course of action. Don't hesitate to ask questions and address any concerns you have.

Preparing for your appointment

To get help for ear problems, you'll probably first see your family doctor or pediatrician. If the issue continues, isn't getting better, or happens often, you might be sent to a specialist called an ear, nose, and throat (ENT) doctor.

Before your appointment, it's helpful to talk to your child about what the doctor might ask. If your child is old enough, they can help answer these questions. Adults should be ready to answer similar questions about themselves.

Here are some typical questions you'll likely be asked:

  • What problems are you seeing? Describe any signs or symptoms you've noticed.
  • When did these problems start? Knowing the timeline is important.
  • Is there ear pain? If so, how bad is it? Is it a mild, moderate, or severe pain?
  • Are there signs of pain in babies and toddlers? Look for things like pulling at their ear, trouble sleeping, or being unusually fussy. These could indicate ear pain.
  • Has your child had a fever? A fever is often a sign of infection.
  • Is there any fluid coming from the ear? If so, describe the color – is it clear, cloudy, or bloody?
  • Is there a hearing problem? Does your child react to quiet sounds? Does your older child frequently ask "What?" This could mean hearing loss.
  • Has your child had a cold, flu, or other respiratory illness recently? These illnesses can sometimes lead to ear infections.
  • Does your child have allergies? Seasonal allergies can sometimes affect ears.
  • Has your child had ear infections before? If so, when? Knowing about past infections can help the doctor.
  • Is your child allergic to any medicine? This is crucial information, especially if amoxicillin is involved. Knowing about allergies helps doctors avoid potential reactions.
