Ear Infections

An ear infection happens when a bacterial or viral infection affects the ear. These can be really painful, due to fluid build-ups within the ear. This type of infections could be either persistent (chronic) or acute. Acute ear infections are painful, no matter how brief in terms of duration, while chronic ear infections can represent the cause of permanent harm to the middle and inner ear.

There are 3 main types of ear infections. They correspond to the 3 fundamental elements of the ear: inner, middle and outer ear, as follows:

  • Inner ear infections. This affects the most internal part of your ear. The inner ear carries the labyrinth, which is responsible for balance. The cochlea, part of the labyrinth, is a snail-formed organ that converts sound vibrations from the middle ear into electric indicators. The auditory nerve transmits those indicators from the cochlea to the brain.
  • Middle ear infections. The middle ear is the region that is located in the back of your eardrum. It is positioned between the eardrum and the internal ear. Within the middle ear, there are 3 tiny bones referred to as the malleus, incus, and stapes. These bones have the purpose of transmitting sound vibrations from the eardrum to the inner ear. A middle ear infection is also referred to as otitis media. This is due to fluid being trapped in the back of the eardrum, which can lead the eardrum to bulge. Along with an earache, you can experience a feeling of fullness in your ear. The symptoms of otitis media can include a fever, as well. You may additionally have hearing problems.
  • Outer ear infection. The outer ear is that part of your ear that extends out of your eardrum to the outside of your head. An outer ear infection, also referred to as swimmer’s ear, is likewise referred to as otitis externa. It regularly begins as an itchy rash. The ear may also become painful, tender, red and swollen. This type of ear infection regularly develops due to water that remains in the ear after swimming or bathing. The moisture will become a favorable condition for bacteria to grow and multiply. If your outer ear is scratched by gadgets that you use or by touching it with your fingers or nails, a bacterial infection can occur.

  • Air bubbles or fluid in the middle ear;
  • Fluid draining from the middle ear;
  • A perforation withinside the eardrum;
  • A collapsed eardrum.

If your infection is advanced, your medical doctor may also take some fluid from your ear to analyze in order to decide whether or not some antibiotic-resistant microorganisms are present and are the underlying cause of the infection. They may additionally order a computed tomography (CT) test of your head to decide if the infection has unfolded past the middle ear. You may also need a hearing test, particularly in case you are affected by persistent ear infections.

Another technique used to diagnose a likely ear infection is referred to as tympanometry. It's used to assess how well your ear is working. An easy assessment can also be done, especially if it seems that an infection has brought on hearing loss problems.

Most ear infections are commonly easily solved; however, they can recur. These uncommon and possibly severe complications may accompany ear infections:

  • Hearing loss;
  • Speech or language delay in youngsters;
  • Mastoiditis (a contamination of the mastoid bone withinside the skull);
  • Meningitis (a bacterial contamination of the membranes protecting the brain and spinal cord);
  • A ruptured eardrum.

Other close by components of the ear additionally may pose a risk when talking about ear infections. These can also be affected by an infection:

  • The eustachian tubes. The eustachian tube is a small passageway that connects the top part of the throat to the middle ear. Its process is to deliver clean air to the middle ear, drain the fluid and preserve the air pressure at a consistent degree between the nostril and the ear.
  • Adenoids. Adenoids are small pads of tissue positioned at the back of the lower back of the nostril, above the throat, and close to the eustachian tubes. Adenoids are ordinarily made from immune cells. They combat off infections by trapping microorganisms that come from the mouth.

  • Clumsiness or trouble keeping balance;
  • Trouble listening to or responding to quiet sounds.

 

Why are youngsters much more likely than adults to get ear infections?

There are numerous explanations why youngsters are much more likely than adults to get ear infections.

A baby's immune system is not as powerful as an adult’s, due to the fact that it is in the process of developing. This makes it more difficult in general for children and babies to combat infections.

As a part of the immune system, the adenoids combat the microorganisms passing from the nostril and mouth. Sometimes microorganisms get trapped within the adenoids, inflicting a persistent infection that could then travel directly to the eustachian tubes and the center ear.

 

How does a health practitioner diagnose a middle ear infection in children?

The first step a health practitioner will take is to ask you about your baby's health. Has your baby had a sore throat recently? Is he having trouble sleeping? Is he pulling at his ears? If an ear infection is suspected, a doctor may apply an instrument, referred to as an otoscope, to check the eardrum. A red, bulging eardrum shows an infection.

A health practitioner additionally might also use a pneumatic otoscope, which blows a gasp of air into the ear canal, to test for fluid at the back of the eardrum.

A tympanometry, which makes use of sound tones and air strain, is a diagnostic tool that a health practitioner would possibly use if the prognosis is not clear. A tympanometer is a small, tender plug that carries a tiny microphone and speaker in addition to a tool that varies the air pressure within the ear. It measures how bendy the eardrum is at exceptional pressures.

 

How is an acute middle ear infection treated in children?

Many doctors will prescribe an antibiotic, including amoxicillin, to be taken for seven to ten days. Your health practitioner additionally might advise you to give your baby over the counter pain relievers including acetaminophen or ibuprofen, or eardrops, to assist with fever and ache.

If your health practitioner cannot make an exact prognosis solely based on the symptoms and your baby does not have excessive ear pain or a fever, he might ask you to wait for a few days to see whether or not the earache goes away. If your health practitioner prescribes an antibiotic, it is crucial to make sure that your baby takes it precisely as prescribed and for the entire period of time. Even if the symptoms of your baby tend to improve in the very next days, the infection has absolutely not cleared from the ear. Stopping the antibiotics too quickly will allow the infection to return and become stronger. It's crucial to go back on your baby's check-up visit, in order that the health practitioner can take a look and see if the infection is gone.

 

Risk factors in children

One of the reasons children are much more likely than adults to get ear infections is that their eustachian tubes are small and horizontal unlike the tubes in adults. They have smaller eustachian tubes, so they pose a higher risk for developing an ear infection. Make sure you do not expose your child to smoke, as that can also increase this risk. Having seasonal hypersensitive reactions or frequent common colds additionally place them at a higher chance, too.

 

Ear infections while pregnant

Ear infections during pregnancy can occur for a number of reasons. Usually, they are relatively harmless.  However, if you have any kind of infection during pregnancy, you must see a doctor. If left untreated, ear infections can be harmful to you and to your growing baby, and in rare cases it can lead to complications. But in most cases, ear problems during pregnancy are mild and temporary.

A common ear infection that can occur during pregnancy is swimmer's ear. This ear infection occurs in the external ear canal, usually after swimming in dirty water or accidentally scratching the inside of the ear. A very rare and transient ear problem that can occur during pregnancy is sudden sensorineural hearing loss (SSNHL). It is not an infection, and researchers do not know exactly why some people develop this rare disease during pregnancy. However, it usually occurs in the second or third trimester and heals in less than 10 days. Tell your doctor immediately if you have an earache or changes in your hearing.

 

Causes of Ear Infections During Pregnancy

Infections in general are more common during pregnancy. Ear, nose, and throat changes during pregnancy, in particular, can increase the risk of ear infections. An ear infection can be caused by a viral or bacterial infection.

Changes in pregnancy that make it more likely for you to develop an ear infection include:

  • A higher basal metabolic rate (BMR). During pregnancy, your body needs higher levels of oxygen and a larger volume of blood. This means that your heart is also working harder to move all that fluid. If fluid builds up in your ear, you may get an earache, though not necessarily an infection.
  • Hormonal changes. Estrogen and progesterone levels increase during pregnancy. These hormones can affect your immune system, making you more susceptible to diseases caused by bacteria and viruses. However, the exact relationship between hormones and infections is not entirely clear.
  • More fluid. Increased blood flow means that more fluid remains in your body. This can cause other side effects. For example, you may have noticed that you often have a stuffy nose during pregnancy. Having more fluids in your nose and sinuses during pregnancy can increase the risk of an ear infection.

Changes during pregnancy can also cause other temporary ear problems, such as dizziness or vertigo. Your hearing and balance can be affected during pregnancy if you already have a preexisting medical condition, such as Meniere's disease. When it's cold, allergy, or flu season, everyone is at higher risk for ear infections and other infections.

Infection or damage to the inner ear can sometimes cause:

  • Dizziness;
  • Hearing loss;
  • Tinnitus (ringing in the ears).

 

Symptoms of an ear infection during pregnancy

Symptoms of an ear infection during pregnancy can include:

  • Burning pain, sharp or dull - especially when pressing the outer ear;
  • Swelling, redness or inflammation of the ear canal;
  • Itching in and around the ear;

The infection can spread and damage your hearing. Tell your doctor if you have other ear symptoms such as tinnitus (ringing in the ears). Other serious health conditions, such as high blood pressure or iron deficiency anemia, can also cause some ear symptoms such as tinnitus. In some cases, your doctor may refer you to an otolaryngologist, who is a doctor who specializes in a disease of the throat, nose, or ears.
