Dealing with an earache can be quite painful. Children are often more likely to develop ear infections than adults, which is why it’s important to understand why ear infections happen and how to spot the warning signs. After all, the majority of children will experience at least one ear infection by the time they turn three years old.

Causes of Ear Infections

Within the ears lie Eustachian tubes, which are small passages that connect the middle ear to the back of throat. Every time you yawn or swallow the Eustachian tubes open, which is why when an ear infection occurs this causes pain and pressure whenever you sneeze or swallow. During an infection, the Eustachian tube either swell or become blocked, which causes fluid buildup within the middle ear.

There are many things that can cause an ear infection but the most common causes include:

  • Changes in air pressure
  • Sinusitis
  • Smoking
  • Allergies
  • Common cold
  • Tonsillitis

As we mentioned above, children are more likely to experience ear infections because they have narrower Eustachian tubes. Children are also more likely to develop ear infections if they are dealing with another illness or infection such as a cold, are exposed to smoke or experience changes in climate or altitude.

Symptoms of an Ear Infection

Unfortunately, young children can’t always tell us when they are experiencing an ear infection; however, there are signs you can lookout for. A classic sign is pulling or tugging at the ear. You may also notice that your child is fussier than usual or cries when lying down. Your child may also become clingier.

If you notice pus draining from the ear or if your child is displaying sudden symptoms of hearing loss (e.g. not responding to vocal cues or sounds) then it’s time to bring them to an otolaryngologist as soon as possible. If your child’s ear infection is accompanied by a fever over 102 degrees F, it’s also important that you seek immediate medical care.

Of course, older children will be able to complain about pressure or pain in their ear, common signs of an infection. The pain may be dull and achy or it can be sharp and stabbing. Any ear pain warrants seeing an ENT doctor just to be on the safe side.

Treating Ear Infections

A simple ear exam is often all that’s needed to be able to diagnose an ear infection. While some ear infections will clear up on their own sometimes your ear, nose & throat doctor will provide you with antibiotic drops or even drops to help soothe pain. Children under 2 years old who have an ear infection will likely receive antibiotics.

Dealing with an ear infection? Think your child may have an infection? If so, an ENT doctor is the right person to turn to when these infections start brewing.
