Patient Education


Ear Infections

Ear infections are the most common reason parents bring their child to a doctor. Three out of four children will have at least one ear infection by their third birthday. Adults can also get ear infections, but they are less common.

The infection usually affects the middle ear and is called otitis media. The tubes inside the ears become clogged with fluid and mucus. This can affect hearing, because sound cannot get through all that fluid.

If your child isn't old enough to say "My ear hurts," here are a few things to look for:

  • Tugging at ears
  • Crying more than usual
  • Fluid draining from the ear
  • Trouble sleeping
  • Balance difficulties
  • Hearing problems

Your health care provider will diagnose an ear infection by looking inside the ear with an instrument called an otoscope.

Often, ear infections go away on their own. Your health care provider may recommend pain relievers. Severe infections and infections in young babies may require antibiotics.

Children who get infections often may need surgery to place small tubes inside their ears. The tubes relieve pressure in the ears so that the child can hear again.

Fistulas

A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Some people are born with a fistula. Other common causes of fistulas include:

  • Complications from surgery
  • Injury
  • Infection
  • Diseases, such as Crohn's disease or ulcerative colitis

Treatment depends on the cause of the fistula, where it is, and how bad it is. Some fistulas will close on their own. In some cases, you may need antibiotics and/or surgery.
