What is secretory otitis media?

Secretory otitis media is a build up of fluid in your middle ear, usually after a middle ear infection (otitis media).

  • Although it can happen after an ear infection, the fluid in secretory otitis media isn't infected

  • Secretory otitis media can happen at any age but is most common in children

  • You may feel a fullness in your ear and have some hearing loss

  • Doctors look in your ear and use a sound wave test to tell if you have fluid in there

  • Doctors may need to make an opening in your eardrum to let fluid drain

What causes secretory otitis media?

Normally, you release pressure in your middle ear when you swallow. Swallowing causes your eustachian tubes to open, which can happen 3 to 4 times per minute. If an eustachian tube is blocked, fluid builds up in your middle ear so that your eardrum can't move the way it should.

Eustachian tube blockage can happen when colds or allergies cause the lining of the eustachian tube and adenoids to swell. Adenoids are clumps of tissue that help fight infection and are right near the opening of the eustachian tube.

What are the symptoms of secretory otitis media?

  • A feeling of fullness in your ear

  • A popping or crackling sound when you swallow

  • Some hearing loss

  • Sometimes, loss of balance

If young children have secretory otitis media with hearing loss for a long time, they can have trouble learning how to speak. Secretory otitis media also raises the risk of getting more ear infections (acute ear infections Ear Infection (Acute Otitis Media) Your middle ear is a hollow space behind your eardrum.

How can doctors tell if I have secretory otitis media?

Doctors will:

  • Look at your ear with a handheld light

  • Do a sound wave test to check for fluid (called tympanometry)

  • Do a hearing test

How do doctors treat secretory otitis media?

Most people will get better without treatment. Antibiotics don't help secretory otitis media.

To briefly relieve the fullness in your ear, you can breathe out while you close your mouth and pinch your nose shut.

If your symptoms last more than 3 months, a doctor may need to:

  • Make an opening in your eardrum to let the fluid drain

  • Place a small tube in your eardrum to let air behind it and keep fluid from building up again

  • Do surgery to take out your adenoids
