Your middle ear is a hollow space behind your eardrum. The middle ear contains 3 tiny bones that transmit vibrations of your eardrum to the nerves in your inner ear.
Your eustachian tube connects the back of your throat to your middle ear.
Your ear canal is the tube that connects the outside of your ear to your eardrum.

What causes secretory otitis media?
Problems with your eustachian tube
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?

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
