JordanFluid behind the eardrum is commonly caused by an ear infection, often due to a viral or bacterial infection. Other causes can include Allergies, sinus infections, or changes in altitude. Treatment can involve addressing the underlying cause, such as with antibiotics for an infection, or using decongestants or antihistamines to help drain the fluid.

How does otitis media affect the eardrum?
Otitis media can cause inflammation and fluid buildup behind the eardrum, leading to pain, pressure, and potential rupture of the eardrum. This can result in symptoms like ear pain, decreased hearing, and sometimes drainage from the ear.
When you hear sound which vibrates first. Your eardrum or the fluid in the cochlea?
The sound waves first vibrate the eardrum, which then transmits the vibrations to the fluid in the cochlea. The fluid in the cochlea contains sensory hair cells that convert the vibrations into electrical signals that the brain interprets as sound.
What takes sound waves from the inner ear to the brain?
Sound travels in waves. Our ears pick up these waves and funnel them to the eardrum. The eardrum interprets them as vibrations. These vibrations pass through the eardrum, into the inner ear via the hammer, anvil, and stirrup bones. This causes fluid in the inner ear to bend tiny hairs which convert the vibrations into nerve impulses. The auditory nerve then sends the signals to the brain, which converts them again into the sound of what is heard.
Can you have buildup of wax behind the airdrum?
Yes, wax buildup can occur behind the eardrum, known as otitis media with effusion. This typically happens when fluid becomes trapped in the middle ear space, often leading to hearing loss and discomfort. Treatment may involve ear tube placement or medication to reduce inflammation and aid drainage.
What causes the auditory ossicles to vibrate?
The auditory ossicles vibrate in response to sound waves transmitted from the eardrum. When sound waves hit the eardrum, it causes the ossicles (malleus, incus, stapes) to amplify and transmit the vibrations to the inner ear. These vibrations are then converted into electrical signals that are sent to the brain for processing as sound.
