You may have dizziness, loss of balance, hearing loss, and a ringing in your ear. This rare condition happens when a benign (noncancerous) tumor grows on the vestibulocochlear nerve connected to the inner ear. Related conditionsĬonditions in or adjacent to the inner ear can affect balance and may also sometimes cause hearing loss. You may feel vertigo (a room spinning sensation), dizziness, lightheadedness, or unsteady on your feet.īalance problems can happen even if you’re sitting or lying down. Most balance problems are caused by issues in your inner ear.

difficulty honing in on where a sound is coming from.

difficulty hearing speech against other background noises.

Hearing loss can happen when your inner ears can’t send nerve signals to your brain as well as they used to. The nerves and hair sensors in the inner ears can get damage due to aging or from being around too much loud noise for too long. Inner ear problems that cause hearing loss are called sensorineural because they usually affect the hairs or nerve cells in the cochlea that help you hear sound. Inner ear conditions can affect your hearing and balance. This is why you may feel dizzy for a little while even when you stop moving or are on solid ground. If you’re on a rollercoaster or a boat that’s moving up and down, the fluid in your inner ears might take a while to stop moving.

In turn, the brain tells your body how to stay balanced. These movement and balance sensors send electrical nerve messages to your brain. The semicircular canals are connected by “sacks” in the vestibule that have more fluid and hairs in them. When your head moves around, the fluid inside the semicircular canals shift around. This helps them measure motions no matter what position you’re in.

The semicircular canals sit at right angles to each other. The hairs act like sensors that help you with your balance. They’re filled with liquid and lined with fine hairs, just like in the cochlea, except these hairs pick up body movements instead of sounds. The 3 semicircular canals are loop-shaped tubes in the inner ear. The balance parts of the inner ear are the vestibule and the semicircular canals.

The electrical signals are sent to the brain through the hearing (auditory) nerves.

The “dancing” hairs in the cochlea convert the movement from sound waves into electrical signals.

The movement of fluid in your inner ear makes the tiny hairs in the cochlea bend and move.

The movement from the middle ear leads to pressure waves that make the fluid inside the cochlea move.

Sound waves make your eardrum vibrate and move the 3 tiny bones in your middle ear.

The sound waves travel down the ear canal to your eardrum in the middle ear.

The outer ear (the part that you can see) acts like a funnel that sends sounds into your ear canal from the outside world.

There are several steps that have to happen from outer ear to inner ear for a person to hear a sound: This acts like the body’s “microphone.” It contains 4 rows of tiny hairs that pick up the vibrations from the sound waves.

It contains a smaller, sensitive structure called the organ of Corti. It looks like a small spiral-shaped snail shell. The cochlea works with parts of the outer and middle ear to help you hear sounds.

The parts of the inner ear are attached but work separately to do each job.
