Let's learn more about our ears. (The Ear) - Hearing and balance

We all know that our ears help us hear the sounds around us and talk to others. But did you know that there is a major control center inside the ear that helps you stand up straight, walk, and balance without falling? The ear is actually a much more complex and amazing organ than we think. So today, let's talk about our ear, how it works, the diseases it can cause, and how to take care of it.

What are the two main functions of the ear?

The ear has two main functions: hearing and maintaining balance in the body.

1. How does hearing happen?

Simply put, this is an amazing process.

• Sound waves enter our ears.
• These sound waves travel and hit the eardrum, or in medical terms, the tympanic membrane . Then the eardrum begins to vibrate.
• This vibration is transmitted to three tiny bones in the middle ear (called `Ossicles` ). These three bones amplify the vibration and send it to the inner ear.
• When you go into the inner ear, there are very fine hair-like cells called stereocilia . These convert those vibrations into electrical signals.
• Finally, these electrical signals travel along the nerves to the brain. The brain interprets these signals as "sound" and tells us what it is.

2. How do you control balance?

This system inside the ear keeps you from falling when you walk, run, or bend your head.

• Our inner ear has a system of fluid-filled semicircular canals .
• When you move your head from side to side, the fluid inside these tubes also moves in that direction.
• When this fluid moves, the fine hair-like sensors there are stimulated.
• This information travels to the brain via the vestibular nerve .
• The brain uses that information to send signals to the body's muscles, helping to keep you balanced and prevent you from falling.

Let's learn about the parts of the ear.

The ear can be divided into three main parts: the outer ear, the middle ear, and the inner ear. These are separated from each other by the eardrum.

What are the common diseases and conditions that affect the ear?

Various medical conditions can affect our ears. Let's learn about a few of them.

Earache/Ear Infection (Otitis Media)

This most often occurs in the middle ear. This infection occurs when bacteria or viruses enter the middle ear and become trapped. This condition is more common in young children than adults. It can usually be treated with antibiotics. In some severe cases, ear tubes may be needed.

Swimmer's Ear (Swimmer's Ear / Otitis Externa)

This is an infection of the outer ear, that is, the ear canal. Despite its name, it is not just for swimmers. When water gets into the ear, it can be caused by bacteria or fungi growing in the moisture. Also, inserting objects like cotton swabs into the ear can damage the skin of the ear and increase the risk of developing this infection.

Ruptured Eardrum

This is a hole in the eardrum. This can be caused by infections, trauma to the ear, loud noises, or foreign objects in the ear. Most of the time, it heals on its own within a few weeks. However, in some cases, surgery (`Tympanoplasty`) may be required.

Eustachian Tube Dysfunction

This condition occurs when the Eustachian tube, which we discussed earlier, becomes blocked. This changes the pressure inside the ear, causing symptoms such as a feeling of fullness in the ear, ringing in the ears (tinnitus), and mild hearing loss.

Otosclerosis

What happens in this is that the little bones in the middle ear gradually harden and lose their ability to vibrate. Then sound waves don't reach the inner ear properly. Because of this, hearing gradually begins to decrease. This usually requires surgery.

Vestibular Neuritis

This condition is caused by swelling of the nerve responsible for balance in the inner ear. The main symptom is sudden, severe dizziness (vertigo) . It may also be accompanied by nausea and vomiting. This requires medication and sometimes physical therapy.

Symptoms that can indicate an ear problem

If you have a problem with your ear, you may experience one or more of the following symptoms. If you have any of these symptoms, it is important to see a doctor as soon as possible.

How to keep your ears healthy?

Our ears are very valuable and sensitive organs, so it is our responsibility to take care of them.

• Avoid loud noises: Avoid listening to music with headphones at high volume, and avoid being in places with loud noises (e.g. factories, music concerts). If you must be in such places, wear ear plugs.
• Keep your ears dry: Minimize water from getting into your ears while bathing or swimming. Use ear plugs if you are swimming. If water does get into your ears, tilt your head to the side to drain it.
• Don't put anything in your ear: As we mentioned earlier, don't put cotton swabs or other sharp objects in your ear. Earwax is a natural product that naturally comes out. It's for your ear's protection. If you think you have a blockage, see a doctor.
• Protect yourself when playing sports: If you play contact sports, wear head and ear protection.
• Seek medical advice promptly: If you experience any symptoms such as ear pain, hearing loss, or dizziness, do not ignore them and see your doctor immediately.
