What is the earstone? Is it earwax?

When it comes to earstone, many friends must be unclear about earstone and earwax, thinking that earstone is what we usually call earwax. In fact, the two are completely different concepts.

First, the position of earstone and earwax is different. Our ears look small, but they are hidden in the mystery, which are divided into outer ears, middle ear and inner ear. Earstone is located in our inner ear; earwax, also called 外, is located in the outer ear canal.

Second, there is a big difference between the composition of earstones and earwax. On the inside of our binocular ears, there is a structure that regulates the balance of the body. Among them, the balloon and ellipse sac are one of the important structures. This structure has the crystallization of calcium carbonate in the center of the center. The size is between 20 and 30 microns because The shape is like a small stone, so it is called the earstone, and the balloon and the ellipse sac are called the otoscope. The earwax is mainly formed by the secretions, cell debris, and external ear canal produced by the outer ear canal glandular gland.

Third, earstone and earwax have different impacts on our body. As we all know, the ears are auditory organs, but the ears are actually the balanced organ of the human body. The main role of the earstone is to allow the human body to induced a straight line acceleration and maintain the function of the inner ear vestibular balance system. Essence Once the earstone falls off, it will cause strong dizziness.

The main role of earwax is to protect the external ear canal and block the external microorganisms into the ear canal. People generally discharge the earwax by chewing, yawning or speaking. However, there will be too much earwax secretion, compressing and blocking the external ear canal, causing ears, tinnitus, and hearing to decrease.

In daily life, people have rarely seen earstones, but often meet with earwax. Presumably friends already have pictures in their minds at this time!

Why do "otolith disease" make people dizzy?

In fact, otolith disease also has a tall name, called "benign position parity dizziness". So why does otolith disease dizzy?

Under normal circumstances, the earstone is attached to the surface of the balloon and oval sac. After various reasons, the ear stones will fall off, and the earstone will enter the semi -regulatory tube located next to the balloon and oval sac. When the head position of the human body changes, the earstone in the semi -regulatory tube also moves follow, which causes the cap cell in the lymph fluid to turn the cilia of the capillary and cause abnormally discharge of the cap cell.

Under normal circumstances, the inner hair cells of the two ears are equal, so when transmitted to the vestibular center, the brain can process these balanced signals. However, when one ears fall off and the other earstone inside the other ear does not fall off, the hair cells in the ears are unevenly discharged, or the vestibular information input to the vestibular center in both sides is uneven. Sports information, so it feels dizzy.

How to judge whether you have "otolith disease"?

Although "otolith disease" belongs to the Department of ENT, many patients with dizziness believe that this is caused by insufficient blood supply to the brain or cervical spondylosis. Therefore, they went to neurology and orthopedics. Because people lack the understanding of this disease, they often delay treatment. In fact, it is not difficult to treat otolite. The key is to judge whether this disease is obtained in a timely manner.

Xiaobian will take you to understand the incidence of otolith disease:

1. When the header changes, short dizziness occurs suddenly, usually not more than one minute.

2. During the dizziness, you can feel rotated by the sky, accompanied by eye tremor, nausea, and vomiting symptoms, but it will not be accompanied by symptoms such as tinnitus, ears and hearing decreased.

3. After keeping the header unchanged, the symptoms of discomfort will disappear quickly, but the head position will be changed again, and the symptoms will appear again.

4. After the attack, the body usually has no discomfort, or dizziness, headache and mild imbalance.

Of course, the above can only be used as a preliminary judgment basis, or they must go to a regular hospital for a professional doctor to confirm the diagnosis.

There are many induced factors of otolith, such as tiredness and emotions such as tiredness, staying up late, great mental stress, tension, anxiety and other bad living habits and emotions. Diabetes, hypertension and other chronic diseases, sudden deafness, vestibular neuritis, ear trauma and other ear diseases, as well as the aging of the otoscanus, can induce otolith disease. Therefore, friends should develop good living habits in daily life, maintain the rules of schedules, exercise more, pay attention to protecting the head, and avoid the occurrence of otolith disease as much as possible.
