Tinnitus is caused by a malfunction of the ear. But that's just natural, because it's tinnitus! You would think.
However, ear problems have more than one cause.
There are many different parts of the ear, each of which can cause tinnitus.
Therefore, it is very difficult to simply say that there is something wrong with the ear.
Let's take a look at each of the ear malfunctions that can cause tinnitus.
Tinnitus has several causes, which are explained in "The causes of tinnitus are many and varied, and even doctors have difficulty quickly identifying them".
Please refer to this article.
Tinnitus caused by the outer ear
The outer ear is from the ear canal to the eardrum.
When the outer ear is the cause of tinnitus, the main factors are
- ear wax
- foreign body
- Inflammation
Basically, something is causing the ears to become clogged or inflamed due to damage to the ears from ear cleaning, etc.
Tinnitus caused by the middle ear
The middle ear is the part of the ear, such as the eardrum and ear ossicles, before sound is converted into electrical signals.
When the middle ear is the cause, the main factors are
- Inflammation
- blood flow obstruction
- fluid retention
- Tumor
- muscle spasm
Inflammation is the result of viruses such as influenza, which can cause eardrum inflammation.
Otitis media can also cause tinnitus.
It can also be caused by poor blood flow due to inactivity or other factors.
Residual fluid is water that can seep out of the ear cells and accumulate due to inflammation. This water is the effusion.
Other possible factors include tumors and muscle spasms.
Tinnitus caused by the inner ear
The inner ear is the part called the cochlea, which converts sound into electrical signals and delivers them to the brain, up to the auditory nerve.
When the inner ear is the cause, the main factors are as follows
- Inflammation
- blood flow obstruction
- Increased inner ear pressure
- lymph fluid
Mostly the same factors as in the middle ear.
When lymphatic fluid is the cause, it is also called Meniere's disease.
As you can see, there are many different parts of the ear, each of which has its own factors that can cause tinnitus.
