Can you be deaf without a tympanic membrane, and why is it possible to be deaf even if your tympanic

We all know that we have eardrums in our ears, but not many people have seen them. Usually take a flashlight to shine in the ear, you can see a white reflective point that is the eardrum, but to see its outline clearly, you need to see it under the otoendoscope, because the eardrum is too small, not as big as our little fingernail cover, and the thickness is only millimeters, which is very thin. Such a structure makes the eardrum prone to perforation under external forces such as slapping or in the case of otitis media.

So after the eardrum is perforated, we can't hear the sound?

The tympanic membrane does play a very important role in the process of sound conduction, when the sound is transmitted from the air to the eardrum, the tympanic membrane begins to vibrate, and the effective vibration area of the tympanic membrane is much larger than that of the rear pedal foot plate, through the principle of fluid mechanics, the sound pressure of the sound acting on the vestibular is expanded by more than ten times; At the same time, the amplitude of the eardrum is also twice as large as that of the malleus stem behind it, so that the sound is amplified when it reaches the ossicular chain; The presence of the eardrum also improves the auditory sensitivity of the cochlea.

Therefore, the tympanic membrane is equivalent to a sound amplification device, when the eardrum is perforated, this amplification device is damaged, and the hearing will be affected to a certain extent, if the eardrum is perforated in a large area or even without the eardrum, it will not be completely inaudible. In general, the larger the area of tympanic membrane perforation at the same sound frequency, the more hearing damage there is; And when the eardrum is perforated, we will have more difficulty listening to low-frequency sounds. The degree of hearing damage is also related to the location of the tympanic membrane perforation and whether the ossicular chain is affected.

In addition, when the tympanic membrane is perforated, it is necessary to avoid water in the ear when bathing and washing the face, so as to prevent sewage from entering the ear canal and causing infection, which will make the wound of the tympanic membrane perforation unable to heal on its own for a long time, and even expand the perforated area.

Without the eardrum, the loudness of human listening will be reduced to varying degrees, and the maximum impact on hearing will be 35 decibels. The eardrum can be perforated due to external force or otitis media. Generally, if the ear is injured by an external force, the tympanic membrane perforation is not serious, it can heal itself.

If the tympanic membrane is perforated due to otitis media or serious injury, you can selectively do tympanic membrane repair surgery based on the impact on yourself. If the eardrum is broken, you can go to the hospital to have your hearing checked.

There are several reasons for normal hearing loss in the eardrum, which can be conductive hearing loss caused by secretory otitis media in the middle ear or neural hearing loss caused by abnormal function of the auditory nerve in the inner ear. Generally speaking, neural deafness caused by abnormal function of the auditory nerve in the inner ear is more common, and there are many cases of neurological deafness, such as noise deafness, drug-induced deafness, hereditary deafness, acoustic neuroma, and vestibular aqueduct enlargement can also cause neurological deafness, and the tympanic membrane is often normal when neurological deafness occurs.

For people who are originally normal, it will not be a big problem to lose it, or even be able to find it. Some patients with congenital dysphasia have no development of the auricle, external auditory canal, and middle ear at all, and the hearing loss is only about 60db. It can be seen that the role of the eardrum is not very huge.

Organic rubbing of the outer ear and tympanic membrane leads to abnormal sound conduction and acoustic nerve rubbing. Your current examination describes the eardrum and external auditory canal. In addition, traditional Chinese medicine believes that the kidney is the main ear, and kidney deficiency with insufficient congenital endowment will also cause hearing abnormalities.

The reasons for this should be further clarified at this time.

"Eardrum" is the term of doctors, and the common people call it "eardrum".

In the minds of many people, the eardrum is the most important part of the auditory system. If you have a problem with your eardrum, you will become deaf, and if you have a normal eardrum, you should not have a hearing problem. Therefore, patients often wonder:

The doctor has confirmed that my eardrum is normal, why am I deaf? Even I am very worried about the invagination of the eardrum that occurs when people with normal hearing suffer from colds, and I believe that the inversion of the eardrum will inevitably lead to severe hearing loss.

In fact, in the human auditory system, the eardrum, despite its importance, plays only a "small role". The main function of the eardrum is to transmit external acoustic signals to the inner ear in an appropriate way. In addition, the eardrum also has the ability to amplify sound signals, which is about Although it is a lot, it is not a big problem for people with normal hearing, and it is not even noticeable.

Some patients with poor premature development have no development at all in the pinna, external auditory canal, and middle ear, and the hearing loss is only about 60db, which is not very severe in terms of deafness. It can be seen that the role of the eardrum is smaller than people think. More important in the auditory system is the inner ear and the central part of the auditory part behind it.

Something goes wrong with these parts, which we call sensorineural hearing loss. Patients with sensorineural hearing loss may not only be unable to hear small sounds, but also have problems such as poor auditory discrimination and revival. Also, the degree of hearing loss is more severe.

Therefore, a normal eardrum can also cause deafness, and it may be more severe.

Normal eardrum can only mean that the eardrum is good There are many reasons for hearing loss The tympanic membrane is only one of the causes of deafness Hearing loss may have ear canal disease Hearing loss is caused by the auditory nerve There are many reasons After hearing loss, please choose hearing aids in time.

It may be that there is a disease of the auditory nerve or the middle ear, the tympanic membrane is only a part of the external auditory canal, and there are many physiological structures in the middle and inner ears, and if it is damaged, it is also the same hearing loss.

There are many causes of deafness, such as a normal eardrum, which may be caused by damage to the ear nerve, bacterial infection, or even a blockage of ear canal secretions.

Deafness can be divided into many natures, conductive deafness, neural deafness, and mixed deafness. The eardrum is normal, but it does not mean that there is no problem with the inner ear of the middle ear, or that there is a problem with the auditory nerve, which can lead to deafness.

The human ear includes the outer ear, the middle ear, and the inner ear, the eardrum is the middle ear, which plays a certain role in sound amplification, even if the perforation of the eardrum does not have a great impact on the sound, the perception of sound is the auditory system of the inner ear, and the problem of the inner ear is irreversible.

It is possible that there is a problem with the auditory nerve in the inner ear.

There are many causes of hearing loss.

Neurological, impaired physical skills.

Hearing loss with tympanic membrane perforation is recommended, so it is recommended that you go to the hospital for examination.

There are many causes of deafness, tinnitus, and Eustachian tube obstruction, which need to be diagnosed**.; Inverted eardrum can cause hearing loss or deafness, and it is recommended to undergo a **test to confirm whether it is inflammation or other causes**.

A good eardrum does not mean that there will be no hearing loss, and there are many reasons for hearing loss, so it is recommended to diagnose it after examination.

The eardrum is just one part of the auditory system, and problems with any part of the other auditory system can cause hearing loss.
