Why does my hearing still deteriorate even though my eardrum is repaired?

It has been argued that the eardrum is the most important part of the auditory system. If you have a problem with your eardrum, you will become deaf, but if you have a normal eardrum, you will not be deaf.

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 means that although there are a lot of them, it is not a big problem for people with normal hearing, and it is not even noticeable.

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. What really matters in the auditory system is the inner ear and the auditory center behind it.

If there is a problem with these parts, not only the small sounds cannot be heard, but also the problems of poor hearing ability and revitalization. So, the eardrum was repaired.

Hearing loss is also possible.

If the eardrum has been repaired, hearing will be restored, but it may be difficult to recover to the time before the injury. Hearing aids may be considered to compensate for hearing and prevent hearing loss.

In the minds of many people, the eardrum is normal, and hearing should also be normal, and many patients often ask this question, why is the eardrum good, why is the hearing reduced. In the human auditory system, the main role of the eardrum is to transmit the external sound signal to the inner ear in an appropriate way, the eardrum has the effect of amplifying sound, the most important part of the auditory system is the inner ear and the auditory center part, these parts have problems we call inducible neural deafness, inductive nerve deafness patients, not only small sounds can not be heard, but also have poor speech discrimination, uncomfortable to listen loudly, small voices and inaudible problems, And the hearing loss is severe, so a normal eardrum can also cause deafness, and it can be severe.

Perforation of the tympanic membrane is mostly caused by inflammatory or external factors that lead to incomplete periosteal trauma to the middle ear.

The inflammatory factors of tympanic membrane perforation are mostly caused by otitis media, and the main manifestations are: repeated pus discharge in the ear, hearing loss, tinnitus, etc.

External factors mostly refer to violent incidents, careless ear picking, cannon sounds, sneezing, etc., and the main manifestations are: pain in the ear, hearing loss, tinnitus, etc.

Once tympanic membrane perforation is confirmed, it is necessary to ensure that the ear is dry to prevent respiratory infection; Inflammatory perforation should be cleaned in time, ear fluid should be used, and antibiotics should be used to control the infection, periosteal perforation caused by external factors should be observed, and those who cannot heal themselves should choose surgery**.

Invaginated eardrums and "a lot of noise from the factory where you work" can affect hearing. Invaginated tympanic membrane is generally used to pinch the nose and puff up the eustachian tube** (the specific method is: pinch the nostrils and hold the breath to blow outward, but the force must be appropriate, if the force is too strong, it is easy to cause the tympanic membrane to rupture), of course, you can also go to the hospital for eustachian tube blowing**.

Below, I will give you a brief introduction to the knowledge of tympanic membrane inversion. The tympanic membrane, which divides the outer ear from the middle ear, is located at the bottom of the external auditory canal and is an oval, translucent membrane. The surface of the eardrum is shallow funnel-shaped, and when the eardrum is invaginated, the eardrum sinks in the direction of the middle ear.

The cause of invagination of the tympanic membrane is caused by an imbalance in the air pressure inside and outside the eardrum. In the nasopharynx, there is a tube that opens downward, backward, and outward, and the other end opens in the anterior wall of the eardrum, and this tube is called the eustachian tube (also called the eustachian tube). Its role is to communicate the tympanic cavity with the nasopharynx, so that the atmospheric pressure of the tympanic cavity and the external auditory canal is equal to maintain the equalization of the tympanic membrane pressure.

If you have serous otitis media, known as catarrhal otitis media, it can lead to dysfunction of the eustachian tube, which imbalances the atmospheric pressure inside and outside the eardrum. In this way, due to the atmospheric pressure from the direction of the external auditory canal, the tympanic membrane will become inverted over time. In addition, rhinitis, pharyngitis or cold nasal congestion can cause Eustachian tube disorders and imbalance the pressure inside and outside the eardrum.

Therefore, keeping the eustachian tube open is key to preventing the tympanic membrane from invagination. Invagination of the tympanic membrane should be symptomatic**. If you have catarrhal otitis media or rhinitis, you need to treat these diseases first.

Eustachian tube blow-up may also be done, which requires a doctor. You can also use the "pinch the nose and puff up" method, close the mouth firmly, pinch the nostrils tightly, and make a puffing action, so that the gas does not escape from the mouth and nostrils, and the gas rushes into the eustachian tube, so that the tympanic membrane invagination can be restored. If you have a cold or acute upper respiratory tract infection, you should not use this method, so as to avoid accidentally blowing the nasal mucus mixed with bacteria into the tympanic cavity from the nasopharynx and causing acute inflammation of the middle ear.

At this time, it is necessary to use this method after a cold and acute upper respiratory tract infection, at least after taking medicine and disposing of it reasonably. Therefore, deaf patients should prevent the tympanic membrane from inverting, and once the tympanic membrane is inward, it should be active, and it is not difficult.

If it is a sudden hearing loss, you should go to the hospital as soon as possible** without delay. There are many people who can't recover their hearing because they don't have time**, and finally they can only choose hearing aids.

The human ear's receptivity to sound ranges from 16 Hz at low frequencies to 20,000 Hz at high frequencies. This is indicated on the diagram that examines the hearing. The frequency of normal human hearing is between 500 and 2000 Hz, and sounds above 2000 Hz are called high-frequency sounds, and sounds below 1000 Hz are low-frequency sounds.

A drop in high frequency means that your ears are less sensitive than normal when they receive high-frequency sounds, which means that you need to be louder (decibels) to hear. High-frequency loss generally indicates that the hearing loss is predominantly neurological, that is, neurological hearing loss. But as I said earlier, if it is a physical examination, these are not important, mainly depends on whether the applicable hearing is normal, and for the high-frequency drop, it also depends on the degree of decline.

Prevention first, usually pay attention to listening to ** with headphones as little as possible, answering **, not going to or going to less noisy public places, such as KTVPay attention to exercise, colds can also cause hearing loss. It's also important to maintain a good mindset.

Tinnitus is often accompanied by anxiety and depression, etc., which should be timely and standardized, and relieved as soon as possible to prevent the disease from prolonging. In addition, try to be optimistic, relax your mood, eat lightly, avoid spicy and greasy food, do not drink strong tea and coffee, and do not stay up late.

It depends on whether it is related to the working environment, and if the noise environment is not properly protected, it may still lead to hearing loss.
