Hearing loss caused by eardrum perforation can be recovered, generally speaking, eardrum perforation will affect the patient's hearing, perforation, the larger is that the patient may have the symptoms of conductive deafness, and there will be a phenomenon of air-bone conduction difference between the air lead and the bone lead on the audiogram during clinical examination.

The purpose of tympanic membrane repair is twofold: first, to close the perforated eardrum and prevent further reinfection; The second is to improve hearing. Suggestions:
Before the surgery, a subsidized test must be done to prove that the hearing can be improved, and the hearing function can be restored after the repair. 。

Can a perforated eardrum cause deafness.

Perforated eardrums affect hearing to varying degrees depending on the size and location of the perforation, but perforated eardrums alone do not cause total deafness.
The eardrum (tympanic membrane) is the barrier separating the external auditory canal and the middle ear, which is divided into three layers, the outer layer is the epithelial layer, which continues with the external auditory canal**, the inner layer is the mucosal layer, 95 continues with the middle ear mucosa, and the middle layer is the fibrous layer.
The conduction of hearing is that after the pinna collects sound, it is transmitted to the eardrum through the external auditory canal, and the tympanic membrane vibration is transmitted to the ossicular chain vibration of the middle ear, and the physical signal of the vibration is transmitted to the inner ear, which is converted into electrical signals in the inner ear hair cells, and then transmitted to the auditory cortex of the central nervous system through nerves, so that the brain perceives sound. Thus, a lesion anywhere from the pinna to the inner ear that results in decreased acoustic signal transmission manifests as conductive hearing loss. On the other hand, the inner ear lesions cause a decrease in the ability to convert electrical signals or transmit signals to the brain, which manifests as sensorineural hearing loss.
The integrity of the tympanic membrane is very important for sound afference, when the tympanic membrane is perforated, the vibration area of the tympanic membrane is reduced, and the sound transmission ability is naturally weakened, so the area of the tympanic membrane perforation affects the degree of hearing loss, the larger the perforation area, the more hearing loss, the location of the perforation also has an impact on hearing, and the closer the perforation location is to the auditory bone, the greater the impact on hearing. Small needle-like perforations or small perforations at the edges have very little effect on hearing. Conductive hearing loss caused by simple tympanic membrane perforation is mild to moderate, and if it exceeds this limit, it is usually accompanied by lesions of the ossicular chain of the middle ear or sensorineural hearing loss.

The impact on hearing, of course, will be great.

If the tympanic membrane perforation is greater than 1mm and is not carried out**, it may cause dirty water to enter the ear, such as bath water, shampoo or swimming, these dirty water entering the ear may cause middle ear infection, which can lead to a larger or more severe perforation, and even sensorineural hearing loss.
If the tympanic membrane perforation is relatively small, such as less than 1 mm, it does not require intervention, and even if water enters the ear, it will not enter the middle ear and will not cause infection.
For patients with tympanic membrane perforation, it is generally recommended to do it as soon as possible**, especially if the tympanic membrane is perforated relatively large, and the endoscopic method can be used without an incision and can be operated directly inside the ear.
If the introducer is a neighbor near your home or something, and there is a possibility that you will not look up and see you, then you will call the ** district to ask when you go back that day, and you must at least be prepared to be introduced to the number of people, because the introducer is likely to blame you for not knowing how to do things. However, there are many blind dates, and the numbness you feel is not difficult to understand. If you can ask earlier, there is a result, and you can be regarded as responsible for yourself. >>>More
It makes me a little confused, because I don't know how old you and your person are, what grade you are in, and your current situation is a confusion that many people have encountered when they were young, but things have changed, and after countless growth baptisms in life, they will think how naïve they were before. >>>More
After chemotherapy, patients with loss of appetite, indigestion and diarrhea can be supplemented with foods that strengthen the spleen and stomach, such as barley seeds, white lentils, jujubes, etc.
It is a normal phenomenon that the post-zero generation cannot afford to buy a house, and the post-zero generation is only less than 20 this year, how can they afford to buy a house? Housing prices are so expensive now! If you must buy a house, you may need to borrow a little from your parents and then apply for a loan from the bank, or rent a house outside first and wait until you have accumulated a certain amount of wealth before buying a house.
In planting good mulberry leaves.
On the basis of preparing the silkworm room and silkworm tools; 7 days before raising silkworms, spray and disinfect with 1% strong chlorine, half a kilogram of medicinal solution per square meter, seal for more than 24 hours after spraying, and at the same time, spray the surrounding environment of the silkworm house should be sprayed and disinfected. About the eighth day of silkworm seed out of the warehouse, you can see that there is a small black spot at one end of the silkworm egg, called point green, a silkworm seed has 20% of the eggs point green, use the black cloth to shade the light, from the day of the point of green, the black cloth will be removed at 5 o'clock in the morning of the third day, and the light will be turned on to incubate. >>>More
