Are there any types of deafness? What are the types of deafness?

Common types of deafness:

1. Conductive deafness: It is caused by the lesion of the middle ear of the outer ear, which hinders the sound conduction process. Common causes of deafness include foreign body in the external auditory canal, inflammation, congenital atresia of the ear canal, acute and chronic purulent otitis media, acute and chronic non-purulent otitis media, congenital malformations, and tumors.

2. Mixed deafness: there are lesions in both the sound transmission and sensory mechanisms. Such as long-term chronic suppurative otitis media, advanced otosclerosis, deafness, etc.

3. Sensorineural hearing loss: refers to the inability of cochlear spiral lesions to change sound waves into nerve excitation or the failure of nerves and their central pathways to excite and afferate nerves; or central lesions of the cerebral cortex that cannot distinguish speech, collectively referred to as sensorineural hearing loss. Such as Meniere's disease, poisoning, labyrinth, noise damage, acoustic neuroma, etc.

Hearing impairment due to a lesion of the cochlear spiral in the inner ear is called sensory hearing loss.

1. According to the location of the lesion, it is divided into:

1) Conductive hearing loss: hearing loss caused by sound wave conduction pathway disorders caused by lesions of the outer ear, middle ear and bone labyrinth;

Sensorineural hearing loss: hearing loss caused by disturbances in the acoustic wave perception and analysis pathway caused by lesions of the inner ear, auditory nerve, and auditory center;

2) Mixed hearing loss: both conductive hearing loss and sensorineural hearing loss.

2. According to the time of onset, it is divided into:

1) Congenital deafness (hereditary deafness and non-hereditary deafness).

2) Acquired deafness (acquired hereditary deafness and acquired non-hereditary deafness)3, which is divided into pre-verbal deafness and post-verbal deafness according to the degree of language function development.

According to the location and nature of the lesion, it can be divided into three categories: conductive hearing loss, sensorineural hearing loss, and mixed hearing loss. According to the time of the lesion, it is divided into two categories: congenital deafness and acquired deafness.

Grading of deafness: mild deafness: no difficulty in hearing general conversation at close range, audiometer examination of pure tone and speech hearing threshold at 26 to 40 dB

Moderate deafness: difficulty hearing at close range, hearing threshold 41 55db, severe deafness: difficulty hearing loud speech at close range, hearing threshold 56 70db

Severe deafness: can only be heard by shouting loudly in the ear, hearing threshold 71 91dbTotal Deaf:

You can't hear the sound of shouting loudly in your ears, and the hearing threshold of pure tone hearing is more than 91 dbGuidance: Prevention of sudden deafness1

Patients with sudden deafness should recuperate at home and avoid exposure to noise or loud sounds. Keeping the home environment clean and tidy and the patient's mood is conducive to recovery. 2.

To prevent colds, some patients with sudden deafness may be indirectly related to colds, so preventing colds can reduce a hair element. 3.Be careful not to overexert yourself, do your daily life sometimes, and eat a certain amount of food.

This disease is more common in middle-aged people, so middle-aged people should pay more attention to this. 4.Emotional stability, avoid anger and ecstasy, because these can make the human body nervous and humoral regulation out of balance, resulting in ear blood circulation disorders, deafness.

Classification of deafness. Depending on where and what nature of deafness occurs, deafness can be classified into different types.

Conductive hearing loss. Sound waves coming in through the air are blocked by lesions in the outer ear and middle ear, which is a mechanical conduction problem, and it is difficult for sound to move from the outer ear to the eardrum and middle ear bone. For example, otitis media.

Perforation of the tympanic membrane. Otitis externa.

Cerumen plugging. and so on, all of which can cause conductive hearing loss.

Sensorineural hearing loss.

Organic lesions or metabolic disorders of the cochlea, auditory nerve, or auditory center can lead to abnormal transmission of sound information, resulting in hearing loss or loss. For example, aging, noise hurts the ear, and deafness is caused by the ototoxicity of some antibiotics, diuretics and other drugs.

Mixed deafness. Lesions of the middle ear and inner ear coexist, and mixed hearing loss can affect both the auricular and sensory systems due to one disease, or it can cause problems in both systems due to multiple diseases.

Functional deafness. It is also called psychological deafness, non-organic deafness, mental deafness, etc. It is mainly caused by psychiatric and psychological factors, and most patients have a history of psychological trauma.

Pseudo-deafness. The patient has no abnormalities in the auditory system, is pretending to be deaf, and needs to be identified by audiological examination.

Classification of deafness: It can be divided into three categories according to the location and nature of the lesion. Conductive hearing loss:

The sound transmission mechanism of the outer ear and the middle ear is diseased, and the transmission of sound waves to the inner ear is impaired, such as deafness caused by earwax embolism and otitis media; Sensorineural hearing loss: refers to cochlear spiral disease, which is unable to convert sound waves into nerve excitation or dysfunction of nerves and their central pathways, and fails to transmit nerve excitation; Mixed hearing loss: co-existence of pathologies in both sound transmission and perceptual mechanisms.

Deafness is divided into: conductive hearing loss, sensorineural hearing loss, and mixed hearing loss.

Conductive hearing loss, sensorineural deafness, mixed hearing loss.

Deafness is congenital, may be subject to neurological accidents, and acquired, such as being deaf due to oppressive blows, but some are the possibility of **, the current medical technology is still good, if you have that kind of disease, you can try it, don't give up the opportunity.

According to the nature of the lesion, it is divided into two categories: organic deafness and functional deafness, the former refers to deafness caused by abnormal structure of hearing organs and tissues, and the latter refers to deafness caused by decreased hearing function.

According to the location of the lesion, it is divided into three categories: transductive (conductive) deafness, sensory (neurotic) deafness, and mixed deafness Deafness caused by abnormalities in the outer ear and middle ear is transductive, and deafness caused by abnormalities from the inner ear to the auditory center is sensorient, and both are mixed deafness.

Conductive hearing loss (also known as "transverbal hearing loss"). A type of hearing loss caused by abnormalities in the structure of the auditory organs involved in the transmission of sound vibrations. Features are:

1) Hearing loss is greater at lower frequencies than at high frequencies. (2) There is a large gap between air-conduction hearing loss and bone conduction hearing loss. Most people can recover or partially improve their hearing through surgery or medications**, and wearing hearing aids can help.

Sensory deafness (also known as"Neurological hearing loss"), "perceptual hearing loss". Deafness due to congenital hypoplasia of the inner ear or lack of sound perception of the cochlea in the inner ear due to medications, diseases, or trauma. The treatment effect of this type of deafness is not good, and the hearing loss is generally more severe than that of transliterative deafness, more than 70 decibels.

This type of deafness can be clearly visualized on an audiogram of bone and air conduction.

According to the time of the lesion, it is divided into two categories: congenital deafness and acquired deafness, and fetal deafness caused by various factors from pregnancy to delivery is congenital, and deafness that occurs after birth is acquired. From the perspective of the impact of lesions on children's language formation, it can also be divided into two categories: pre-learning (before 4 years old) deafness and post-learning deafness.

Pre-speech deafness: Deafness that occurs at birth or shortly after birth (before 4 years of age). Because they can't hear others, they can't learn speech and language like children with normal hearing.

The educational requirements for this type of deaf child are very different from those of deaf children after language formation, and usually focus on the acquisition of language and communication methods.

Hello, hearing loss is divided by nature:

Conductive hearing loss, sensorineural hearing loss, mixed hearing loss, and a non-organic hearing loss (a psychological problem).

These properties will be diagnosed by a professional doctor.

But hearing loss also depends on the degree of hearing loss.

According to 1997-WHO, the degree of hearing loss is divided into the following categories:

Average hearing loss of less than or equal to 25 dB is considered normal;

Mean hearing loss between 26 and 40 dB is considered mild;

Average hearing loss between 41 and 60 dB is considered moderate hearing loss;

Mean hearing loss between 61 80 dB is considered severe hearing loss;

Mean hearing loss of 81 dB or more is considered very severe.

It is recommended to go to a professional fitting center for specific consultation.

Types of deafness: conductive deafness, neural deafness, and mixed deafness.

Conductive hearing loss is usually caused by a disease of the middle ear in the external auditory canal. In the case of neural hearing loss, it is most often caused by cochlea, hair cells, and auditory nerves, as well as central lesions. Some patients may have both, which can be called mixed.
