What s wrong with deafness? What is deafness?

There are many causes of deafness, such as genetics, birth trauma, infection, improper use of drugs, immune diseases, physiological deterioration, and poisoning by certain chemicals. In addition, there are some cases where the cause of deafness is unknown.

Hello! What's wrong with deafness? There are many properties of deafness, which probably means that there is a problem with sound conduction, which makes it difficult for the brain to receive sound, and it is difficult to speak and communicate, and in severe cases, it is almost impossible to hear any sound. Hope mine helps you!

There are many kinds of deafness, and the specific factors are uncertain, and it is difficult to judge what causes it, and it varies from person to person.

Deafness is complex, with congenital and acquired factors, as early as possible.

I just can't hear clearly, I can't hear well.

There are many reasons for deafness, and it is generally impossible to **, mainly wearing hearing aids.

There are many reasons for hearing loss, so treat it as soon as possible

Deafness can be caused by many causes, and deafness needs to be followed as soon as possible.

It is recommended that it can be treated with traditional Chinese medicine.

Sudden deafness is also a relatively common symptom, which can also be called "idiopathic sudden hearing loss" in clinical practice, which mainly refers to the sudden occurrence of unexplained sensorineural hearing loss in the ear in ordinary life. In general, the main clinical manifestation of patients is hearing loss in one ear, and some patients will also be accompanied by tinnitus, ear congestion, vomiting, dizziness, nausea and other symptoms.

Disorders of the auditory nerve and centers at all levels in the auditory system, such as sound transmission, sensory and other auditory transmission pathways, can cause auditory dysfunction. This is what we call deafness. The causes of deafness are really varied, and it may be congenital or acquired trauma.

In our daily life, we can also find people with hearing impairment, some of whom are completely deaf, and some of whom are only hearing impaired and have hearing loss. The causes of these problems are also diverse, with both congenital and acquired factors. Among them, suppurative otitis media is the most important disease that causes deafness.

According to the location of the lesion and the growth of people, it can be divided into: conductive hearing loss, sensorineural hearing loss, mixed hearing loss and central hearing loss.

The most common congenital prehistoric congenital malformations include malformations of the outer ear and middle ear, such as congenital atresia of the external auditory canal and hypoplasia of the eardrum ossicle, cochlear window, vestibular window, etc. These are the most common congenital factors. These reasons can also be improved by the acquired **.

There are many reasons for the formation of acquired deafness. Such as cerumen embolism, bone warts, foreign bodies, tumors, inflammation, etc. Various acute infectious diseases, such as epidemic, Japanese encephalitis, mumps, measles, scarlet fever, and herpes zoster auricus, may cause sensorineural hearing loss to varying degrees.

There is also drug toxicity for deafness. Some people have a toxic reaction to the drug, which can also cause deafness.

There is also presbycusis, which is common in daily life, which is mainly due to arteriosclerosis and bone hyperplasia, insufficient blood supply, and hearing loss caused by degenerative changes. Deafness can occur if a head injury or fracture damages the inner ear structure, or if the inner ear is damaged by a strong vibration. There are other causes, such as sudden deafness, for unknown reasons.

The above are the more common causes in life, so the most common is not congenital deafness, then it is generally due to the phenomenon of deafness caused by intra-child infection. There is also the degenerative changes caused by living in the noise room for a long time, in the environment, or because of age. Many types of deafness can be improved with **.

Hello, what is deafness.

The deafness is complex, with congenital and acquired factors, among which purulent otitis media is the most important deafness disease in conductive deafness. In recent years, secretory otitis media has become the leading cause of hearing loss in children. According to the location and nature of the lesion, deafness can be divided into four categories:

That is, conductive hearing loss, sensorineural hearing loss, mixed hearing loss, and central hearing loss. Lesions occur in the auditory nerve and centers at all levels in the auditory system in the sound transmission, sensory and auditory conduction pathways, causing auditory dysfunction and varying degrees of hearing loss, collectively referred to as deafness. It is generally considered that when the average hearing threshold of speech frequency is above 26dB, it is called hearing loss or hearing impairment.

Depending on the degree of hearing loss, it is also called hard of hearing, hearing impairment, hearing loss, hearing loss, etc. Hope mine is helpful to you!

Deafness refers to the lesions of the auditory nerve and centers at all levels in the auditory system, causing auditory dysfunction and varying degrees of hearing loss. Deafness is not simply inability to hear, for example, patients with mild hearing loss have no problem in close communication in a quiet environment; However, in the case of severe hearing loss, most sounds cannot be heard.

Another example is that many patients will be able to hear sounds but cannot hear clearly, because after hearing loss, the person's ability to distinguish the time, frequency and intensity of sounds will be reduced, resulting in reduced speech recognition.

Various environmental pharmacogenetic factors.

Clause. 1. The most common is conductive deafness caused by otitis media or trauma, which is relatively easy to treat, and can be treated with drugs and surgery.

Clause. Second, inductive neural deafness, deafness is caused by sudden deafness, vasospasm or senile degeneration, it is not easy to **.

Clause. 3. Conductive deafness and sensorineural deafness are both, so it is called mixed deafness, and the factors that affect each other together need to be taken into account. There is a principle of deafness, the sooner the better, if the hearing is restored, it will have no impact on daily life, and it will not cause tinnitus or vertigo.

Clause. Fourth, because deafness is always related to the middle ear and inner ear, sometimes because of cerumen embolism caused by the blockage of the external auditory canal, it will also cause deafness, which is better, you can go to the outpatient clinic to ask the doctor to clean the external auditory canal, dredge the place that needs to be dredged, and the deafness can be recovered.

Depending on the nature of deafness, deafness can be divided into conductive deafness, sensorineural deafness, and mixed deafness. Some of these conditions of deafness can be recovered or improved with effective medical treatment**. For example, conductive hearing loss is mostly due to hearing impairment caused by lesions of the outer ear and middle ear, which can be restored or improved by medication, surgery and other means.

Sensorineural hearing loss is often caused by lesions of the inner ear and behind the cochlea, and most sensorineural hearing loss still lacks effective methods. For hearing loss that does not respond well or do not respond to formal medical treatment**, we would recommend a hearing intervention with a hearing aid device.

Optional hearing aids are currently the mainstay of treatment for most sensorineural and partially conductive, mixed (especially cochlea) hearing loss. The function of hearing aids is to amplify sounds, so that patients can easily hear very weak speech and ambient sounds, thereby helping patients communicate better and improve their quality of life.

Deafness can be inherited from congenital causes, as well as hearing loss or decline due to external environmental factors.

There are many types of deafness, such as cerumen blockage in the patient's ear canal, resulting in conductive hearing loss. It is recommended that the patient actively go to the hospital to clean the cerurumen, after which the patient's hearing will be significantly improved.

The loss of hearing is called deafness. Deafness caused by sound wave propagation disorders due to abnormalities in the outer and middle ears is called conductive hearing loss. Hearing impairment caused by abnormalities in the auditory receptors and auditory conduction nerves and auditory centers in the cochlea is called neural hearing loss.

Deafness can be caused by ototoxic drugs, congenital, noise, viral infections, bacterial infections, trauma, tumors, etc.

There are many causes of deafness: The following causes can cause deafness.

History of familial deafness.

History of other ear diseases: such as otitis media, Meniere's disease, etc.

Long-term exposure to noisy environments.

History of ototoxic drug use.

Chronic diseases: such as hypertension, hyperlipidemia, diabetes, autoimmune diseases, etc.

Bad habits: such as smoking, drinking, etc.

Long-term mental stress and excessive anxiety.

Unhealthy lifestyle: such as staying up late for a long time.

Common deafness falls into three main categories:

1. 14% of conductive deafness is conductive, the reason is that the outer ear or middle ear lesions lead to voice conduction disorders, which is commonly known as otitis media, which can generally be effective through drugs or surgery.

2. Inductive neural deafness, more than 70% of the deafness of the elderly group is due to senile lesions in the cochlear auditory nerve or auditory center, which are irreversible and cannot be passed by drugs or surgery**, but they can improve their hearing by wearing scientifically prescribed hearing aids and live the same life as normal people.

3. Mixed hearing loss, if the factors that cause conductive and sensorineural hearing loss exist at the same time, it is mixed hearing loss, which is more complex and needs to be treated according to specific cases.

There are many causes of deafness.

Classification of deafness: hereditary deafness, drug-toxic deafness, infectious deafness, sudden deafness, deafness with autoimmune diseases, presbycusis, auditory neuropathic deafness, deafness due to acoustic neuroma.

Deafness**: 1. The most common of them is infectious, that is, caused by inflammation of the outer ear or middle ear.

2. Otitis media is generally common, otitis media has purulent middle ear inflammation, usually with damage to the ossicular chain, resulting in conductive deafness; There is also secretory otitis media, which causes conductive deafness due to negative pressure in the tympanic cavity and fluid in the tympanic cavity, resulting in impaired activity of the ossicular chain.

Deafness refers to certain impairments of the auditory system, which are most common in older people. It is the aging of the organization of the auditory system, which leads to certain hearing impairments. The symptoms of deafness can generally be divided into four categories, namely sensorineural deafness, neural deafness, vascular deafness, and cochlear conductive deafness.

The symptoms of deafness are usually caused by both congenital and acquired factors.

First of all, some patients have deafness after birth due to parental genetic factors, that is, congenital chromosomal abnormalities, which is usually more difficult.

Secondly, the patient has suffered serious external damage to the ear or noise pollution, which has caused hyperacusal reaction in the ear, serious inflammation and infection in the ear canal, birth injury to the ear during birth, long-term use of ototoxic drugs and other factors, which may cause deafness.

There are many causes of deafness, such as genetics, birth trauma, infection, improper use of drugs, immune diseases, physiological deterioration, and poisoning by certain chemicals. In addition, there are some cases where the cause of deafness is unknown. From the occurrence of deafness.

Many factors, both congenital and acquired, can eventually cause deafness.

Congenital factors, including genetic factors and maternal infection during pregnancy and childbirth, often lead to hearing at birth and shortly after birth.

The loss of force, of course, can also be delayed.

Acquired deafness can occur at any age. For example, the risk of hearing loss increases as we age; environment or noise too.

large, exceeding the normal tolerance threshold; Noise pollution for a long time, etc.

First, hereditary deafness: deafness caused by a genetic or chromosomal abnormality carried by both parents, one of which is deaf and mute, and the dominant gene on the chromosome is passed on to the offspring, which is autosomal dominant deafness. If both parents have normal hearing but carry a chromosomal recessive deafness gene, the offspring will have recessive deafness, or be associated with hereditary deafness.

Second, non-hereditary deafness:

1. Pregnant 3-4 months mother suffering from rubella, mumps and other diseases, or recovering for a short time nephritis, hepatitis, diabetes or using ototoxic antibiotics such as gentamicin, chain, etc. or prolonged labor during labor, dystocia, birth trauma, neonatal hypoxia, asphyxia, neonatal jaundice, failed serum, preterm birth, and low birth weight children can cause deafness.

2. Presbycusis: This is the degenerative changes of the hearing organs caused by the aging process of the human body, as well as genetics and one's own health conditions. High blood pressure, hardening of the arteries, diabetes, coronary heart disease, and other chronic diseases can induce or worsen hearing impairment.

3. The root cause of infectious deafness: ** is the acute and chronic infectious diseases caused by various sensorineural deafness. For hearing loss serious infectious diseases are meningitis, scarlet fever, diphtheria, typhoid, rubella, influenza and mumps, measles, chickenpox, etc.

Pathogenic microorganisms or their viruses can enter the inner ear through the bloodstream, destroying its structure and causing unilateral or bilateral development or aggravation of sensorineural hearing loss.

4. Deafness caused by systemic diseases: Many systemic diseases cause deafness, but inner ear blood diseases caused by vascular diseases are very common, such as hypertension, arteriosclerosis, etc.

5. Toxic drugs for deafness: At present, more than 100 kinds of ototoxic drugs have been found, which can enter the fetus with the fetus during the placenta and affect the development of the fetal inner ear, and can also be deaf and mute people of all ages.
