neural deafness
Introduction
Introduction to neurological deafness Neurological deafness refers to a syndrome in which the auditory nerve of the inner ear and the auditory center of the brain occur, and causes hearing loss and even hearing loss, often accompanied by deafness. When neurological deafness is used, it actually refers to sensorineural hearing loss, including lesions of the cochlea, as well as lesions of the auditory nerve, and even some of the lesions of the central nervous system, not simply the problem of the auditory nerve. Different types of neurological deafness showed slight differences. The main manifestations were gradual hearing loss to unilateral or bilateral ear to varying degrees of deafness, accompanied by tinnitus and nausea in the ear. About half of the patients were accompanied by dizziness and nausea. And vomiting symptoms. In general cases, hyperbaric oxygen chamber treatment is available. For patients with deafness, vertigo, and tinnitus in the short term, high-dose shock therapy is used, and hormone therapy is used. basic knowledge The proportion of illness: 0.12% Susceptible people: no special people Mode of infection: non-infectious Complications: Alzheimer's disease
Cause
Cause of neurological deafness
1. Toxic deafness caused by continuous use of antibiotics such as streptomycin, kanamycin, gentamicin, etc. after illness.
2. Sudden deafness caused by viral infection or emphysema of the inner ear.
3. Contagious deafness caused by infectious diseases such as meningitis, measles and typhoid fever.
4. Detonation deafness caused by trauma or knocking or noise. Chinese medicine believes that the ear is the sputum of the kidney, perfused by the twelve meridians, and the brain is passed through. Its etiology and pathogenesis can be affected by wind and heat, liver fire, smoldering, kidney loss, spleen and stomach weakness. The clinical manifestations are mainly due to hearing impairment, loss or even disappearance. Children often have snoring or other various sounds in their ears, and the children feel more obvious in a quiet environment. May be associated with fever, headache, irritability, bloating, backache and other systemic symptoms.
Neurological deafness is a more complicated deafness disease. Neurological deafness is more difficult to treat than deafness in general. Because it is not just a problem inside the ear, it is also very likely to be related to the psychological factors of the patient. Therefore, in the treatment, if the patient does not have a positive state of mind, then even if the physiological disease has been completely solved during the treatment, the patient may still feel his own tinnitus. Although the symptoms are better than if you couldn't hear the sound before, it is still a heart disease. Therefore, in the treatment of neurological deafness, patients must actively cooperate and adjust their mentality to achieve the best results of treatment.
Prevention
Neurological deafness prevention
Bath bathing, anti-fouling in the ear to bathe, keeping the external auditory canal clean, is an important part of preventing ear disease. If the dirty water is in the ear, it can often cause pain in the ear canal, red and red swelling, and even perforation of the tympanic membrane. Therefore, when bathing, swimming, and shampooing, use clean cotton to block the outer ear canal to prevent water from entering the ear. When swimming in rivers and ponds, if the sewage is in the ear, clean the ear canal with clean cotton immediately, which can effectively prevent nervous tinnitus.
Stay away from noise
Long-term in the high noise environment of decibel, it will cause great damage to the auditory nerve of the ear and the central auditory nerve of the brain, and then induce the production of neurological deafness and tinnitus. In severe cases, the patient may be paralyzed. Therefore, away from noise, it is the most important prevention method of neurological deafness.
Enhance one's own constitution
Only with good physical fitness can the disease stay away from us. Therefore, in daily life, we must actively participate in various sports activities, pay attention to the daily diet adjustments, pay attention to rest, do not stay up late.
Pay attention to hygiene, quit ear
The ear canal hole is deep and the tympanic membrane is very thin. If you use hard objects such as iron, wood, bone, etc. in a crowded environment, it is easy to cause ear injury due to collision, and even tympanic membrane trauma, so that the ear canal Pain, bleeding, swelling, or hearing loss, leading to neurological tinnitus, so you need to quit ear habits.
Educate children to prevent foreign bodies from falling into the ear
Neurological tinnitus is more harmful to children than adults, mainly because the child's ear canal and tympanic membrane are relatively weak and vulnerable to ear disease. Therefore, parents should educate children not to put toys, beans, food, paper scraps and insects into the ear canal, so as not to cause external auditory canal inflammation, resulting in neurological tinnitus. If the ear canal is painful, hearing impaired, or even pus in the running water, it is necessary to check and clean the ear canal.
Entertainment is moderate, the volume is moderate
The tympanic membrane is very thin. If the volume is too large, it is easily damaged, causing neurological tinnitus and causing deafness. Therefore, the volume of the Walkman, MP3, TV, recorder, and audio should be moderate, and the tone should not be too high or too low. If the sound is transmitted into the ear, there is discomfort, even a pain in the ear, or affecting face-to-face conversation and upset, indicating that the volume is too large, should avoid, or reduce the volume. Wear noise-proof earplugs if you are working in a noisy environment for a long time, and check your hearing regularly.
In terms of diet, "two highs and two lows"
If you pay more attention to your diet, it can also prevent the occurrence of neurological tinnitus. Because the membrane of the patients with neurological tinnitus is mostly in the stagnant state, the physical and chemical properties of the endothelium are mostly low in sodium and potassium. Therefore, in the diet, the diet of two highs and two lows should be selected, namely high protein, high vitamin and low. Fat, low-salt diets, such as lean meat, fresh fish, live poultry and other stews, can also eat more fruits, leeks, carrots, celery and other high-vitamin vegetables and fruits.
Complication
Neurological deafness complications Complications, dementia
First, patients with deafness will have to repeat it at the beginning to understand the content of the speech. In order to avoid embarrassment when communicating with others, the listener may slowly isolate himself and cause depression. Children with neurological deafness often feel poor self-image due to low grades, and are prone to behaviors and psychological problems such as irritability and lack of concentration.
Second, deafness often gives patients unnecessary troubles than in life or employment discrimination, resulting in psychological inferiority, stress or depression, tolerance or reluctance to communicate with others, thus forming a personality Lonely, irritated, tempered and even more suicidal.
Third, there are many patients who know that deafness affects the development of the central nervous system, leading to atrophy of the auditory nerve, or the dullness of the hearing, and the brain's thinking will become slow.
Fourth, deafness can also make people's hearing ability lost, can not hear the voice in nature and the other party's conversation, but also reduce the ability of social activities to respond.
5. Sometimes deafness is often accompanied by tinnitus or rejuvenation, which makes some elderly patients' expression ability decline, leading to the lack of interpersonal communication in the elderly, which leads to unsociable and quirky, and may cause symptoms of Alzheimer's disease. .
Sixth, deafness will also appear in some newborns, which will make the newborn lose the ability to listen or speak from childhood, so that hearing loss, general hearing loss will also delay the normal development of intelligence and language of the newborn. Since newborns cannot obtain outside information from birth, the development of the language system is seriously affected.
Symptom
Neurological deafness symptoms Common symptoms Hearing loss Ear swelling, nausea, dizziness, central deafness, nausea and vomiting
Neurological deafness refers to a condition in which the lesion is located in the hair cell of the auger or the hearing of the hearing and the hearing loss caused by the conduction of the nerve impulse. All kinds of pre-existing factors that cause auditory nerve damage and hearing loss or total paralysis are neurological deafness. There are three main types: sensorineural deafness, conduction neuron deafness, and mixed neurological deafness. The clinical manifestations of neurological deafness are characterized by hearing loss or even disappearance. Patients often consciously humming or echoing various other periodic sounds. In a quiet environment, the patient feels more intense, obviously accompanied by a variety of systemic recurrent symptoms such as fever, headache, irritability, restlessness, bloating, and backache.
Neurological deafness symptoms: Hearing impaired hearing loss caused by lesions in the inner ear cochlear auger (the clinically known inner ear and basement membrane lesions are also summarized in the sensorineural deafness). Deafness caused by lesions in the nerve conduction path is called neurological deafness. However, it is often difficult to identify the difference between the two in clinical practice, so the two are often referred to as sensorineural-neural deafness symptoms. Therefore, clinically, all kinds of acute and chronic infectious diseases include ear infection, drug or chemical poisoning, labyrinthitis, membranous labyrinth, tibia fracture, acoustic neuroma, craniocerebral trauma, cerebrovascular accident, cerebral arteriosclerosis or spasm. Both deafness and senile deafness can be summarized in sensorineural deafness.
Examine
Neurological deafness examination
1. Blood routine and erythrocyte sedimentation rate Most patients have mild to moderate leukocytosis, about one-third of patients have eosinophilia, almost all patients have increased erythrocyte sedimentation rate, and some patients have increased reticulocytes and thrombocytopenia.
2. Immunological examination A small number of patients with rheumatoid factor, lupus cell positive, immunoglobulin and cellular immune test more normal.
X-ray chest radiograph shows enlargement of the left heart, enlargement of the whole heart, and sometimes heart failure changes. Electrocardiogram examination can be found in left heart hypertrophy, myocarditis, and arrhythmia. A small number of patients may have abnormal EMG. A gastroscopic or sigmoidoscopy can detect ulcerative changes.
Diagnosis
Diagnosis and diagnosis of neurological deafness
1. The disease needs to be differentiated from systemic lupus erythematosus, which has characteristic skin lesions, positive serum antinuclear antibody test, and Sm antibody, which is easier to distinguish.
2. When rheumatoid arthritis has ocular symptoms and the eighth pair of cranial nerve dysfunction, it is also easy to be confused with this disease, but rheumatoid arthritis has severe joint symptoms and many deformities, rheumatoid factor test. Positive, anti-nuclear antibodies are also mostly negative, the identification of the two is not difficult.
