Sudden deafness, sudden deafness, how much do you know?

Sudden deafness, which is mostly unknown, is related to the patient's systemic disease and mental state. Hearing loss is mostly moderate to severe sensorineural hearing loss, and high-frequency hearing loss decreases more. Most of them can heal on their own, or recover through **.

Therefore, hearing aids are not recommended for those with a short onset time (within 3 months). There is also permanent hearing loss or deafness, and the sooner it occurs, the better; If you can find out**, try to find out**. Usually take hyperbaric oxygen or hormones and other methods, it is specifically recommended to go to the hospital specialist to consult a doctor, and actively take **measures** to cooperate**.

If it has been more than three months,** there is no recovery, or there is still hearing loss, the doctor recommends hearing aids. You can choose the right hearing aid according to your hearing condition.

The theory of sudden deafness is unknown, and many agens may cause sudden deafness, and the main theories that have been widely recognized are viral infection, circulatory disorders, autoimmunity, and membrane labyrinth rupture. About 80% of patients with sudden deafness can recover their hearing within a week, and the effect is worse two weeks after the onset of the disease. There are foreign data that show that the course of the disease is more than a month, the hearing has been basically finalized, the effect of ** will be greatly reduced, you have to change your living habits, rest more, work and rest time should be normal, do not stay in a noisy environment for too long, if the hearing does not improve, you need to be equipped with hearing aids, which will inhibit your tinnitus.

Sudden deafness is an ear disease that is currently unknown in medical clinics, it is mainly based on internal medicine - doing hyperbaric oxygen, injections, and taking medicine, but its ** effect is not good, and the hearing improvement effect is not obvious, so we can only change some of our bad living habits, such as colds, staying up late, often going to places with very noisy environments like KTV, bars, long-term wearing of headphones, playing **, etc., will cause sudden deafness.

Continue**, hearing aids are also available.

Sudden deafness (hereinafter referred to as sudden deafness) is a sudden onset of unexplained sensorineural deafness, also known as violent deafness. Its onset is acute, the progression is rapid, and the effect is directly related to the time of consultation, so it should be regarded as an ear emergency.

**。Sudden deafness** is unknown, and more than 100 causes of the disease have been documented, many of which are rare. According to Mattox (1977), the causes of the disease are viral infections, vascular diseases, endolymphedema, rupture of the labyrinthine membrane, and a combination of the above.

Symptom. (1) Deafness. The disease is a severe one, with hearing loss occurring instantaneously, within hours, or over days, as well as sudden deafness in the morning.

In slow cases, deafness can gradually worsen and stop progressing after a few days. The degree ranges from mild to total deafness. It can be temporary or permanent.

It is usually unilateral, and occasionally both occur simultaneously or sequentially. It can be cochlear deafness or postcochlear deafness.

b) Tinnitus. Tinnitus occurs mostly before and after deafness, accounting for about 70%. It usually occurs a few hours before deafness, is usually a buzzing sound, and can last for 1 month or more. Some patients may emphasize tinnitus and ignore hearing loss.

c) Vertigo. About 2 5 days 1 2 sudden deafness accompanied by varying degrees of vertigo, of which about 10% are severe deafness, nausea, vomiting, can last for 4 7 days, mild dizziness can exist for more than 6 weeks. A small number of patients present with vertigo as the main symptom, which is easily misdiagnosed as Meniere's disease.

After a few days, it will be relieved, and it will not be reversed.

d) Ear blockage. Ear blockage usually precedes deafness.

5) nystagmus. If vertigo is present, there may be spontaneous nystagmus.

Examine. (1) Inquire about the medical history in detail. Patients with sudden deafness due to viral infection may have a clear history of influenza, colds, upper respiratory tract infections, sore throat, paranasal sinusitis, etc., or contact with a person infected with the virus, which can occur weeks before hearing loss.

Patients with sudden deafness due to vascular lesions may present with a history of heart disease or hypertension, as well as diabetes mellitus, arteriosclerosis, hypercholesterolemia, or other systemic disorders that affect the microvascular system. Patients with ruptured labyrinthine membranes often have a clear history of exertion, or experience changes in air pressure, such as difficulty urinating, defecation, coughing, sneezing, bending over, laughing, swimming, diving, diving with a sonic tube or scuba apparatus, or unusual flight activity.

2) Full body examination. It should target the cardiovascular system, coagulation system, metabolism, and immune reactivity. Neurologic examination should rule out lesions of the internal auditory canal and cerebellopontine angle, and vertebral basal and cerebral vascular circulatory disorders such as endoauditory tract and cervical spine radiographs, cranial CT scan, fundus and cerebral blood flow studies.

Wang Shuchun et al. examined the cerebral blood flow of 104 patients with sudden deafness, and found that the cerebrovascular function of patients with sudden deafness was worse than that of normal patients.

3) Laboratory tests. Including blood picture, erythrocyte sedimentation rate, coagulation time, prothrombin time, platelet count, etc. Serologic testing isolate the virus and measure antibody titers, and blood glucose, lipids, nitrogen, and serum syphilis tests may also be considered.

4) Otoscopy. The tympanic membrane is usually normal and may be reddish.

5) Hearing examination. Understand the nature, extent and dynamics of hearing loss.

6) Vestibular function examination. Electronystagmography if necessary.

Sudden deafness is a common type of deafness, if we lose the ear to hear the world, we lose the confidence in life, so the protection of the ear family Na Bang Duo is something that everyone should pay great attention to, so in order for everyone to stay away from the disease, let's take a look at what are the causes of sudden deafness?

1. Viral infection: Many scholars have noticed the inducing effect of mumps virus on the disease, and other diseases such as coxsackievirus and adenovirus are also related to the disease.

2. Vascular factors: such as endosicular artery spasm or embolism, can cause the nutrition supplied to the inner ear to be impaired and lead to the onset of the disease.

3. Rupture of the cochlear membrane: The cochlear membrane is ruptured, and the external lymph fluid flows out from the cochlear window, resulting in sudden deafness. The rupture of the cochlea may be caused by increased labyrinthine pressure during coughing, sneezing, bending over, pinching the nose and puffing up. It has been speculated that there may also be signs of vestibular membrane rupture.

Depending on the onset, the loss of force is sensorineural and a one-time hearing loss, whether it is ** or not, it can be gradually recovered or completely unchanged, and retrocochlear lesions should be particularly vigilant. Hearing loss in Meniere's disease is fluctuating, with hearing loss occurring at the time of seizure and recovery in remission, and hearing loss in recurrence, often repeatedly.

Sudden deafness has a great impact on our hearing worms, so if we find ourselves in these situations, we must actively carry out **, and the most important thing is to pay attention to the health of our diet, stay away from smoking, drinking and other unhealthy lifestyles, and eat more fresh vegetables and fruits in order to live a healthy life.

Sudden hearing loss, also known as idiopathic sudden hearing loss, refers to hearing loss that occurs suddenly and unexplained within 72 hours.

**: Viral infections, vascular diseases, neoplastic diseases, acoustic neuroma, intracranial tumors, drug poisoning, immune diseases, systemic lupus erythematosus, autoimmune diseases, ear and filial hand shed diseases.

Predisposing factors: It is generally believed that mental stress, high stress, emotional fluctuations, irregular life, sleep disturbances, etc. may be the main triggers of sudden deafness.

Sudden deafness is an acute disease of hearing loss, which often causes rapid hearing loss within 72 hours, and some are accompanied by tinnitus, stuffiness and other conditions, and the cause is unknown.
