The neuritis of the auditory nerve, or cochlear neuritis of the auditory nerve, is a pathological disorder in the nervous system that leads to hearing loss. By nature, it is an inflammatory disease affecting the auditory nerve. What are some of the symptoms that can be recognized by this great discomfort and how is it treated?
Reasons for the development of hearing neuritis
Any hearing problems have a very clear source and very unpleasant consequences: the person loses the sharpness of the reactions, there are problems of a physical and mental nature. To avoid this, you need time to detect such violations in the body. If the source of the problem is neuritis of the auditory nerve, the symptoms, the treatment of which will be described further, first of all, you should figure out what can cause the development of this disease.
- The development of complications in the process of spreading infection. Usually it is the causative agents of SARS, rubella, flu.
- The proximity of the source of infection to the auditory nerve with meningitis or parotiditis (epidemic).
- Toxic effects on the auditory nerve due to prolonged use of antibiotics (especially monomitsin, kanamycin, neomycin, and some others), quinine, aspirin, and cisplatin.
- The effects of salt, mercury, lead, used in some industries, as well as alcohol and nicotine.
- Exposure to allergens.
- Traumatic brain injuries that cause swelling, impaired blood circulation, and thus the supply of the auditory nerve.
- Acoustic injury due to the sharp impact of loud noises.
Symptoms of neuritis of the auditory nerve
Usually, one ear is the victim of the disease - then it is called one-sided. Less commonly, the inflammatory process covers both ears. In this case, bilateral neuritis is diagnosed. The defeat of the auditory nerve is accompanied by a number of symptoms that make it possible to judge the degree of progression of the disease:
- developing dysfunction of hearing, up to complete loss;
- noise or tinnitus;
- high blood pressure;
- shakiness while walking.
However, as a rule, the most pronounced manifestation of cochlear neuritis is hearing loss. The remaining symptoms appear depending on the activity of the inflammatory process.
Tactics of treatment of neuritis and manifestations of hearing loss
If neuritis is neglected, hearing loss may develop. Before you talk about the tactics of treating hearing problems, you need to find out what it is - hearing loss. This is the name of one of the consequences of the development of neuritis, manifested in the violation of sound perception - one of the ear systems. The hair cells take mechanical vibrations and transform them into a pulse transmitted to the brain as a sound signal. Hearing loss slows down the processes of sound perception - this is a symptom of the disease. The causes of difficulty in hearing are similar to those that provoke the development of neuritis, but there are also unrelated to it: congenital defects, heredity and changes associated with older age.
Treatment of hearing loss and cochlear neuritis is carried out according to a separate scheme for each specific cause of the disease. A thorough examination of the patient by the therapist, neuropathologist and otoneurologist is envisaged. Only after collecting a detailed history of the patient, the nature of the disease is concluded and treatment is prescribed.
Drug therapy can combine diuretics, anticoagulants, antispasmodics, antibiotics, antihistamines and detoxification drugs, as well as sedatives.
- In the event of a vessel malfunction, trental and Cavinton are prescribed driply (the dose is increased by 10 mg each of 10 infusions);
- Allergic manifestations are treated with antihistamines, developing a regimen of administration depending on the severity of the disease and the individual tolerance of the remedies;
- If the cause of hearing loss in an infectious disease, then antibiotics are prescribed.
As a rule, treatment is carried out by a course from 10 to 14 days. For this period of time, a salt-free diet and limited fluid intake are recommended.
Age and genetic causes of hearing loss are thoroughly investigated. You can weaken the age-related manifestations of cerbolysin, encephabol or nootropil. However, drug therapy or even surgery is ineffective. In this case, as a rule, a complete cure is impossible. Therefore, patients suffering from acute hearing loss are advised to wear hearing aids.
Symptoms and treatment of the auditory nerve neurinoma
Another problem associated with the perception of sounds is a neuroma that affects the auditory nerve. The structure of the nerve, providing the perception of sound, includes three parts: the cochlear, upper and lower vestibular. Neurinoma, being a benign, resectable tumor, develops in the vestibular regions. The possible risk factors for the development of this disease are not known to the medicine. Developing, the tumor begins to squeeze blood vessels and provoke the following manifestations:
- hearing loss;
- noise in the affected ear;
- frequent dizziness;
- instability when walking;
- tingling in the face (when the neurinoma grows and affects the facial nerve).
These symptoms are similar to the manifestations of neuritis, so for accurate diagnosis usually use NMR (nuclear magnetic resonance) and computed tomography.
The most effective methods for treating tumors are:
- surgical intervention;
- gamma knife therapy.
To select the tactics of dealing with a tumor, its growth is monitored. Especially it concerns those cases when the patient has reached old age or the neuroma gives about itself to know the minimum manifestations.
Radiation treatment consists of using a gamma knife, which allows the tumor to be irradiated, directing its action as precisely as possible to the neurinoma focus using a computer.
Surgical treatment is a cardinal method of dealing with a neuroma, used in case of a lesion of the facial nerve or the threat of deafness. The operation includes not only the incision, but also trepanning of the skull, and the period of final recovery may be delayed for a year.
Neuritis of the auditory nerve, the symptoms, whose treatment is determined on time, has favorable prognosis. If the disease is a consequence of infection, then deafness can be avoided. In the case of age-related manifestations of the disease with proper treatment may suspend the process of hearing loss. Neuritis, arising as a consequence of injury, can be partially or completely cured depending on the severity of the damage to the auditory nerve. In this case, any treatment should be prescribed by a doctor and carried out in a medical institution.
Hearing problems give a lot of inconvenience, but many of them are solved in one course of treatment and are characterized by a very favorable prognosis. The main thing - without delaying, consult a doctor who will prescribe a treatment for the neuritis of the auditory nerve, focusing on its specific causes. And in order to reduce the risk of recurrent illness, preventive measures will have to be taken: to treat infectious diseases in a timely manner, not to take antibiotics without consulting a doctor, to minimize contact with toxic substances and to avoid the constant effects of noise and vibration.
