General information about a disease
It is pathology of an internal ear at which the acoustical nerve suffers that affects sound perception. There is a damage of sensitive nervous sections of an acoustical nerve, internal ear and the central formations of an organ of hearing. ENT specialists in abbreviated form call NST disease. A synonym is the term "sensonevralny relative deafness". Some doctors as the diagnosis can write – "neuritis of an acoustical nerve" or "cochlear neuritis" - but it will not be absolutely right, after all the suffix "ит" indicates existence of an inflammation, and at this pathology as that it is not present. Long-term researches and the modern methods of diagnostics which appeared in an arsenal of physicians show that NST is a defeat of a kortiyev of body (the receptor part located in a webby labyrinth of the acoustic analyzer) and a back of the eighth nerve, and also the central and peripheral departments of a vestibular mechanism. Violation of a venous phase of blood circulation, microcirculation factors was revealed (vascular and intra vascular). It is stated gidrops a labyrinth, it in turn leads to violation of a metabolism of nervous fibers and a neuroepithelium. Conclusions were drawn that for successful treatment of neurotouch relative deafness it is necessary to stabilize cellular membranes, to improve venous outflow from a cranial cavity, to carry out dehydration. At a disease allocate three clinical forms:
- The sharp – prescription about four weeks. The success of treatment averages from 70 to 90% if it is begun in time.
- The subsharp – a disease lasts of a month to three. Here already efficiency of therapy from 30 to 70%.
- The chronic – pathology lasts more than three months. Efficiency of treatment sharply falls.
Why there is a neurotouch relative deafness?
The consensus about the reasons of development and progressing of sensonevralny relative deafness in physicians is not present so far. They only defined the factors playing a role in its emergence:
- vascular frustration (, cerebral , vertebrobazilyarny distsirkulyation);
- infectious diseases, such as , , , syphilis;
- acoustic, mechanical and barotraumas;
- work on noisy production, frequent vibrations;
- stressful states;
- influence of harmful household and industrial substances;
- by-effects from reception of some drugs ( belonging to aminoglikozida, some salycylates, antimalarial and diuretichesky means);
How the disease is shown?
The main symptom which has to guard the person is a deterioration of hearing (sudden or gradual). Process can be as one - and bilateral. One patients complain also of peep, a ring, "buzzer" in an ear are manifestations of high-frequency noise. And at other people deterioration of hearing is followed by a constant rumble (low-frequency noise). Besides, deterioration of hearing often is followed , , vomiting. If are available also vestibular violations, that is deviations in coordination of movements. All this has to push the patient immediately to register in reception to the otorhinolaryngologist.
Having come to the doctor, at first tell him that disturbs you. Explain, what events occurred before the sound perception worsened. At suspicion on neurotouch relative deafness the doctor will carry out kamertonalny tests to reveal – air or bone conductivity suffers at the patient. The voice-frequency threshold audiometriya will allow to specify the diagnosis, to learn extent of decrease in hearing. The plan of further inspection can include an impedansometriya – this method is directed on identification in a drum cavity of existence of an exudate (liquid), a rupture of a chain of acoustical stones, violations of functionality of an acoustical pipe.
Recommendations about treatment
For each patient the individual plan of treatment is formed, it depends on the reasons which caused a disease from its duration. Treatment of neurotouch relative deafness should be carried out in the otorinolaringologichesky hospital specialized, equipped with modern devices. Procedures have to begin immediately as soon as the patient came to a hospital. It is desirable to adhere to the sparing diet during treatment, to refuse , .
To improve blood supply of an internal ear, a brain Kavinton (Vinpotsetin), Tserebrolizin, Pentoksifillin, Piracetam appoint. In the first ten days they are entered into a vein. Then they can be entered into a muscle. After an extract will recommend to the patient to drink them in the form of tablets. Such preparations as Cinnarizine, Fezam, Nootropil (tablets or capsules) and Semaks (in the form of drops nasal) promote improvement of supply with blood and oxygen of organs of hearing and departments of a brain, these are so-called nootropa. Still these drugs improve protective properties of cages of sense organs, nervous cages, showing neurotyre-tread action.
If NST is followed by dizzinesses, write out the drugs having specific impact on an internal ear. Betagistin, Betaserk treats this group.
If the impedansometriya showed that in a drum cavity the exudate (such more often happens at an inflammation) collected, the patient should accept some time the preparations helping to remove excess of liquid from an organism (usually it is diuretics), and also antibacterial means.
For prevention of neurotouch relative deafness people which work is connected with noisy production, periodically should accept courses Tanakan.
Efficiency of medicamentous therapy can be increased significantly, appointing:
- 10 sessions of reflexotherapy (a lazeropunktura, acupuncture) with the subsequent repetition of courses;
- hyperbaric oxygenation (sessions for 30 minutes) – in special conditions under pressure to the patient moves for breath the mix containing a large amount of oxygen;
- phonoelectrophoresis, flyuktuiruyushchy currents.
If after a course of treatment of neurotouch relative deafness of desirable effect does not come, the hearing remains lowered, the doctor-audiologist for the purpose of correction of sound perception selects to the patient . You should not hesitate of people around and to be anxious because of it, after all modern devices differ in the small sizes, high sensitivity, they are convenient in use.
Achievements of a modern otokhirurgiya allow some patients to perform the operation called by cochlear implantation. Such operation helps at whom function of a kortiyev of the body which is responsible for perception of external sounds of environment by means of voloskovy cages is broken. If the nerve did not suffer then in an internal ear it is possible to implant special electrodes which will stimulate further directly an acoustical nerve. After similar implantation perhaps considerable restoration of hearing.
The people who transferred neurotouch relative deafness should take measures to secure itself against recurrence of an illness. Protect the ears from acoustic injuries (sharp loud sounds), try to avoid psychoemotional stresses, . Become tempered, strengthen immunity to pick up less diseases of the infectious and virus nature.
At sudden deterioration of hearing it is necessary to come to an appointment as soon as possible. If the patient postpones this visit, self-medicates, the probability to keep normal perception of sounds considerably decreases.
