Hearing impairment



People working in a noisy environment can develop hearing loss as a work-related problem. The noise level from woodturning can easily exceed 90 decibels, which is the level that can cause hearing loss. Therefore, if you are working in such environments, it is important that you wear earplugs.

An increasing number of young people develop hearing loss with the use of MP3 players and other devices. The volume on many headphones can exceed 90 decibels, so it is important not to listen to music in this way for an extended period of time and to have breaks in between. Noise from motorcycle gangs, which are popular these days, can also affect hearing and should therefore be avoided.

Children can often develop otitis media, or inflammation of the middle ear, due to a cold, which can affect hearing. Chronic colds should receive the attention of an ENT doctor.

Age-related hearing loss can be caused by chronic diseases in adults that lead to a decline in hearing function. It is important to maintain healthy blood pressure, exercise regularly, avoid excessive stress and fatigue, get enough rest, and limit consumption of coffee, coca and tobacco, as well as neuroexitants. and salt.

People with hearing problems should tell their doctor to avoid drugs that can affect hearing.

Hearing loss due to stress Acquired hearing loss has a variety of causes. In children, acute or persistent ear infections can cause conductive hearing loss, while in adults, chronic otitis media can cause conductive hearing loss with discharge from the ear. Causes of sensorineural hearing loss include sudden hearing loss, noise-induced trauma (noise-induced hearing loss), injections of antibiotics and other ototoxic drugs, Ménière’s disease with severe dizziness, otitis interna, acoustic tumors and others. Age-related hearing loss is a very common cause.

Stress-induced hearing loss can be divided into sudden hearing loss and Ménière’s disease. To prevent such stress-induced hearing loss, it is important to minimize stress. However, if sudden hearing loss, dizziness, muffled hearing and tinnitus, or ringing in the ears occurs, you should seek medical attention immediately. Sudden hearing loss is best diagnosed and treated within a week of onset.

Sudden hearing loss

Patients with “sudden hearing loss with tinnitus after waking from sleep” are the most likely to have sudden onset hearing loss. Sudden-onset deafness is sensorineural hearing loss that occurs acutely over a few hours or 2-3 days, of which a third of cases occur when the patient wakes up in the morning and can occur with ringing in the ears and dizziness. . Various causes can be the cause, and although it is difficult to identify the exact causative agent, it can be from an invasion of the acoustic nerve by a viral infection or from a blockage of the vessels of the cochlea. Stress is considered to be another cause of sensorineural hearing loss. Other causes include trauma or ototoxic agents and, in rare cases, a tumor that puts pressure on the acoustic cranial nerve. Therefore, appropriate tests should be performed to identify the cause.

It is difficult to predict the prognosis, but about half of these patients recover their hearing function within a few days. People with severe hearing loss accompanied by dizziness often have a harder time recovering.

Treatment usually consists of rest, steroid hormones, vasodilators to improve blood supply to the cochlea, and although the role of the drugs is not clear, they are known to aid recovery.

Sudden-onset hearing loss should be diagnosed and treated within a week of the event. Early diagnosis is crucial, so if you experience sudden hearing difficulties or muffled sounds, please go to the hospital to have a test for sudden onset hearing loss.

Ménière’s disease

Ménière’s disease, named after a French physician in the 1800s, refers to a group of symptoms including hearing loss, tinnitus, muffled hearing, and severe dizziness. Causes identified so far include autoimmune diseases, allergies, syphilis, otitis media, thyroid disease, and tumors, but in most cases the cause is not identified.

Autopsies of patients with Ménière’s disease showed an enlarged endolymphatic space in the cochlea, suggesting a role of abnormal endolymphatic secretion and absorption in the inner ear, causing endolymphatic edema, in the mechanism.

Dizziness, hearing loss and tinnitus

The cause of Ménière’s disease is often unidentified, so the diagnosis is made on the patient’s medical history. The characteristic dizziness complained of by these patients is spinning dizziness, where the patient or himself feels as though the environment or himself is spinning in circles, or by objects appearing to lean to one side. Dizziness lasts more than 20 minutes and resolves within 24 hours. It usually repeats itself and patients can have a normal life when they do not experience dizziness. When they experience dizziness, they often experience nausea and vomiting, as well as hearing loss, tinnitus, and a feeling of suffocation in the ears.

Patients often experience tinnitus with louder and louder sounds, and the muffled sensation is as if there is water in the ears before the dizziness begins. Hearing may decrease with dizziness, but usually improves when the dizziness subsides. However, with repeated episodes of dizziness, hearing loss gradually worsens and tinnitus may persist. About 30% of Ménière’s disease is bilateral.

Tests that can help in the diagnosis of Ménière’s disease include hearing tests and the test of vestibular function. To distinguish Meniere’s disease from a known cause, blood tests, x-rays, and MRIs may also be done.

Most are treated medically

Treatment options for Ménière’s disease include medical treatment, injection of drugs into the middle ear, and surgical treatment. Drug treatment consists of dietary changes such as a low sodium diet and the use of diuretics. It is reported that 60 to 70 percent of patients respond well to medications. Those who fail with this treatment may be given drugs in the middle ear to reduce vestibular function, or receive surgical treatment. The goal of treatment for Ménière’s disease is to prevent the recurrence of symptoms and to improve the symptoms that patients experience.
