Hearing Damage Due To Cold

Sudden hearing loss is a phenomenon in which hearing loss in one or two ears is rapidly lost due to damage to the auditory nerve - the hearing nerve. The rapid change of climate in the winter, the difference in temperature between day and night has led to a significant increase in the number of hearing loss patients in every country in the world. This is a disease classified as emergency in the otolaryngology specialty - hearing emergency.
Why sudden hearing loss?
Causes of sudden deafness are many, such as zonna virus, drug poisoning, inner ear hemorrhage, syndrome of increased internal pressure in the inner ear - Meniere's syndrome, nerve tumor VIII .

.. but it is thought that the cause The most common is due to vasomotor disorders of the blood vessels that nourish the inner ear (where the cochlea forms the hearing nerve).
This vasomotor disorder is common when the body is cold A decrease in body temperature causes the blood vessels in the body to shrink to heat, while reducing the perfusion of the organs it provides, including the hearing nerve which makes this nerve vulnerable.



if accompanied by favorable factors to coordinate such as the availability of chronic medical conditions mentioned above, are acute inflammation of the nose and throat, postpartum women, cold bath ...
Signs of hearing loss are often unclear
The warning signs before a patient has a sudden loss of hearing are not clear, and a 1-sided hearing loss even though it completely only reduces 12% of the total hearing capacity of the body so if the patient does not do the necessary jobs the subtleties of singers, musicians, etc., it will be difficult for them to detect their hearing impairment.
After recalling, patients said that before their sudden deafness, they felt empty and light-headed, accompanied by a migraine in the ear about to be deaf, unsteady and dizzy.
After a few hours, the patient hears tinnitus in the ears, the buzzing sounds at first sounds like a whistling wind then changes to like crickets in the ear accompanied by decreased hearing ability, the degree of hearing loss depends on according to each patient
Although not affecting lives, hearing loss greatly affects the quality of life.



Many patients with sudden hearing loss do not know, they skip the first 3 "golden days" can restore absolute hearing.
Observed on the frog's neurological microscope, it was found that nerve damage after 3 days hardly shows signs of recovery.
Prophylaxis and treatment of sudden hearing loss
Patients with sudden hearing loss often seek medical attention because of tinnitus in the affected party's ear and difficult sound direction, not because they feel the hearing loss there.
According to a study by Cambridge University scientists, people with atopic conditions, cervical spondylosis, suffer from certain medical conditions such as high blood fat, elevated blood uric acid, low blood pressure, and low blood pressure. high pressure ... are very susceptible to sudden hearing loss.




Especially when these subjects go out in the cold, especially after bathing in sports activities. Therefore, to protect hearing in the cold season, it is advisable to avoid going outside too early or too late, when the air is foggy, high humidity.

Deafness can recur suddenly, the next times will be worse than before or spread to the opposite ear, so patients who have the disease need to be placed under the close supervision of an ear, nose and throat specialist.
Patients with sudden hearing loss require prophylactic treatment in combination with wearing a hearing aid that stimulates the auditory nerve to prevent further deterioration of the nerve that causes progressive hearing loss.
At the same time learn more some systemic causes that can cause disease to combine treatment.



If the disease reappears, the detection time is important in prognosis. Medical treatment should be carried out immediately.
The current effective treatment regimen is absolute rest and infusion of antibiotics, anti-inflammatory, vasodilating, neurological vitamins, antiallergic drugs as well as sedatives for 10 - 20 days..
