Can a cold cause sudden deafness?

Sudden deafness, referred to as sudden deafness, refers to the sudden onset of tinnitus and deafness, with rapid hearing loss reaching a peak within hours or days. It mostly affects one ear, with a higher incidence in adults aged 40-60 years. Sudden deafness often occurs in the evening or when waking up in the morning. At first, you feel tinnitus in one ear, and a few hours later you notice sudden hearing loss. A few patients may be accompanied by vertigo, and in severe cases, nausea and vomiting may occur. The vertigo will gradually disappear within a week.

Can a cold cause sudden deafness?
People who have experienced colds account for more than 30% of all patients. Cold viruses easily enter the ears through the passage connecting the nasal cavity. The fragile ear nerves are easily infected by the virus and become inflamed and swollen. If not treated in time, you may suffer from sudden deafness.

Generally, there are the following factors that can cause sudden deafness
1) The human inner ear artery is an extremely tortuous terminal artery with no collateral circulation. When the human body is in a situation where adrenaline secretion increases due to emotional excitement, panic, etc., this curved and tiny ear artery may spasm, and the blood flow in the capillaries becomes slow or even stagnant, causing local ischemia and hypoxia. Insufficient oxygen supply to the inner ear causes sudden deafness.
2) Certain viral infections are also causes of sudden deafness.
Many patients with sudden deafness have a history of colds before onset. After the virus invades the inner ear, it combines with red blood cells and platelets, aggregates into clusters, blocks the blood vessels of the inner ear, and causes ischemia and hypoxia in the inner ear. In addition, the virus causes congestion and edema in the auditory nerve, causing damage to the auditory nerve and resulting in hearing loss.
3) Cervical spondylosis can cause sudden deafness

Long-term neck pain may indicate deafness. Deafness caused by cervical spondylosis may seem far away on the surface, but in fact the principle of its onset is quite simple. The ears are supplied with blood by a branch of the vertebral artery on both sides of the cervical spine. When there is a problem with the cervical spine, such as scoliosis, the vertebral artery will be affected, resulting in insufficient blood supply to the blood vessel branches assigned to the ears, which will lead to tinnitus and sudden onset of tinnitus. Deafness etc. At the same time, if the cervical facet joints are misaligned, it will also stimulate and compress the vertebral artery, reflexively causing spasm of the vertebral artery, reducing blood flow in the internal auditory artery, and inducing sudden deafness.

4) Blowing the air conditioner can also cause sudden deafness
When a person enters a low temperature room with an air conditioner from a high temperature outdoor, the sudden drop in temperature will cause hearing loss in the inner ear. Hypoxia, and when the inner ear is severely hypoxic, the inner ear capillaries will become necrotic. Once inner ear capillary necrosis occurs, sudden deafness will occur.

Generally speaking, young patients have stronger resilience. If the damage is not serious, they can fully recover by taking medicine. However, some patients only experience tinnitus without ear pain, so they ignore it. Even a year later, when the condition becomes serious enough to affect their daily life, they seek medical advice, but it is too late. Generally, the golden period for sudden deafness treatment is within 14 days, and the recovery rate is already low by 28 days. Therefore, if you experience ear discomfort after a cold, intermittent or persistent changes in hearing over a period of time, or frequent tinnitus, you should see an otologist promptly to check whether there is inflammation in the ear or conduct a hearing test to avoid irreversible hearing damage.

Sudden deafness occurs very suddenly. Patients often suddenly lose hearing sound in their ears after waking up or while eating. Many patients will suffer from ear plugs and tinnitus. Symptoms include: in mild cases, the sounds heard by the left and right ears are different, and the source of the sounds cannot be distinguished; in severe cases, the sounds cannot be heard.
