My child suddenly can't hear clearly, what's going on?

Suddenly, the child cannot hear clearly. This not only happens to adults, but also to children. This makes many parents very worried and they want to find out the cause as soon as possible. Only by finding out the cause can they receive targeted treatment in the hospital. So, what exactly is going on when a child suddenly cannot hear clearly? The following is a detailed answer for everyone.

What's going on when my child suddenly can't hear clearly?

1. Inner ear microcirculation disorder: When a person is emotionally excited or anxious, the secretion of adrenaline increases, causing spasms in the small arteries of the inner ear. The blood flow in the small blood vessels slows down, causing red blood cells and platelets in the blood to stick to each other, resulting in blood circulation disorders. Insufficient oxygen supply to the inner ear leads to sudden deafness.

2. Viral infection: The virus has a strong affinity for the red blood cells and auditory nerves in the inner ear blood vessels. Many patients have a history of colds before the onset of the disease. When the virus invades the inner ear, it becomes affinity with the red blood cells and platelets, agglomerates into clusters, blocks the inner ear blood vessels, and causes sudden deafness. Sudden deafness is not as simple as getting angry.

3. Labyrinthal membrane rupture: Labyrinthal membrane rupture refers to the rupture of the round window or oval window membrane of the inner ear combined with rupture of the cochlear duct membrane. Due to the rupture of the membrane, symptoms such as sudden sensorineural deafness, vertigo and tinnitus occur. Sudden changes in middle ear pressure and intracranial pressure due to sudden exertion or experiencing a sudden change in air pressure. The mechanism by which this pressure change causes labyrinthine membrane rupture can be understood from two aspects.

4. Vascular lesions: Vascular lesions play an important role in the pathogenesis of sudden deafness. Due to vasospasm, embolism, thrombosis, vascular compression, intravascular stenosis, hemorrhage, increased blood coagulability, fluctuations in arterial blood pressure and other vascular disorders, the sensory structure of the spiral organ degenerates due to lack of oxygen. Except for those with vasospasm, the prognosis of others is poor, often resulting in permanent deafness. The cochlea has a very weak tolerance to oxygen. After 60 seconds of oxygen deprivation, the cochlear microphonic potential and nerve action potential disappear. If the blood flow is blocked for 30 minutes, although the blood flow is restored, the cochlear potential cannot be restored. Its pathophysiological mechanism is pathological intravascular red blood cell aggregation → increased blood viscosity → decreased blood flow velocity → hypoxia → increased permeability, tissue edema, blood concentration, small thrombus formation → tissue damage.

What happens when a child suddenly can't hear clearly? The above content is a detailed introduction to this issue. I believe that now everyone should have a better understanding and knowledge of the reasons why children suddenly can't hear clearly. I hope that the above introduction can help many parents find out the cause of the disease and go to a regular professional hospital for examination and treatment in time.
