The common symptoms of sudden tinnitus are as follows:

1. Tinnitus: more than 70% of patients have tinnitus when they are deaf, but tinnitus can also occur after deafness. People with severe deafness can wake up when they are asleep.

2. Deafness: before the onset of the disease, there are no signs, and a few patients have a history of mild cold, fatigue or emotional excitement. Deafness occurs suddenly and increases rapidly within 1 hour or 1 week. Some patients get sick in the morning or when they get up in the afternoon. If they have a sudden attack, they can hear a “shout” or “click” in their ears, and then they will feel deafness. Deafness is mostly on one side.

3. Vertigo: about 37% – 68% of the patients have vertigo of different degrees, of which about 10% can have severe vertigo with nausea and vomiting, followed by mild vertigo for up to 6 weeks. This symptom can appear at the same time with deafness, or before and after the occurrence of deafness.

4. A few patients may feel heavy and numb around the ears. The acoustic impedance was normal and showed normal tympanum pressure measurement curve.

5. Otoscopy: there is no foreign body in the external auditory canal, the tympanic membrane is clear and the mark is normal. The tuning fork test suggests sensorineural deafness.

6. Pure tone audiometry: the hearing damage is serious, and the hearing curve is of high frequency sudden drop type or total deafness sensorineural deafness curve.

7. Vestibular function test: the test results may be normal, decreased or completely disappeared by the combination of hot and cold alternation test and electronystagmography.

Experts pointed out that there are two main reasons for sudden tinnitus

1. Microcirculation disorder of inner ear: when people are excited or anxious, the adrenaline secretion of people increases, which makes the arterioles of inner ear spasm, and the blood flow in the arterioles is slow, causing the red blood cells and platelets in the blood to adhere to each other, causing blood disorder, and insufficient oxygen supply of inner ear leading to sudden deafness. Some old people, especially those with arteriosclerosis, are prone to sudden deafness due to the disturbance of blood circulation in the inner ear.

2. Virus infection: the virus has a strong influence on the red blood cells and auditory nerves in the inner ear blood vessels. Many patients have a history of cold before the onset of the disease. When the virus invades the inner ear, it dissolves with red blood cells and platelets, agglomerates and blocks the inner ear blood vessels, leading to sudden deafness. In addition, the virus and the auditory nerve affinity, can make the auditory nerve hyperemia, edema, but also cause sudden deafness.

Jinghao hearing aid experts remind: although some of the sudden tinnitus will be better, so many people are not satisfied with the sudden tinnitus, and have been dragging the disease, because of this, some people have not been treated in time and become permanent deafness, so the earlier the treatment of the sudden tinnitus, the better the effect.
