I haven't heard jokes since I was a child.

Sudden deafness, also known as idiopathic sudden deafness or sudden deafness, is an emergency in otolaryngology. The patient's hearing was normal, and he couldn't hear the sudden sound without any warning. At first, he may only feel a "buzzing" sound in his ears, or feel that the sound is far away, and some patients are beginning to care. It was not until he answered the phone that he had to change his other ear to hear others speak, and then he suddenly realized that something was wrong because of one ear.

The main causes of sudden deafness are mumps virus (unilateral deafness), influenza virus, coxsackie virus and adenovirus. In addition, the internal auditory artery spasm or embolism caused by mental stress, excessive excitement, excitement, fatigue, alcohol and tobacco is also an important factor, which makes it difficult to supply blood and oxygen to the inner ear. In addition, severe coughing, sneezing, bending over, pinching the nose and inflating increase the pressure of getting lost (that is, the inner ear), leading to the rupture of the cochlear window membrane and deafness.

These all need to be prevented from life, such as preventing colds and regulating diet, but the prevention of genetic mutations needs to start from infants, such as the side effects of additives in children's snacks and the poisoning of automobile exhaust when taking children for a walk on the road, which can all be induced factors of genetic mutations. Most adults are related to mental trauma and excessive physical and mental fatigue. Don't let sadness, paranoia, depression and other psychological states and emotions interfere with life.
