Deafness, as a common ENT disease, can be clinically divided into two types, namely congenital deafness and acquired deafness. Although both are deaf, there are obvious differences between the two.

Congenital and acquired deafness can be judged based on the time when the deafness occurs.

1. Congenital deafness mainly refers to hearing impairment that occurs at birth or shortly after birth. According to different causes, it can be divided into two categories: hereditary and non-hereditary. The causes mainly include genetic factors, the mother's use of special drugs during pregnancy, the mother's illness such as gonorrhea, syphilis, and AIDS during pregnancy, and fetal head trauma caused by the use of forceps during delivery.

How is congenital deafness caused?
Congenital deafness, as the name suggests, is caused by congenital factors. It is related to genetic factors such as genes and the impact during pregnancy. Deafness genetic testing can be performed during pregnancy. Screening to find out whether there is a possibility of deafness in the fetus so that treatment can be carried out.

In addition, the first 3 months of pregnancy are a critical period for the development of the fetus's inner ear. If a pregnant woman is infected by a virus during this period, it may hinder the normal development of the fetus's inner ear and cause congenital hearing loss. . If diabetes, nephritis, thyroid dysfunction or even drug toxicity occurs during pregnancy, it may affect the hearing of the fetus, so attention should be paid to newborn hearing screening.


2. Acquired deafness mainly refers to hearing impairment caused by various factors after birth. The causes are mainly divided into sudden loud noise or long-term noise factors. Long-term hearing loss Stress influencing factors, drug factors such as aminoglycoside antibiotics, anti-tumor drugs, diuretics, anti-inflammatory analgesics, disease factors such as otitis media, acoustic neuroma, otosclerosis, sudden external attacks, etc.
The main factors causing acquired deafness are the following:
1. Noise factor: Sound damage to hearing is mainly divided into two categories: one is sudden loud noise, such as setting off firecrackers; the other is The first type is chronic noise. If you work under high noise for a long time, your hearing will be harmed unknowingly.
2. Stress factors: Stress is likely to cause sudden deafness, which is a type of neurological deafness, mostly in one ear.You can no longer hear your ears, and may be accompanied by tinnitus and a feeling of fullness in your ears.

3. Drug factors: Drug-induced deafness ranks first among the common causes of acquired deafness. About 30,000 people suffer hearing loss every year due to improper use of drugs. There are about 90 kinds of ototoxic drugs in clinical practice, the most common ones are aminoglycoside antibiotics, and others include anti-tumor drugs, diuretics, anti-inflammatory analgesics, etc.

4. Age factor: When people are around 60 years old, about 30% of people will have hearing difficulties with high-frequency shrill sounds; when they are around 80 years old, 50- 70% of elderly people have high-frequency hearing loss. In addition, the elderly are prone to diseases such as arteriosclerosis, hypertension, diabetes, and hyperlipidemia, which indirectly lead to lesions of the inner ear and ear nerves. These diseases can be treated to delay hearing loss.

5. Disease factors: Otitis media, acoustic neuroma, otosclerosis, etc. are all diseases that may directly lead to hearing loss. Through early treatment, most people can avoid deafness.
6. Traumatic factors: It is no joke to make a child deaf with a slap. The ear canal is very thin. If the high air pressure caused by slapping hits the eardrum directly, it can damage the eardrum and ossicular chain, causing deafness.

It is recommended that if patients have symptoms of discomfort, they should go to the hospital in time to make a clear diagnosis and choose an appropriate treatment plan under the guidance of a doctor.

You should also pay attention to some conditioning methods in your daily life to avoid affecting your hearing. Women should not blindly use some drugs during pregnancy, and they should pay attention to health care matters to avoid affecting their health. There will be more pain. I hope everyone will recognize this disease as soon as possible and stop blindly picking out their ears.
