The harm and prevention of deafness

What are the hazards of deafness?

Jinghao hearing experts say that hearing impairment first brings difficulties to people’s work and life Communication:

(1) leaders and colleagues can’t hear the conversation clearly, and they are always worried for fear that others may misunderstand or affect their work;

(2) when family members talk to you, they often “ignore” and answer questions, which affects the harmonious atmosphere of the family;

(3) you can’t hear clearly when you call or watch TV, turn the volume on a lot, and make noise to your family and neighbors;

(4) the old people can’t hear it, the input of sound information into the brain is reduced, and the ability of the brain to distinguish sound information is reduced, which further aggravates the hearing barrier, which is manifested in the acceleration of speech speed, the brain is too late to distinguish and process the sound information, often hears the sound and doesn’t understand the meaning. In this way, the old people are more reluctant to communicate with others and listen less, which often leads to loneliness, depression or grumpiness of the old people, quality of life decline, and some are prone to Alzheimer’s disease;

(5) studies at home and abroad show that as long as children have mild to moderate hearing loss, it will affect their language development and intellectual development.

So we must care and protect our ears as we care and protect our eyes.

How to prevent deafness?

1. Jinghao hearing experts say that the same care is needed for the ears and eyes. The key to prevent deafness is to avoid the damage of various harmful factors to the hearing, such as banning and cautiously using various ototoxic drugs (such as gentamicin, kanamycin, streptomycin, etc.);

2. Avoid the damage to hearing caused by long-term noise and excessive detonation; actively prevent and control the infection of various bacteria and viruses to the ear.

3. For some high-risk groups with hearing loss, such as those with family history of deafness; workers exposed to strong noise for a long time; newborns with virus infection during pregnancy, etc., their hearing status should be checked and tracked regularly. Once hearing problems are found, rehabilitation treatment should be carried out as soon as possible, which will greatly reduce the occurrence and harm of deafness.

4. In case of existing hearing impairment, regular reexamination shall be carried out and corresponding treatment and rehabilitation measures shall be taken to prevent further aggravation of hearing loss.

What are the treatment and rehabilitation methods of deafness?

Drug treatment: in a short period of time after deafness, drug treatment such as improving inner ear microcirculation and hearing hair cell nutrition should be taken. Because the inner ear hair cells of sensorineural deafness are necrotic and exfoliated, they can’t regenerate. It’s not omnipotent to use medicine. The longer the deafness lasts, the less likely it is to be cured. If the sudden deafness can be treated with drugs 1-3 weeks later, the curative effect is not good if more than 3 weeks later.

Hearing aids: by far the most practical and effective means of hearing compensation and rehabilitation for patients with sensorineural deafness or loss of drugs and surgical opportunities.

Cochlear surgery: it is suitable for the patients with extremely severe deafness who are not effective in wearing hearing aids. Generally speaking, it is better for children under 5 years old and adults with post lingual deafness, but the cost is more expensive and the clinical application is limited.

Hearing and language training:

Generally, after wearing hearing aids, it doesn’t mean that a brand-new ear is installed. The hearing aid users need to have a brain auditory center to slowly relearn and exercise. According to the different degree of deafness and age and other factors, there needs to be a process of adaptation and training, which is summarized as follows:

Hearing training: after wearing hearing aids, deaf patients will gradually develop their listening habits and improve their abilities of hearing awareness, hearing attention, hearing understanding and memory.

Language training: train deaf children to speak, read, understand and accumulate vocabulary, master grammar rules, and express thoughts and feelings flexibly and accurately. Through the joint efforts of teachers and parents, deaf children can truly listen, speak, and be deaf without being dumb.
