March 3 this year is the thirteenth National Ears Day. The theme is “Reduce Noise, Protect Hearing”. Who are the common people with noise-induced deafness? What are the manifestations of noise-induced deafness? How to prevent and treat noise-induced deafness?
Who are the common people with noise-induced deafness?
Noise-induced deafness is common in people working in high-noise environments, such as telephone operators and wireless workers who often wear headsets, riveters, blacksmiths, textile workers, naval engineers, tank pilots, aircraft field crews, dance halls and KTV workers.者 etc.
What are the manifestations of noise-induced deafness?
The main symptoms are progressive hearing loss and tinnitus, which have no obvious effect on ordinary speech. It was only found in audiometer examinations. Later hearing damage gradually developed to high and low frequencies, and finally decreased generally. At this time, hearing impairment is felt. In severe cases, it can be completely deaf. .Tinnitus and deafness can occur at the same time or separately. It is often high-pitched tinnitus, which is disturbing day and night.
In addition to hearing damage, noise can also cause headaches, dizziness, insomnia, high blood pressure, changes in electrocardiogram, and can also affect gastric peristalsis and secretion.
How to prevent noise-induced deafness?
How to treat noise-induced deafness?
There is still no real effective therapy, but early detection and early intervention are needed; treatments include cochlear vasodilators, ATP, vitamins, etc.Can be worn by patients with moderate deafness Hearing aid , Patients with severe deafness can undergo cochlear implant surgery.
What is a cochlear implant?
Cochlear implant, also known as electronic cochlea, is an electronic device that replaces the functions of the human ear. It can help adults and children suffering from severe and severe deafness recover or provide a sense of hearing.
Severe and severe deafness patients here refer to those whose binaural hearing threshold is greater than 75 decibels (dBHL) or above, and who wear high-power hearing aids are ineffective.Cochlear implant technology began in the 50s. After decades of development, especially with the emergence of high-tech such as biomedical engineering, it has moved from experimental research to clinical application and has become the only effective treatment for hearing loss in patients with total deafness. method.According to statistics, more than 5 deaf patients worldwide have used cochlear implants.
Which patients are suitable for cochlear implants?
For patients with pre-lingual deafness, in addition to regaining their sense of hearing, they must also learn language.Generally, the optimal age for implantation is under 8 years old, because 5 to 8 years old is the best time to learn language, and it is relatively difficult to learn language after 8 years old.Post-linguistic deaf patients do not need language training, and there is no age limit.
Of course, in addition to age factors, the patient should not have serious external ear and middle ear diseases and systemic serious diseases, and should also have a stable psychology, have a correct understanding of the effects of surgery, and be able to adhere to language and hearing training for a long time.
