Original title: Hearing loss is irreversible Be wary of these behaviors that can cause hearing loss
Today is the 25th National Day for Ear Care. The theme is: Technology Assists Listening, Sharing a Better Life. The purpose of this year's National Ear Care Day is to promote the scientific knowledge and methods of ear care and ear protection, guide the public to comprehensively enhance their awareness of hearing health, and advocate hearing health management throughout the life cycle.
Xiao Jiang, 25 years old this year, usually likes to listen to ** with headphones. During the Spring Festival, he suddenly experienced symptoms such as tinnitus and hearing loss in both ears after staying up late at home to play games for a long time.
When the doctor examined Xiao Jiang, he found that the tympanic membrane was normal under the electronic otoscope, and the electro-audiometry showed that the bone conduction threshold of the right ear was lower than the normal value of 25db (decibels). Eventually, Xiao Jiang was diagnosed with neural deafness.
Jiang Shuangxian, Chief Physician of the Department of Otolaryngology, Shangrao People's Hospital, Jiangxi Province: Long-term noise stimulation will cause damage to the inner and outer hair cells of the cochlea, and once the permanent hearing threshold shifts, it will cause permanent hearing damage.
According to medical staff, most hearing loss occurs slowly and gradually, so it is not easy to detect at an early stage. According to the World Health Organization, more than 1 billion young people between the ages of 12 and 35 are at risk of irreversible hearing loss. Personal audio devices are too loud and wearing headphones for long periods of time is a significant cause of risk.
Li Yongxin, Director of the Department of Otology of Beijing Tongren Hospital: We do not recommend wearing headphones frequently, especially if there is hearing loss in both ears, nor do we recommend long-term wear. Our headphones are very close to the ear, and if the volume is louder, it will damage the hair cells, and the hair cells are damaged, and once the damage is basically irreversible.
Medical staff suggest that you should always use headphones to master the three "60" principles, that is, the decibels of environmental noise floor should not exceed 60 decibels, the recommended volume of headphones should be less than 60% of it, and the time of using headphones should not exceed 60 minutes.
Persistent tinnitus or a precursor to hearing loss.
According to WHO's World Report on Hearing released in March 2021, one in five people worldwide suffer from hearing loss. Medical staff reminded that persistent tinnitus in middle-aged and elderly people is a precursor to hearing loss, and should be paid enough attention to early detection and medical treatment.
According to the medical staff, the first symptom of ear disease in most patients in clinical practice is sudden hearing loss, most of which are unilateral ear onset, and a few have bilateral occurrences at the same time or successively. Tinnitus is another important sign of sudden deafness, and it is not necessary to be overly nervous about transient tinnitus that occurs occasionally for a few minutes, but it is important to be wary of tinnitus that lasts more than a day or is accompanied by symptoms such as hearing loss.
Zhang Yi, Deputy Chief Physician of the Department of Neuro-Otology of Beijing Tongren Hospital: Usually our hearing loss may be common in two situations, one is that it occurs slowly in daily life, which is not easy for us to find, and the other is that the hearing loss occurs suddenly. Some patients will experience tinnitus and even vertigo. Some patients will have a feeling of ear stuffiness, be sure to go to the hospital in time, sudden deafness has a certain time limit, we recommend early detection as soon as possible, the sooner the better.
Newborn hearing screening is essential.
Hearing and language are important means for human beings to communicate with each other and understand the world, and hearing impairment will inevitably affect children's language development. Newborn hearing screening is essential as an effective measure for early detection of neonatal hearing impairment.
Newborn hearing screening refers to the objective, non-invasive, and rapid screening of newborns' hearing through professional detection methods such as otoacoustic emission after birth, in a natural sleep or quiet state.
Huang Lihui, researcher at Beijing Institute of Otolaryngology: Newborns can be preliminarily screened about two days after birth, which is called otoacoustic emission screening. If the child fails to pass the initial screening, it will take about 42 days to go to the designated re-screening unit for screening. If you do not pass the screening, you will be referred to one of our designated Childhood Hearing Impairment Centers for further hearing diagnosis and medical evaluation within three months.
In addition, experts suggest that some children also have normal hearing in the neonatal period and hearing loss in the growing stage. If your child is slow to respond to or does not answer other people's calls, has poor speech development, and has poor communication and communication skills, it is important to seek medical attention in time.
The first case of cochlear implant replacement in our country.
The world of hearing-impaired friends is silent, which makes them face great inconvenience and challenges in life, work and study. Fortunately, with the continuous advancement of technology, modern technology is creating new opportunities for people with hearing impairments and helping them open the door to the world of hearing.
Recently, Lu Feng, the first cochlear implant in China, underwent a second cochlear implantation in the First Affiliated Hospital of Gannan Medical University.
Lu Feng, the first cochlear implant in China: My new cochlear implant is directly connected with my mobile phone Bluetooth, and I can communicate very well with others in a noisy environment or other environments.
Lu Feng, a 59-year-old hearing-impaired patient, was deaf in both ears due to an accident at the age of 10, and in 1995, ** successfully performed cochlear implant surgery for him. When Lu Feng was implanted with a cochlear implant for the first time, he needed to make a 19-centimeter infusion in his head and insert the implant. Today, with the advancement of technology, cochlear implant surgery is mature and minimally invasive. Cochlear implants are divided into two parts: an external speech processor and an implant, which works by converting sound into a certain encoded form of electrical signal, and then "wake" the implanter's auditory nerve through the implanted electrode system to restore or reconstruct auditory function.
Liang Wei, Deputy Director of China Hearing and Language Research Center: With the development of IT technology, artificial hearing equipment is constantly being upgraded. This is also the direction that our scientific researchers are working towards, not only to let the hearing-impaired hear clearly, but also to listen well. On the basis of listening to the good people, they can realize their potential and create greater contributions to the society.
