China News Service, Shanghai, March 3 (Reporter Chen Jing) March 3 is the 23rd National "Ear Day" and the 9th "World Ear Day".
The reporter learned on the 3rd that the "domestic artificial auditory brainstem implantation system" developed by the team of Professor Wu Hao, Dean of the Ninth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine, has completed the contract for the transformation of results.
This means that the localization process of the system is further accelerated.
According to reports, the localized brainstem implant device project led by Professor Wu Hao has entered the clinical trial stage.
Professor Wu Hao told reporters on the 3rd that congenital deafness is one of the most common birth defects, and 1/3 of the patients have severe hearing loss and require artificial hearing reconstruction.
The auditory brainstem implantation technology generates hearing by stimulating the higher-level neurons of the auditory pathway. However, because the implantation target is located at the cochlear nucleus of the brainstem, adjacent to many important blood vessels and nerves, the technology is extremely difficult and expensive. Only a few centres have the capacity to carry out this technology.
It is understood that in February 2019, the team led by his team implemented artificial auditory brainstem implantation for a child with congenital deafness, and successfully solved the problem of precise intraoperative cochlear nucleus positioning and effective brain-computer interface. So far, the team has completed more than 30 After the operation, all the children developed effective auditory and speech recognition ability, and the ability of language communication began to appear after 6-8 months.
The clinical results of the team have attracted great attention from experts in the international field, and have been invited to give special presentations at international conferences for many times.
"We expect that more children can restore their hearing through this, and at the same time expect the price of this advanced technology to further drop." Professor Wu Hao told reporters.
There are many factors that damage hearing, including genetics, drugs, noise, and degeneration of the auditory system.

It is reported that congenital microtia is also one of the major birth defects, manifesting as a deformity of the middle or outer ear.
If the patient's hearing is not effectively intervened in time, will it learn?
Work?
Negative impact on life and mental health?
During the interview, the reporter learned that dozens of hearing-impaired persons with microtia and financial difficulties have registered through the China Hearing Medicine Development Foundation and wore the dental bone conduction hearing aids donated by the public welfare.
They are the beneficiaries of the China Hearing Medicine Development Foundation Shengtuo Medical Hearing Aid Fund's public welfare action.
"
The dental bone conduction hearing aid is a non-surgical treatment method to achieve direct bone conduction. It transmits the sound to the cochlea non-destructively through the teeth that are closely connected to the skull without the attenuation of skin and soft tissue in the middle. High-frequency signals critical for speech recognition in noisy environments.
This allows patients not only to hear sounds, but also to hear the content of speech clearly, providing a new option for patients with severe conductive hearing loss and unilateral hearing loss.
Professor Gong Shusheng, chairman of the China Hearing Medicine Development Foundation and a well-known ENT expert in China, said: "The China Hearing Medicine Development Foundation Shengtuo Medical Hearing Aid Fund aims to provide charitable assistance so that the impoverished hearing-impaired people can have the opportunity to benefit from the latest technology. Hearing aid technology brings them new hope in life.
Mr. Liu was diagnosed with severe bilateral microtia and atresia of both ear canals from birth, which is a severe hearing impairment.
After many surgeries, the family was in debt.
Before that, Mr. Liu had some knowledge about bone conduction hearing aids.
About to enter work Mr. Liu hopes to try wearing bone conduction hearing aids.
He said that the news of the donation of bone conduction hearing aids seems to be a helping hand to "people who fall into the water".
"Now, there is no obstacle for my friends to communicate with me at a distance of ten meters. This is something that I never dared to think about before!"
"Although hearing impairment can be prevented and cured, prevention is more meaningful than treatment." Shi Haibo, director of the Department of Otolaryngology and Head and Neck Surgery at the Sixth People's Hospital affiliated to Shanghai Jiaotong University, told reporters on the 3rd.
According to reports, there are many factors that damage hearing, including genetics, drugs, noise, and degeneration of the auditory system.
Shi Haibo introduced that noise-induced deafness is characterized by binaural symmetry, progressiveness, and high-frequency hearing loss.
After a short-term exposure to strong noise, temporary hearing loss, tinnitus and other symptoms will appear, and it will return to normal after a few minutes from the noise environment.
If you are in a strong noise environment for a long time, the auditory organs of the inner ear will be irreversibly damaged, resulting in permanent hearing loss, which is "permanent threshold shift".
According to the expert, a large number of studies have shown that long-term exposure to high-intensity (>80 decibel) noise environments can not only cause damage to the auditory system, but also make people irritable, insomnia, memory loss, affect children's cognitive function, increase Risk of cardiovascular diseases such as hypertension and coronary heart disease.
On the same day, in the Shanghai Health Lecture Hall "Caring for Hearing Health, Listening to a Wonderful Future" special event hosted by the Shanghai Municipal Health Commission, the Office of the Shanghai Health Promotion Committee and the Shanghai Health Promotion Center, Shi Haibo told reporters that the human ear It is a very delicate and fragile organ, and good hearing is essential for maintaining quality of life.
People should pay attention to the protection of hearing in daily life and improve the awareness of noise protection.
He pointed out: "When people use headphones, they must control the volume and duration; when taking subways, planes and other means of transportation, they should try to use earplugs or noise-cancelling headphones; workers in noisy environments must wear protective tools in accordance with professional norms. He advised the public to control tobacco and alcohol, avoid staying up late, and receive regular ear and audiology examinations.
