In the past two days, many people were anxious for the 26-year-old Zhangjiakou guy Li Ming because he accidentally lost the cochlear implant when he took the subway in Beijing. According to the "Emergency Search for Cochlear Implant" issued by his sister, it is wearing the Australian cochlear N6 sound processor, which is worth more than 200,000 yuan. If it is not found, it may be necessary to open another head for surgery.
What is the cochlear implant? Once lost, the implant needs to be re-craniotomy. Is this really the case?
The external machine loses the implant without replacement
"The cochlear implant is an electronic device that can repair part of the hearing of the hearing impaired. It is divided into two parts: the internal machine that is implanted into the inner ear by surgery, and the extracorporeal machine that is worn outside the ear." Otolaryngology, Beijing Tongren Hospital, Capital Medical University Li Yongxin, director of head and neck surgery - otology, said.
As for the loss of cochlear implant, it is not necessary to do craniotomy. Li Yongxin clearly said that it is not needed. Cochlear implant surgery usually involves a 3 cm incision behind the ear, which will not cause much trauma to the child. And Li Ming lost the extracorporeal machine, no need to re-operation, just need to re-purchase the extracorporeal machine and match it through the computer.
According to Li Yongxin, the ear is divided into three parts: the outer ear, the middle ear and the inner ear. The cochlea is an inner ear organ that converts external sounds from mechanical vibration signals into neurobioelectric signals. If the cochlea loses its function, the passage of sound to the hearing center of the human body will come to an abrupt end, and such a person becomes a monk. Unlike hearing aids, cochlear implants do not make the sound louder or clearer, but bypass the damaged part of the auditory system, directly stimulating the auditory nerve, so that deaf or severe hearing impaired patients receive sound. Many patients around the world have implanted cochlear implants, about half of which are children.
"The cochlear implant consists of an implant implanted in the human cochlea and a matching extracorporeal machine (sound processor). The implant is responsible for stimulating the auditory nerve, and the sound processor is responsible for collecting the sound and converting it into an electrical signal. In the case of the loss of the extracorporeal machine, the sound processor of the same brand can be re-matched with the original implant to re-visit the sound and no further surgery is required. Hu Xiaowei, assistant secretary-general of the Foundation, told the Science and Technology Daily reporter that the loss of extracorporeal machines only needs to be re-equipped. Foreign cochlear implants have been in existence for more than 30 years, and there have been no cases of replacement of internal organs.
"Without failure, the part that is implanted in the body can generally be worn for life," said Zhou Lijun, director of the China Hearing and Speech Rehabilitation Research Center.
In this regard, Yu Lisheng, director of the Department of Otorhinolaryngology, Peking University People's Hospital, also said that cochlear implant surgery does not require craniotomy. Cochlear implant surgery involves opening a small incision behind the ear, grinding a small groove in the skull, and then placing and securing the implant. “Experienced doctors can complete a cochlear implant in 30 to 40 minutes. In general, there should be no problem with the cochlear implant for 20 years after surgery.â€
As for the public concern, there will be a mismatch problem. Yu Lisheng said that there is no such problem, as long as the model is right.
"Craniotomy" "more than 200,000" is misleading to the public
"Throw away the foreign machine and buy one, you can get tens of thousands of dollars. Those who say that they want to spend 200,000 yuan are swearing." Yu Lisheng mentioned these very angry.
According to Hu Xiaowei introduction, there are currently three foreign enterprises and domestic enterprises get a cochlear Medical Device Registration Certificate can be used for children, with prices ranging from 80,000 to 300,000 yuan in, without surgery. "The donors choose foreign countries or domestic equipment, which is completely autonomous. Relatively speaking, choosing more foreign countries may feel better stability."
As for the price of Li Ming’s lost cochlear equipment, Hu Xiaowei said that it is impossible to judge. "The report said that the need for craniotomy, more than 200,000, etc. is misleading to the public, not at all prudent and rigorous, easily causing panic."
Why is the "cochlear loss" incident accompanied by the words "craniotomy" and "surgery costs more than 200,000"? There have been reports from the media that suspected of speculation. The reporter has repeatedly called Ms. Li to leave a phone call, but the other party did not answer.
"I don't know why I use the 'craniotomy' 'brain implant' 'hundreds of thousands'." Zhou Lijun said that he could not understand, maybe there are children who lost the cochlea, but should not speculate.
In this regard, some people working in the field of hearing impairment said: "Don't worry about the improper transfer of goodwill." He said that although the price is not as expensive as the net transmission, it is very painful for the average family to lose the cochlear. .
Before the deadline, the netizen Li Ming’s sister responded to the video and said: “If you want to confirm with me whether the information is true, please don’t call me first, because I am waiting for the clue. Regardless of whether we can find it on the 21st, we will give the public A reply."
