According to foreign media reports, Swedish scientists have recently invented a new medical implantable hearing aid, which can replace the middle ear to restore deaf people to normal hearing. Patients who have lost their hearing can use this new implanted hearing aid instead of the middle ear to regain normal hearing. Chalmers University of Technology in Sweden developed this unique device and successfully applied it to implant surgery. The hearing aid was implanted under the skull of a patient less than six centimeters behind the ear. The use of the skull to transmit sound waves to the inner ear, the so-called bone conduction, successfully enabled the patient to hear. Researchers said, "50% of the sounds people hear are transmitted by bone, so this sound sounds very natural." This new type of implanted hearing aid is called a bone conduction hearing aid. Unlike other hearing aids, this bone conduction hearing aid does not require a fixture, so there is no need to worry about losing some small parts, and it will not cause skin damage at the implantation site. infection. This technique is used to treat patients with long-term inflammation of the outer or middle ear, bone disease, or congenital dysfunction of the outer ear, resulting in hearing loss. For these patients, bone conduction hearing aids are very effective. In addition, this new implanted hearing aid can also help some patients with inner ear damage. The researchers hope to get the results of the first clinical trial early this year. For the future of this technology, they said: "We plan to extend this technology to treat ordinary patients within one to two years. We are in this technology During the development phase, a large investment is required to quickly apply the new technology. "
