Olga Beklemishcheva: Today we will talk about ocheric implantation. This is an operation that allows people to hear, absolutely devoid of hearing. I don’t even know how to name this treatment method - new or old. The fact is that in the world, in particular, in the United States, cochlear implantation has been made for more than 30 years. In Russia, it appeared relatively recently. Two years ago, it was made in a very limited quantity-five to six pieces per year.
