title: Technical survey of the French role in multichannel cochlear implant development.
abstract: The objective of this review is to remind the ENT community of the essential role of the French teams in the development and finalization of the multi-electrode cochlear implant (MCI), which has deliberately been neglected, and to repair the oblivion into which France was curiously cast at the end of the last century. It aims to underline significant scientific publications from the researchers who played key roles in the development of MCIs. In conclusion, the Parisian team of the ENT Lab in Saint Antoine Hospital in Paris can claim priority for its work in five regards. We were the first: (1) to plot in 1976 a frequency map of the whole length of three living human cochleas; (2) on September 22, 1976, to set up total cochlear implantation in a deaf adult male with eight electrodes; (3) on March 16, 1977, to apply for a patent for an implantable hearing aid in humans; (4) to describe sound signal processing (SSP) for a functional cochlear implant able to supply totally deaf patients with speech discrimination without the help of lip-reading; (5) in 1983, to experimentally demonstrate why it was necessary to place a cochlear implant as early as possible, in case of profound neonatal deafness. An injustice has occurred. These facts will be brought to the knowledge of the scientific community.
