title: [The monochannel Monomac and multichannel Minimac cochlear implants].
abstract: Monomac monochannel and Minimac multichannel cochlear implants bring to the remaining hearing fibers sound information that is previously converted into adequate electric signals. Both function at constant currents. The Monomac monocanal system possesses only one electrode implanted either inside or outside the cochlea and sends off sound of basic laryngeal rythm to all the nervous fibers. The Minimac is entirely numerical and sends off the whole of the sound information by splitting it into 15 frequency tracks, to 15 electrodes inserted within the scala tympani by means of an electrode-holder. Programming allows for selecting specific values from each frequency track and thus regulating the needed compression individually. Both these implants (Monomac and Minimac) work no conflictlessly but complementarily to each other because they answer different, well-defined clinical needs.
