Effect of initial switch-on within 24 hours of cochlear implantation using slim modiolar electrodes

Abstract Reducing electrode impedance is an important factor in improving the functional benefits of cochlear implants (CIs). The immediate effect of early switch-on within 24 h of surgery on impedance among CI recipients with various types of electrodes has been reported previously; however, the im...
