Cochlear implantation has become a common method of rehabilitation in severe to profound deaf children and adults. However, factors such as electrode position and preservation of hearing structures are paramount for better results. Technological improvements have been made both situations possible with thinner electrode arrays that allow round window approach and perimodiolar positioning. The aim of this multicenter study is to verify whether a new and thinner perimodiolar array show differences in impedances in the intraoperative room that may suggest less trauma than the previous generation of perimodiolar arrays. The impedances of all electrodes of twelve consecutive surgeries of the new perimodiolar device were compared with the impedances of randomly selected twelve surgeries in recent years of the previous generation of perimodiolar device performed by the same surgeons. Mean values of impedances in the apical region (electrode 22 to 15) were 6.66 kohms and 11.46 kohms for the new and the previous device, respectively. In the medial region (electrode 14 to 8) were 7.37 kohms and 10.97 kohms for the new and the previous device, respectively; and for the basal electrodes (from 7 to 1) they were 8.06 kohms and 11.41 kohms, for the new and the previous device, respectively, with statistical significance for all electrodes. Discussion will be directed towards whether this findings may lead to postoperative benefits such as lower stimulation levels and longer battery life. [ABSTRACT FROM AUTHOR] |
