Abstract EN
The exchange of an cochlear implant or the re-positioning of an electrode have become more frequently required than a decade ago.
The consequences of such procedures at a microstructural level within the cochlea are not known.
It was the aim of the present study to further investigate the effects of an CI electrode pull-out.
Therefore 10 freshly harvested temporal bones (TB) were histologically evaluated after a cochlear implant electrode pull-out of a perimodiolar electrode.
In additional 9 TB the intrascalar movements of the CI electrode while being pulled-out were digitally analysed by video- capturing.
Histologically, a disruption of the modiolar wall or the spiral osseous lamina were not observed.
In one TB, a basilar membrane lifting up was found, but it could not be undoubtedly attributed to the pull-out of the electrode.
When analyzing the temporal sequence of the electrode movement during the pull-out, the electrode turned in one case so that the tip elevates the basilar membrane.
The pull- out of perimodiolarly placed CI electrodes does not damage the modiolar wall at a microstructural level and should be guided (e.g., forceps) to prevent a 90 o turning of the electrode tip into the direction of the basilar membrane.
