Abstract
ObjectivesTo explore the causes of cochlear implantation and reference function of old electrical stimulation electrode in cochlear reimplantation in children. MethodsThe causes, surgical methods and problems found during the operations of 24 cases of cochlear reimplantation in Henan Children's Hospital from June 2016 to April 2018 were analyzed. ResultsTwenty-three cases successfully completed the surgery of cochlear-reimplantation, and the remaining one case had approximately 1/3 of the anterior end of the residual cochlear electrode due to high resistance at the time of withdrawal of the electrodes. The causes of re-implantation were implant equipment failure (eleven cases), elevated impedance values of all electrodes after head trauma (two cases), and implant prolapse together with the electrode caused by a traffic accident (one case). ConclusionThe old stimulus electrode can provide an important reference to reduce the risk of operation and ensure the success of the reoperation.
