Reference function of old electrical stimulation electrode in cochlear-reimplantation in children
1Department of Otorhinolaryngology, Children's Hospital Affiliated to Zhengzhou University, No 33, Eastern Outer-Loop of Dragon Lake, New district of Zhengdong, Zhengzhou 450018, China.
Objectives:
To explore the causes of cochlear implantation and reference function of old electrical stimulation electrode in cochlear reimplantation in children.
Methods:
The 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.
Results:
Twenty-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).
Conclusion:
The old stimulus electrode can provide an important reference to reduce the risk of operation and ensure the success of the reoperation.
