Abstract
What physicians and patients should know about different designs of cochlear implant electrodes?
Highlights
Cochlear implant (CI) has successfully restored hearing, improving the quality of life in adults and providing candidates with normal developmental and educational opportunities
Improvements in coding strategies [1,2,3,4] and advancements in speech processors [5] have resulted in an overall improvement in the performance of the CI, the electrode considered as an important element as it comes into direct contact with the intra-cochlear tissues that line the neural elements [6]
For a CI user to fully benefit from their device, the following factors need to be considered: (i) electrode array insertion depth and cochlear coverage [7], (ii) matching neuro-tonotopicity, (iii) atraumatic electrode array insertion and insertion forces against the intra-cochlear structures [8] and (iv) choosing an electrode array that matches the recipient's individual cochlear anatomy especially when the anatomy is malformed and a regular CI electrode will not give an optimal placement closer to the neural structures
