Intracochlear electrode insertion of cochlear implant: a scoping review

Cochlear implant currently shows remarkable speech understanding performance despite use of non-optimized coding strategies for transmission of tonal information. Certain features of cochlear implant electrode arrays enable the preservation of intracochlear structures when the devices are inserted into the scala tympani. The standard location for insertion of electrode of cochlear implant is into the scala tympani. The failure of insertion of the electrode into scala tympani has been seen in clinical practice. Minimal or no insertion trauma, deep insertion to the apex of the scala tympani is possible using recently developed flexible long straight electrodes. Misplacement of cochlear implant electrode array is considered as a major complication during cochlear implantation. If there is any malformed cochlea, it needs to be diagnosed, and the right electrodes should be selected for each individual cochlea. The aim of this review article is to discuss on the current knowledge about the intracochlear electrode insertion of cochlear implant.
