Cochlear implants only help when the auditory nerve itself is intact.
Evidence
The last step in the process, before the higher brain takes over, is sending the data formed in inner hair cells through the spiral ganglia to larger nerve bundles and the brain. We shall go no further with this, having finished the vibratory history, so to speak, except to say that if this last system is compromised, the bionic ear of the next section will do little good for the hearing-impaired patient. — Eric J. Heller, Why You Hear What You Hear- An…, 1962
