Reported rates of revision cochlear implant surgery vary in adults and children from 3.8% to 8% with the most common indications being device failure, infection, and migration of the implant or electrode. [46] Disequilibrium and vertigo after CI surgery can occur but the symptoms tend to be mild and short-lived. [47]
A cochlear implant is surgical implantation of a battery powered electronic medical device in the inner ear. Unlike hearing aids , which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain.
The internal implant sends the signals to the electrode array. The design of the electrode array is the key difference between a cochlear implant and an ABI. Whereas the electrode array for a CI is wire-shaped and is inserted into the cochlea, the electrode array of an ABI is paddle-shaped and is placed on the cochlear nucleus of the brainstem. [3]
The surgery involves a cochlear implant, a small electronic device, getting implanted into the cochlea, the spiral cavity of the inner ear, according to Johns Hopkins Medicine.

The symptoms of cochlear hydrops fluctuate, and the condition may stabilize or go away on its own after several years. However, because the organ of Corti undergoes stress during the hydrops episodes, long-term hearing loss, tinnitus, or hyperacusis is possible. It is considered by some that cochlear hydrops is an early form of Meniere's disease.
In most routine cochlear implant surgeries, any residual hearing will likely be destroyed. The residual hearing preservation rate in cochlear implantation is influenced surgical factors. The residual median hearing preservation for children was identified to be better when perimodiolar electrodes were inserted with AOS through fenestral ...
