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]
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]
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 procedure is also used experimentally to treat tinnitus and vertigo caused by vascular compression on the vestibulocochlear nerve. [2] As the goal of the Jannetta procedure is to relieve (vascular) pressure on the trigeminal nerve, it is a specific type of a nerve decompression surgery. [3]
Deaf Groom Gets Cochlear Implant Just in Time for Wedding
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.

The NAD asserts that the choice to implant is up to the individual (or the parents), yet strongly advocates a fully informed decision in all aspects of a cochlear implant. Much of the negative reaction to cochlear implants stems from the medical viewpoint that deafness is a condition that needs to be "cured," while the Deaf community instead ...
These symptoms are not symptoms of Ménière's disease per se, but rather are side effects resulting from failure of the organ of hearing and balance, and include nausea, vomiting, and sweating, which are typically symptoms of vertigo, and not of Ménière's. [1] This includes a sensation of being pushed sharply to the floor from behind. [5]
