The benefits and drawbacks of getting cochlear implants for those with a hearing impairment

A cochlear implant completely by-passes the normal hearing mechanism and stimulates the auditory nerve directly by means of an internally implanted electrode assembly. The implant consists of an external portion that located behind the ear and an interior portion which is surgically implanted under the skin. An implant has a microphone, a speech processor, a transmitter and an electrode array.

History[ edit ] An infant with a cochlear implant. This original design distributed stimulation using a single channel. Two years later they went their separate ways due to personal and professional differences.

White implanted a six-channel electrode in a patient's cochlea at Stanford University. Instead, the devices pick up sound and digitize it, convert that digitized sound into electrical signals, and transmit those signals to electrodes embedded in the cochlea. The electrodes electrically stimulate the cochlear nervecausing it to send signals to the brain.

A systematic literature review published in found that studies comparing the two approaches were generally small, not randomized, and retrospective so were not useful for making generalizations; it is not known which approach is safer or more effective.

Risks of the procedures include mastoiditisotitis media acute or with effusionshifting of the implanted device requiring a second procedure, damage to the facial nervedamage to the chorda tympaniand wound infections.

To avoid the risk of bacterial meningitiswhich while low is about thirty times as high compared to people who don't undergo CI procedures, the FDA recommends vaccination prior to the procedure.

Device failure requiring reimplantation is estimated to occur in 2. Up to one-third of people experience disequilibrium, vertigo, or vestibular weakness lasting more than 1 week after the procedure; in people under 70 these symptoms generally resolve over weeks to months, but in people over 70 the problems tend to persist.

The data also showed that no conclusions could be drawn about changes in speech perception in quiet conditions and health-related quality-of-life. There was only one good study comparing implanting implants in both ears at the same time to implanting them sequentially; this study found that in the sequential approach, the second implantation made no change, or made things worse.

This review also found that, overall, the efficacy of cochlear implants is highly variable, and that it was not possible to accurately predict which children will and will not acquire spoken language successfully.

This review found the quality of evidence to be poor and the results variable: After eliminating multiple uses of the same subjects, the authors found that people with UHL had received a CI.

A device made by Nurotron China was also available in some parts of the world. Each manufacturer has adapted some of the successful innovations of the other companies to its own devices.

There is no consensus that any one of these implants is superior to the others. Users of all devices report a wide range of performance after implantation.

For some in the deaf community, cochlear implants are an affront to their culture, which, as they view it, is a minority threatened by the hearing majority. This is consistent with medicalisation and the standardisation of the "normal" body in the 19th century, when differences between normal and abnormal began to be debated.

However, it has also been argued that this does not necessarily have to be the case: Deaf culture critics argue that the cochlear implant and the subsequent therapy often become the focus of the child's identity at the expense of a possible future deaf identity and ease of communication in sign language, and claim that measuring the child's success only by their mastery of hearing and speech will lead to a poor self-image as "disabled" because the implants do not produce normal hearing rather than having the healthy self-concept of a proudly deaf person.Understanding Cochlear Implants.
