Why Implantable Hearing Devices?

Implantable middle-ear hearing devices were developed to treat conductive and sensorineural hearing loss. These devices improved fidelity by directly stimulating the hearing bones, and they improve comfort by allowing the ear canal to remain open.

Why do we need implantable hearing devices?

Combined hearing loss is an essential indication for implantable hearing systems. ... Patients with mild sensorineural deafness usually benefit from transcutaneous bone conduction implants (BCI), while percutaneous BCI systems are recommended also for moderate hearing loss.

Why would a deaf person want a cochlear implant?

A deaf person does not have a functioning inner ear. A cochlear implant tries to replace the function of the inner ear by turning sound into electrical energy. This energy can then be used to stimulate the cochlear nerve (the nerve for hearing), sending "sound" signals to the brain.
