The Cochlear Implant

What is a CI?

High-tech behind the ear – The Cochlear Implant (CI)
Cochlear implants are used in cases of severe inner ear hearing loss when the cochlea no longer
functions properly. In such cases, sound waves are no longer converted into nerve impulses. The cochlear implant takes over this task by directly stimulating the auditory nerve with electrical signals.
The system consists of two parts. In the external component, speech and environmental sounds are captured by a microphone and transmitted to the sound processor. The sound processor analyzes, filters, and encodes these sounds into electrical impulses.

These impulses are sent through the skin to the internal component, the implant, via a transmitting coil, similar to a radio signal.
A magnet in the coil holds it precisely in place over the implant. The implant is surgically placed behind the ear. It receives the converted signal and transforms it into electrical impulses once again. These impulses are delivered directly into the cochlea via an electrode array, where the endings of the auditory nerve are located.

The fastest progress is typically seen in individuals who became deaf suddenly due to sudden hearing loss.
Dieses Implantat wird in einer Operation hinter dem Ohr eingesetzt. Hier wird das umgewandelte Signal empfangen
und wiederum in elektrische Impulse umgewandelt. Diese Impulse werden von einem Elektrodenbündel direkt in die Hörschnecke geleitet,
wo sich die Enden der Hörnerven befinden.

“Electronic hearing” naturally differs from normal hearing. Individual outcomes with a cochlear implant vary significantly.
The fastest progress is typically seen in individuals who became deaf suddenly due to sudden hearing loss.
Since their auditory and speech centers are already developed, the brain can process the new auditory impressions relatively quickly.
About two-thirds of these patients are able to understand speech again without lip reading or even use the telephone.
Although sounds and words may initially seem different and music may not sound pleasant at first, targeted training can significantly improve musical perception over time.

Children born deaf achieve the best results when implantation takes place as early as possible, ideally between the first and second year of life.
During this period, brain structures develop optimally to process new auditory input.

The use of cochlear implants for people with hearing impairment began in the early 1980s.
Since then, more than 700,000 people worldwide have benefited from this technology.
If the implantation is performed later, it may take correspondingly longer for the positive results to become visible.

Types of Sound Processors

Cochlear implant (CI) sound processors are available in different types,
varying in functionality, wearing style, and additional features.
The most common types include:

Further information on cochlear implants can be found on the websites of the respective manufacturers.

• Cochlear: Cochlear™ Nucleus® System (cochlear.com)
• MED-EL: Cochlea-Implantate von MED-EL (medel.com)

The appropriate hearing system is usually selected and, if necessary, implanted by ear, nose, and throat (ENT) specialists and hearing aid acousticians in close collaboration with the patient. It is important to note that no single hearing system is equally suitable for all people with hearing loss. Therefore, the decision to opt for a cochlear implant also requires a comprehensive audiological evaluation and consultation with healthcare professionals.

The Cochlear Osia System

The Cochlear Osia System is an advanced implantable hearing solution designed for people with
conductive or mixed hearing loss. It combines the advantages of bone-anchored hearing systems
(BAHA, Bone Anchored Hearing Aid) with state-of-the-art technology to enhance
the overall hearing experience.

Here are some key features of the Cochlear Osia System:

1. Improved Hearing: The Osia System transmits sound through the bone directly to the inner ear,
   bypassing the outer and middle ear. This allows for clearer and more natural sound perception.
2. Implantable Technology: The Osia System is surgically implanted in the skull bone behind the ear.
   A small device, known as the implant, is placed under the skin, while the external sound processor is worn discreetly outside.
   This enables comfortable and subtle everyday use.
3. Connectivity: The Osia System can connect wirelessly to various audio devices such as smartphones,
   televisions, and other Bluetooth-enabled devices,
   ensuring seamless hearing in different listening environments.
4. Personalization The sound processor can be individually programmed to match the wearer’s
   specific hearing needs, providing optimized sound quality and a personalized listening experience.
5. Improved Quality of Life: By enhancing hearing ability in people
   with conductive or mixed hearing loss, the Osia System can significantly improve communication,
   participation, and overall quality of life.

Bone Conduction Implants

Bone conduction implants are implantable hearing systems designed
to help people with certain types of hearing loss.
They are a solution for people for whom conventional hearing aids are ineffective due to
conductive hearing loss or certain abnormalities of the outer or middle ear.

Here are the basic features and aspects of bone conduction implants:

1. Implantable Technology: The system consists of a small implant placed in
   the skull bone behind the ear or in the middle ear.
   This implant serves as an anchor point for the audio processor.
2. Bone-to-Bone Transmission: Instead of conducting sound vibrations through the oute
   and middle ear, the system transmits sound directly through the skull bone to the inner ear.
   This allows people with conductive hearing loss to hear sound more effectively.
3. External Audio Processor: The external audio processor is worn over
   the skin and connected to the implant in the skull bone. This processor picks up sound, converts it into vibrations,
   and transmits these vibrations to the implant,
   which then transmits them directly to the inner ear.
4. Treatment of Various Types of Hearing Loss: The system can be used for various types of hearing
   loss, including conductive, mixed,
   and unilateral hearing loss.
5. Customizable Settings: The audio processor can be customized to meet the wearer's
   specific hearing needs.
