Your audiologist at ENT Associates of Alabama will check the physical fit to make sure they are comfortable. They will then be programmed and adjusted based on your hearing loss and lifestyle needs.
Your audiologist will then discuss care and maintenance of your hearing aids. You will learn how to use them correctly and make adjustments for different hearing environments, insert and remove them, change the batteries and clean and care for them properly. You will also learn tips and strategies for better communication.
Types of Implantable Hearing Devices
Cochlear implants are devices that are implanted surgically behind the ear. They contain an external portion consisting of a microphone, sound processor and transmitter, and an internal portion that includes a receiver and a group of electrodes.
How Does a Cochlear Implant Work?
The microphone picks up sounds in the environment, which are then converted by the sound processor into electronic signals that are sent to the transmitter. The transmitter forwards these signals to the receiver, where they are then passed on to the electrodes. The electrodes stimulate the auditory nerve, which carries the information directly to the brain, where it is interpreted as sound.
Cochlear implants allow those who are profoundly deaf to understand speech and other sounds.
Bone Anchored Hearing Devices
Bone anchored hearing devices consist of a titanium implant, an external abutment and a sound processor. Like cochlear implants, this system bypasses damaged hair cells in the auditory canal and middle ear, transmitting sound vibrations through the external abutment to the titanium implant, which naturally integrates (“ossifies”) with the skull bone over time.
Implantable hearing devices
Hearing aids are a benefit to millions of Americans with hearing loss. But as well as they perform, they do have their limitations.
How Does a Bone Anchored Hearing Device Work?
The bones of the skull act as conductors, transmitting these sound vibrations to the inner ear, where the nerve fibers responsible for hearing are stimulated. A bone anchored hearing device is especially useful for patients with conductive hearing loss and single-sided deafness.
Auditory Brainstem Implants
Auditory brainstem implants (ABI) are similar in concept to cochlear implants, but rely on electrodes placed directly on the brainstem that relay electronic signals to the brain. ABIs are less common, usually reserved for individuals whose auditory nerve does not function properly due to disease or trauma.
The majority of cases are related to a rare type of tumor known as neurofibromatosis type II (NF2). These patients have sensorineural hearing loss and, because the auditory nerve is damaged, do not benefit from cochlear implants.
Implantable hearing devices are surgically implanted instruments designed to improve the transmission of sound vibrations. There are several different types of implantable hearing devices; these include cochlear implants, bone anchored hearing aids and auditory brainstem implants.
