The MED-EL ABI stimulates the cochlear nucleus (CN) and provides users with a variety of hearing sensations to assist with sound awareness and communication. The ABI system is indicated for patients with non-functioning auditory nerves such as in Neurofibromatosis Type 2 and cochlear nerve aplasia. Auditory Brainstem Implant (ABI) ABI is a solution for individuals with hearing loss due to a non-functioning auditory nerve (Neurofibromatosis Type II).
Extensive rehabilitation is crucial for optimal benefit. In general speech understanding with an ABI is not equivalent to speech understanding with a cochlear implant. The Cochlear Implant was designed to direct sound to the Cochlea when an eardrum is ruptured, or a bone in the ear or other internal parts of the Middle Ear is broken. This is interpreted as a variety of hearing sensations which assist with environmental sound awareness and communication. ABI - Auditory Brainstem Implant When most people suffer from hearing loss, sound amplification is all that is needed to regain the missing sound. It bypasses non-functioning or absent parts of the inner ear and nerve and provides electrical stimulation directly to neural tissue of the cochlear nucleus (CN) in the brainstem.

The external audio processor is worn on the outside of the skin and contains a battery, one or two microphones and a fully digital signal processor.Īn ABI converts auditory signals into electrical signals. The silicone matrix is placed in contact with the neural tissue. The implantable component, also called the internal brainstem implant is the part that is surgically implanted into the brainstem and consists of a coil, a magnet that holds the audio processor in position over the implant, a demodulator, electrode array, ground electrode and a soft silicone matrix with 12 contact points. It consists of two major components namely an implant and an externally worn audio processor.
All implant users were between the ages of 414. The study included 33 parents of children with auditory brainstem implant, and 28 parents of children with cochlear implant were included as a control group. The auditory brainstem implant (ABI) system is a hearing solution for patients without a functional auditory nerve. This study aims to evaluate the everyday listening status of pediatric ABI users using the Turkish ABEL questionnaire.
