The electrical stimulation generated by the Cochlear Implant (CI) may improve the neural synchrony and hence contribute to the development of auditory skills in patients with Auditory Neuropathy / Auditory Dys-synchrony (AN/AD). Goal: The goal of the research was to evaluate the auditory performance and the characteristics of the electrically evoked compound action potential (ECAP) in a group of 18 cochlear implants recipients with AN/AD.The auditory perception was evaluated by sound field thresholds and speech perception tests. To evaluate ECAP's characteristics, the threshold and amplitude of neural response together with the amplitude growth and recovery functions were evaluated at 80Hz stimulation rate.The CI was seen as an efficient resource to develop auditory skills in 94% of the AN/AD patients considered by the research. The auditory perception benefits as well as the possibility to measure the ECAP showed that the electrical stimulation could compensate the neural dys-synchrony caused by the AN/AD. However, a unique clinical procedure cannot be proposed at this point. Therefore, a careful and complete evaluation of each AN/AD patient before recommending the Cochlear Implant is advised

Cochlear implants (CIs) represent one of the most important achievements of modern medicine as, for the first time in history, an electronic device is able to restore a lost sense - hearin...
Investigation of a new ECoChG system (Electrocochleography) during the surgical insertion of cochlear implants, for patients with Advanced Bionics devices. The sound recordings created ma...
The purpose is to test the balance of children with unilateral,bilateral cochlear implants and patients having unilateral implants before,bilateral implants after surgery,using the Bruinin...
Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. While remarkably successful, even in the best of performers restoration of hea...
Cochlear implant microphones are subject to aging and dirtying. The evolution may affect their efficiency. Several signal coding strategies are used in cochlear implants and their behaviou...
Many individuals with bilateral cochlear implants hear different pitches when listening with their left versus their right cochlear implant. This conflicting information could potentially increase the...
As the incidence of rhytidectomy and cochlear implantation increases, so does the likelihood that an individual patient will undergo both procedures over their lifetime. This is particularly relevant ...
This paper describes the background, organization and findings of a project undertaken in 2016-2017, to examine the benefits and challenges of the use of the Cochlear Mini Microphone (MM) by the famil...
Variability in speech perception outcomes with cochlear implants remains largely unexplained. Recently, electrocochleography, or measurements of cochlear potentials in response to sound, has been used...
It is recognised that CT can be used to determine the cochlear duct length (CDL) when selecting an electrode for cochlear implantation. It is the practice of our institution to routinely use MRI as th...
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.
The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the SPIRAL GANGLION and project to the cochlear nuclei (COCHLEAR NUCLEUS). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the VESTIBULAR NUCLEI.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
