Background The authors' aim was to compare the influence of various electrode designs on selected objective and subjective clinical outcomes for cochlear implant recipients using the same model of receiver-stimulator, Cochlear™ Nucleus® Profile Series and sound processor.
Methods A multicenter study with subjects with profound sensorineural hearing loss, who were implanted and followed up in two tertiary centers. A total of 54 ears were implanted with Cochlear™ Nucleus® CI532, 51 with Cochlear™ Nucleus® CI522 and 54 with the Cochlear™ Nucleus® CI512. Implant loss and intraoperative electrophysiological tests (electrically evoked stapedial reflex threshold [ESRT], neural response telemetry threshold [T-NRT] and impedance), postoperative data (C-level, T-level, dynamic range, T-NRT and power consumption) and intracochlear position of the active electrode were analyzed with Nucleus Custom Sound 4.4 software.

The purpose of this study is to evaluate and document longitudinal efficacy in young children implanted bilaterally with MED-EL COMBI 40+ / PULSARCI100/SONATATI100 cochlear implant systems...
The primary objective of this study is to assess the usability of a Cochlear implant system.
The purpose of this study is to show that cochlear implant treatment improves the overall health related quality of life and general well-being in elderly individuals.
The purpose of this study is to understand the speech perception in noise and in quiet and localization benefits in a laboratory setting in listeners that receive a cochlear implant in an ...
Cochlear implants require programming on an individual basis to provide appropriate levels of electrical stimulation. This program, or "map", is placed in the speech processor of the cochl...
This study evaluated the influence of the performance of the first cochlear implant (CI-1) on the second implant (CI-2) and the significance of inter-implant intervals in children with sequential coch...
Our aim was to determine the effect of acute changes in cochlear place of stimulation on cochlear implant (CI) sound quality.
Previous research showed benefits of remote wireless technology in bilaterally moderate-to-severe hearing-impaired participants provided with hearing aid(s), cochlear implant(s) (CIs), or bimodal devi...
Cochlear implants are one of the most successful neuroprosthetic devices that have been developed to date. Profoundly deaf patients can achieve speech perception after complete loss of sensory input. ...
The data logs of Cochlear Nucleus cochlear implant (CI) sound processors show large interindividual variation in children's daily CI use and auditory environments. This study explored whether these di...
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.
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.
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.
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.
The sensory ganglion of the COCHLEAR NERVE. The cells of the spiral ganglion send fibers peripherally to the cochlear hair cells and centrally to the COCHLEAR NUCLEI of the BRAIN STEM.
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...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
