Background: There has been increasing demand for the cochlear implantation of children who demonstrate some auditory capacity with conventional hearing aids. The purpose of this study was to examine speech recognition outcomes in a group of children who were regarded as borderline candidates for cochlear implantation as their residual hearing and/or auditory functioning levels exceeded typical ...

Cochlear implants are first true bionic sense organs Like human inner ear hair cells they convert mechanical sound energy into electrical impulses. Cochlear implants are not hearing aids which merely amplify mechanical sound waves and increase their energy content Otter et al have shown that in the normal auditory nerve in young people there are approximately 35,000 nerve fibres; they concluded...

Cochlear implantation is considered to be a safe and effective treatment for severe to profound sensorineural hearing loss. Device failures are rare. We report the cases of 2 patients--a 44-year-old woman and a 3-year-old boy--with cochlear implants who were referred to our tertiary cochlear implant center for treatment of magnet migration secondary to mild head trauma. The migration had led to...

Users of cochlear implants (auditory aids, which stimulate the auditory nerve electrically at the inner ear) often suffer from poor speech understanding in noise. We evaluate a small (intermicrophone distance 7 mm) and computationally inexpensive adaptive noise reduction system suitable for behind-the-ear cochlear implant speech processors. The system is evaluated in simulated and real, anechoi...

HYPOTHESIS Processes of scattering and attenuation were investigated to determine the consequence on dose distributions by having a cochlear implant in the field of therapeutic radiation. BACKGROUND Radiation oncology medical accelerator beams of 6- and 18-MV x-ray energy were used. Five cochlear implants were investigated. METHODS Each implant model was individually studied using computer ...

The aim of this study was to analyse sibilant production of cochlear implant (CI) patients, comparing them with normal hearing speakers (NH). Because of the inhomogeneity of cochlear implant patients, in this study they were divided into four groups, depending on whether they are prelingually or postlingually deaf speakers and the period of time between the deafening and the implantation of a c...

Action theory and the qualitative action-project method are used in this study to address and illustrate the complexity of parenting children who have received cochlear implants (CIs) as well as the intentionality of parents engaged in that process. "Action" refers to individual and joint goal-directed and intentional behaviors. Action theory has the advantage of using the perspectives provided...

BACKGROUND The cochlear implant (CI) restores hearing to deafened individuals, allowing most CI users to reach an excellent level of speech discrimination, often to the point of being able to use a telephone. The increased ability to communicate afforded by cochlear implantation has been shown to have a significant positive effect on the quality of life of deafened individuals. Does CI lead to ...

OBJECTIVES To assess the effect of an intraoperative perilymph fluid gusher during cochlear implantation on speech perception abilities in pediatric patients with labyrinthine anomalies. SETTING Tertiary care academic referral center. METHODS Seventy subjects with labyrinthine malformations who received a cochlear implant were identified in our pediatric cochlear implant database. In 30 cas...
