BACKGROUND Past studies using event-related potentials (ERPs) elicited to single syllable stimuli in unilateral and bilateral cochlear implant users have suggested reorganization of the auditory cortex within the first 6-8 mo postimplantation (Sharma et al, 2002a, 2002b, 2006; Bauer et al, 2006). Better behavioral performance with bilateral implants is expected when bilateral cochlear implantat...

BACKGROUND Visual cross-modal re-organization is a neurophysiological process that occurs in deafness. The intact sensory modality of vision recruits cortical areas from the deprived sensory modality of audition. Such compensatory plasticity is documented in deaf adults and animals, and is related to deficits in speech perception performance in cochlear-implanted adults. However, it is unclear ...

OBJECTIVE To estimate a residual hearing preservation in cochlear implant patients in short-, and long-term observation. MATERIAL AND METHODS A group of 40 subjects with preserved residual hearing were included to this study. In all of them cochlear implant was provided due to a neurosensonal hearing loss. In all subjects hearing was tested using traditional audiological test battery. Cochlea...

OBJECTIVE To determine the degree of tinnitus suppression provided by currently available multichannel cochlear implants and to determine factors that can influence this process. STUDY DESIGN Prospective cohort. SETTING Tertiary-care referral center. PATIENTS Thirty-eight adult patients (18 years of age or older) with severe-to-profound hearing loss and tinnitus who met criteria for cochl...

BACKGROUND Cochlear implants (CI) for the rehabilitation of patients with profound or total bilateral sensorineural hypoacusis represent the initial use of electrical fields to provide audibility in cases where the use of sound amplifiers does not provide satisfactory results. AIMS To compare speech perception performance after cochlear implantation in children with connexin 26-associated dea...

The present study investigated the ability of normal-hearing listeners and cochlear implant users to recognize vocal emotions. Sentences were produced by 1 male and 1 female talker according to 5 target emotions: angry, anxious, happy, sad, and neutral. Overall amplitude differences between the stimuli were either preserved or normalized. In experiment 1, vocal emotion recognition was measured ...

With broadening candidacy criteria for cochlear implantation, a greater number of pediatric candidates have usable residual hearing in their nonimplanted ears. This population potentially stands to benefit from continued use of conventional amplification in their nonimplanted ears. The purposes of this investigation were to examine the speech and language development of pediatric cochlear impla...

Abstract Background There is a greater incidence of mental health problems among children with hearing impairment compared to controls. A high proportion experience delays in understanding, recognizing, and using emotional expression. are additional difficulties post-cochlear transplant patients that may increase the risk developing psychopathology, such as anxiety disorder. Results Forty mothe...

Abstract Purpose of Review This review will highlight recent outcome-based evidence guiding decision making for cochlear implantation in advanced otosclerosis, related complications, and technical surgical considerations otosclerosis the obstructed cochlea. Recent Findings Cochlear results consistent, excellent auditory outcomes with improvement both objective speech recognition scores subjecti...
