Congenitally deaf Japanese children with cochlear implants were tested on their recognition of theme songs from television programs that they watched regularly. The children, who were 4-9 years of age, attempted to identify each song from a closed set of alternatives. Their song identification ability was examined in the context of the original commercial(More)
OBJECTIVES To examine the ability of congenitally deaf children to recognize music from incidental exposure and the relations among age at implantation, music listening, and word recognition. DESIGN Seventeen child implant users who were 4 to 8 yr of age were tested on their recognition and liking of musical excerpts from their favorite television(More)
Japanese 5- to 13-yr-olds who used cochlear implants (CIs) and a comparison group of normally hearing (NH) Japanese children were tested on their perception and production of speech prosody. For the perception task, they were required to judge whether semantically neutral utterances that were normalized for amplitude were spoken in a happy, sad, or angry(More)
CONCLUSIONS Our results indicated that electric acoustic stimulation (EAS) is beneficial for Japanese-speaking patients, including those with less residual hearing at lower frequencies. Comparable outcomes for the patients with less residual hearing indicated that current audiological criteria for EAS could be expanded. Successful hearing preservation(More)
OBJECTIVES We evaluated the cortical activity of 2 successful prelingually deafened adult cochlear implant (CI) users who have been trained by auditory-verbal/oral communication since childhood. METHODS Changes in regional cerebral blood flow were measured by positron emission tomography using '8F-fluorodeoxyglucose while the subjects were receiving(More)
OBJECTIVE To assess the impact of cochlear implantation (CI) on children with cytomegalovirus (CMV)-induced deafness. STUDY DESIGN Retrospective chart review. PATIENTS Four children with congenital CMV-related deafness (CMV group) and 17 children with congenital deafness without CMV infection as the cause of deafness (non-CMV group). The age at CI(More)
Auditory neuropathy spectrum disorder (ANSD) is a unique form of hearing loss that involves absence or severe abnormality of auditory brainstem response (ABR), but also the presence of otoacoustic emissions (OAEs). However, with age, the OAEs disappear, making it difficult to distinguish this condition from other nonsyndromic hearing loss. Therefore, the(More)
OBJECTIVES We conducted multi-directional language development tests as a part of the Research on Sensory and Communicative Disorders (RSVD) in Japan. This report discusses findings as well as factors that led to better results in children with severe-profound hearing loss. METHODS We evaluated multiple language development tests in 33 Japanese children(More)
OBJECTIVES It is not unusual for a cochlear implantation (CI) candidate to have some type of ear malformation, in particular an abnormal course of the facial nerve (FN). In this study, we attempted to reconstruct a three-dimensional (3D) image of temporal bone structures with malformation using computed tomography (CT) imaging and examined its usefulness in(More)
CONCLUSIONS The present study yielded useful information concerning pre-lingually deaf adolescents and adults who try or manage to understand languages. PET-CT can provide insights into brain plasticity and elucidate which mode of communication is the most effective for education of such patients. OBJECTIVES To study the cortical activity in pre-lingually(More)
