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)
Mutations in WFS1 are reported to be responsible for two conditions with distinct phenotypes; DFNA6/14/38 and autosomal recessive Wolfram syndrome. They differ in their associated symptoms and inheritance mode, and although their most common clinical symptom is hearing loss, it is of different types. While DNFA6/14/38 is characterized by low frequency(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)
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)
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)
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)
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)
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)
CONCLUSIONS The present study confirmed the clinical characteristics of patients with SLC26A4 mutations: congenital, fluctuating, and progressive hearing loss usually associated with vertigo and/or goiter during long-term follow-up. This clarification should help to facilitate appropriate genetic counseling and proper medical management for patients with(More)
OBJECTIVE To evaluate the validity of cochlear implantation (CI) on prelingually deafened adults who have been trained by auditory-verbal/oral communication since childhood. METHODS Preoperative and postoperative data was investigated regarding the rehabilitation, hearing level, and educational experience of eight prelingually deafened adults. All eight(More)
