According to our survey of cochlear implants (CI) in Japan, the number of pediatric CI increases and the number of bilateral CI (BCI) also tends to increase. BCI has better results than First CI (FCI), e.g. speech discrimination and intelligibility were improved not only in the silence but also under the noise. Many research articles also report in improvements of directionality, and hearing ability on the second CI side, tinnitus improvement, and so on. Meanwhile, a number of researchers have become more aware of single-sided deafness (SSD) in recent years throughout the world. Some foreign governments, excluding Japan so far, allowed CI for SSD because of its. Here, our study reports the effect of BCI in children, such as binaural hearing and the regular school enrollment rate (82/100 = 82%).
Our study compares the mean speech discrimination score using various tests with the 2nd CI and BCI according to the time interval between FCI and 2nd CI. Thus we can determine the critical interval time period between FCI and 2nd CI statistically. Finally discussed how to proceed with patients, considering simultaneous or sequential CI and provides the information for the future of BCI and binaural hearing.
