2Binaural integration abilities in bilateral cochlear implant user显示文摘Bilateral Cochlear implants(CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests: the Japanese Hearing in Noise Test(HINT-J), the dichotic listening test(DLT), the Rapidly Alternating Speech Perception(RASP) test, and subjective auditory perceptual assessment. The HINTJ score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results.Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.Chie Obuchi Masae Shiroma Sayaka Ogane Kimitaka Kaga 2015Journal of Otology2015,10,4:2
