| Outline of Final Research Achievements |
We analyzed that the intraoperative condition of residual hearing in cochlear implantation and variation influenced by operative stress are estimated with auditory brainstem response or auditory steady-state response. At first, we consider stimulation device used in intraoperative condition. Although, the adequate product adhesive covering auricle and whole surgical site was not founded. Intraoperative sound pressure produced by patient’s biomonitor was configured in soft sound and estimated with sound level meter. It was enabled to construct the silent environment, under 55dB sound level, in operation room. These result reveal that it is difficult to conduct the research at a stage prior to main plan and we could not find out effectual measure in the survey period.
