Background and Objectives This study analyzed short-term clinical outcome and safetyof Neuro OneⓇ (Oticon Medical) cochlear implantation on postlingually deafened Koreanadults. Subjects and Method A prospective study was performed on five postlingually deafenedKorean adults who underwent Neuro OneⓇ cochlear implantation between April and June,2016. All cases were successfully implanted via round window approach. Preoperative puretone audiometry and speech perception score [phonetically balanced (PB) words, bi-syllablewords, Korean version-central institute for the deaf (K-CID)], intraoperative evoked compoundaction potential (ECAP), postoperative audiometry, aided warble-tone thresholds and speechperception scores after 6 months were evaluated. Residual hearing group was defined as patientswith below 40 dB of average audiometric threshold in low frequency (250 and 500 Hz). Preservation of residual hearing and postoperative complication were also evaluated. Results The mean age of five patients (3 men, 2 women) was 37.6 years. All of the recipientswere unsatisfied about the conventional hearing aid. Two patients met the criteria for belongingto a residual hearing group. The audiometric threshold on the implanted side was 102.8dB, and the opposite side was 89.6 dB. The speech perception score with hearing aid resultedin the PB word score of 35.5%, bi-syllable word score of 50%, and the open set sentence testof 62.5% on the average. The mean operation time was 87 minutes. Three patients showednormal ECAP response throughout the entire electrode intraoperatively, but the other two patientscould not detect ECAP response intraoperatively. However, we could eventually identifyECAP responses in all cases postoperatively. All patients of residual hearing group could preservetheir residual hearing without deteriorating more than 10 dB on audiometry. At 6months after implantation, there was significant improvement of speech perception scores (PBword score was 54.1%; bi-syllable word score was 68.1% and K-CID was 86.2%). Conclusion Neuro OneⓇ cochlear implant system was able to preserve residual hearing withrelative short operation time. Short-term clinical outcome showed no significant differencewith other cochlear implant devices. However, intraoperative ECAP measurement was notconsistent. Further investigation was necessary.
