As the indications for cochlear implant have expanded to include younger patients and individuals with greater degrees of residual hearing, increasing emphasis has been placed on atraumatic surgery and the preservation of the cochlear structure. Here, a descriptive prospective randomized study was performed. It was shown that residual hearing preservation is possible 12 months postoperatively with an atraumatic perimodiolar flexible electrode array CI532® (Cochlear Ltd, Sydney, Australia). Residual hearing preservation, considered as < 15 dB, was obtained in 70% of the cases. Better clinical outcomes and performance could be obtained compared with the previous perimodiolar CI512®, but further research and a longer follow-up are necessary to verify the impact of outcomes.
随着人工耳蜗植入的适应证已扩大到包括更年轻的患者和残余听力程度更高的个体，人们越来越重视无创手术和耳蜗结构的保留。在此，进行了一项描述性前瞻性随机研究。结果表明，使用无创的环模周柔性电极阵列CI532®（澳大利亚悉尼科利耳有限公司），术后12个月有可能保留残余听力。70%的病例实现了残余听力保留（定义为<15 dB）。与之前的环模周CI512®相比，可以获得更好的临床结果和性能，但需要进一步研究和更长时间的随访来验证结果的影响。
