目的：本研究旨在检验以下假设：使用标准电极阵列和全长插入物可以保留儿科人群的残余听力。研究设计：回顾性回顾患者病历，设置：学术三级护理中心，患者：31例重度至重度听力受损的儿童患者，有部分残余听力预耳蜗植入术，干预：使用改良的“软手术”方案进行耳蜗植入术，主要结果测量：根据250、500和1,000 Hz的无辅助术前和术后听力图计算植入前和植入后的纯音阈值和纯音平均值。听力保留率被确定为完全（丧失听力）。
Objective: This study is designed to test the hypothesis that preservation of residual hearing in a pediatric population is possible using standard electrode arrays with full-length insertions. Surgical technique during implantation also is described.Study Design: Retrospective review of patient medical records.Setting: Academic tertiary care center.Patients: Thirty-one severely to profoundly hearing impaired pediatric patients with some residual hearing precochlear implantation.Intervention: Cochlear implantation using a modified "soft surgery" protocol.Main Outcome Measures: Preimplant and postimplant pure tone thresholds and pure-tone average were calculated from unaided preoperative and postoperative audiograms from 250, 500, and 1,000 Hz. Hearing preservation rates were determined to be complete (loss of
