Successful cochlear implantation depends on many factors, one of which is the electrode type. The aim of this study was to evaluate it in terms of the preservation of residual hearing, as well as to investigate the effects of patient age and preoperative low-frequency hearing loss. METHODS: Twenty-three patients were implanted unilaterally with the HiFocus™ SlimJ electrode array. Pure tone audiometry (0.125-8 kHz) was performed preoperatively and at 1, 3, and 6 months postoperatively. Hearing preservation was established using the HEARRING group formula. RESULTS: Residual hearing was preserved in all patients. For hearing to be preserved, it was found that preoperative low-frequency hearing levels were more important than age. CONCLUSION: Residual hearing was preserved in all the patients who received the HiFocus™ SlimJ electrode array. Hearing preservation depended more on a patient's preoperative low-frequency hearing threshold than their age.
人工耳蜗植入成功取决于多种因素，其中之一是电极类型。本研究的目的是评估其在残余听力保留方面的情况，并研究患者年龄和术前低频听力损失的影响。方法：23例患者单侧植入HiFocus™ SlimJ电极阵列。术前以及术后1、3和6个月进行纯音听力测试（0.125 - 8 kHz）。使用HEARRING组公式确定听力保留情况。结果：所有患者的残余听力均得以保留。研究发现，为了保留听力，术前低频听力水平比年龄更为重要。结论：所有接受HiFocus™ SlimJ电极阵列植入的患者的残余听力均得以保留。听力保留更多地取决于患者术前的低频听力阈值而非年龄。
