儿童患者植入诺尔康-晨星人工耳蜗术后听觉康复效果分析

The Hearing Rehabilitation Results of Deaf Children with Nurotron Venus Cochlear Implantation

目的：观察及分析听障儿童植入国产诺尔康－晨星人工耳蜗术后的听觉康复效果及人工耳蜗产品性能。方法选择2011年4月～6月植入诺尔康-晨星人工耳蜗系统的听障儿童60例，在开机后3个月、6个月、9个月、12个月进行听觉康复效果评估，同时对人工耳蜗产品的使用情况和工作状态随访。使用SPSS统计软件进行数据分析。结果60例患儿的人工耳蜗植入手术成功，产品的生物相容性和整体工作状态良好，受试者术后1个月开机后均能坚持每日配戴人工耳蜗，无与人工耳蜗植入相关的并发症。受试者声场言语频率的助听听阈测试，韵母、声母、单音节和双音节识别测试，林氏六音测试，IT-MAIS问卷评估结果较术前均显著提高。随着人工耳蜗使用时间的延长，受试者听觉能力逐渐提高。结论诺尔康－晨星人工耳蜗系统安全可靠，在恢复听觉、提高言语和声音感知与识别能力等方面效果良好。植入体纤薄，适合儿童植入。远期效果有待进一步观察。

Objective The aim of this study is to observe and analyze the auditory and speech rehabilitation outcomes as well as the performance of Nurotron Venus cochlear implant （CI） made in China among deaf children.Methods From April to June 2011, 60 deaf children received Nurotron Venus cochlear implantations. All CI systems of subjects were switched on 3 to 4 weeks after surgery, and the auditory rehabilitation outcomes were assessed 3 months, 6 months, 9 months and 12 months after being switched on. The effectiveness of Nurotron Venus CI system was evaluated using SPSS statistical software. Meanwhile, the safety and performance of Nurotron Venus CI system were followed-up. All pediatric recipients in this study have severe to profound hearing loss, aged from 12 to 71 months with an average age of 39.6 ＆#177;18.9 months. Results 60 deaf children were implanted with the Nurotron cochlear implants successfully. All the Nurotron recipients regularly used their devices which worked effectively. No complication or side effects related to implantation was found. The postoperative results of the aided hearing threshold test, consonants, vowels, monosyllable, disyllable, Ling Six Sound and IT-MAIS test improved significantly compared with the preoperative results. After a period of use, the auditory ability of those pediatric recipients progressed considerably.Conclusion The Nurotron Venus CI system made in China worked safely and effectively. The slim design of implant is suitable for pediatric implantation. However, further observation is still needed.
