摘要
目的:通过探讨大龄儿童及青少年患者人工耳蜗植入术后高频区电极舒适阈变化规律及特点,为尽早找出此类患者的合理阈值提供参考。方法:选取手术时年龄为6-18岁的大龄儿童及青少年患者50例,进行心理物理测试。观察比较开机时、开机后1个月、3个月、6个月和1年时,高频区电极(1-10号电极)在单电极测试的舒适阈值和实际使用的舒适阈值的变化和特点。结果:1号电极、5号电极和10号电极在开机时单电极测试的舒适阈均值和开机后1年单电极测试的舒适阈均值进行比较,二者之间的差异均有显著性意义(P<0.01)。1号电极、5号电极和10号电极在开机时、开机后1个月,单电极舒适阈均值和实际使用的舒适阈均值进行比较,二者之间的差异均有显著性意义(P<0.05)。单电极测试舒适阈均值与实际使用舒适阈均值之间的差值,在开机时最大,随时间的增加逐渐减小。结论:舒适阈值随开机时间的增加呈增加趋势,单电极测试舒适阈均值与实际使用舒适阈均值之间的差值在开机后6个月和1年时接近。对大龄儿童及青少年患者高频区电极舒适阈的设置要合适,以便帮助其尽快渡过适应期。
Objective：To investigate the changes and characteristics of comfortable levels in high frequencies after cochlear implants for elder children and adolescent patients by the basic mapping data. Method：Fifty elder children and adolescent patients who received surgery at the age of 6—18 years participated in this study. Using psychophysical test observe the changes of comfortable levels in single electrode test and comfortable levels in using at the time of switch-on,and 1 month,3 months,6 months and 1 year after switch-on. Result：The average of comfortable levels in single electrode tests in using No.1,No.5 and No.10 electrodes when switch-on and 1 year after switch-on were significantly different（P0.01）. The average of comfortable levels in single electrode test and the average of comfortable levels in using No.1、No.5 and No.10 electrodes when switch-on and 1 month after switch-on were significantly different（P0.05）. The difference between comfortable levels by using single electrode test and comfortable levels in use was maximum at switch-on, the data reduced gradually with time after switch-on. Conclusion： The comfortable levels elevated along with the time after switch-on. The difference between comfortable levels by using single electrode test and comfortable levels in use were similar at the time of 6 months and 1 year after switch-on. It is important to set the right comfortable levels in high frequencies for elder children adolescent patients, it can help them to go through adaptive period.
