To compare the Neural Response Telemetry (NRT) results of the cochlear implanted children who showed wave 5 and who could not, in preimplantation ABR.
24 children (11 boys, 13 girls) with bilateral profound sensorineural hearing loss participated in this study. Age of children ranged between 13 and 60 months (mean 30 months). All participated children were implanted with Cochlear® Nucleus brand devices. In preoperative ABR evaluation with click stimulus in 100 dBnHL intensity level, 9 children showed wave V and 15 children did not. We compared intraoperative NRT results of 1st, 6th, 11th, 16th and 22nd electrodes, those were selected from 22 electrodes, of the two groups.
There was no statistically significant difference between the children who showed wave V and who did not in preoperative ABR, when compared the intraoperative NRT results of 1st, 6th, 11th, 16th and 22nd electrodes (p>0,05).
intraoperative NRT was obtained in all the implanted children with bilateral profound sensorineural hearing loss, even if they received wave V or not in preoperative ABR. There was no difference between any of the parameters of the test results of the two groups. Normal NRT results can be achievable when there is no wave V in preoperative ABR.
比较人工耳蜗植入术前听性脑干反应（ABR）检查中出现波Ⅴ和未出现波Ⅴ的儿童的神经反应遥测（NRT）结果。
24例双侧极重度感音神经性听力损失儿童（11例男孩，13例女孩）参与本研究。儿童年龄在13至60个月之间（平均30个月）。所有参与儿童均植入了科利耳公司的Nucleus品牌设备。在100 dBnHL强度水平的短声刺激术前ABR评估中，9例儿童出现波Ⅴ，15例儿童未出现波Ⅴ。我们比较了两组从22个电极中选出的第1、6、11、16和22号电极的术中NRT结果。
比较第1、6、11、16和22号电极的术中NRT结果时，术前ABR出现波Ⅴ和未出现波Ⅴ的儿童之间无统计学显著差异（p>0.05）。
所有双侧极重度感音神经性听力损失的植入儿童均可获得术中NRT结果，即使他们在术前ABR中出现或未出现波Ⅴ。两组测试结果的任何参数之间均无差异。术前ABR未出现波Ⅴ时也可获得正常的NRT结果。
