The purpose of this study is to compare the characteristics of psychophysical tests between cochlear implant children with large vestibular aqueduct syndrome and normal inner ear and to analyse the characteristics of psychophysical and impedance tests for cochlear implant patients with large vestibular aqueduct syndrome.
One hundred and thirty-one cochlear implant pre-lingual deafness patients participated in this study. They received cochlear implant surgery at the age of 1.5 to 12 years old from Nov, 1998 to Aug, 2003. The patients were divided into two groups. Group A had 111 patients with normal inner ear. Group B had 20 patients with radiographically proven large vestibular aqueduct syndrome. All of the patients were inserted with Nucleus 24M. The time of the first programming session was approximately 4 weeks after surgery. The psychophysical tests included T and C-Level tests. The programming techniques used in the test were suitable for the age of the patients. The R116 and R126 software were used to test the impedance of the electrodes automatically.
Using the independent-samples t-test, the impedance and T/C-Level of each electrode did not differ significantly between group A and B ( P > 0.05). The impedance and T/C-Level were not significantly different between group A and B at the time of switch-on, 1 week, 2 weeks, 3 weeks, 2 months, 3 months, 6 months, 9 months and 1 year after switch-on (P > 0.05).
The parameters of mapping were not significantly different between cochlear implant children with large vestibular aqueduct syndrome and normal inner ear. The management and procedure of mapping used in cochlear implant children with normal inner ear can be used in the children with large vestibular aqueduct syndrome.
本研究旨在比较大前庭导水管综合征的人工耳蜗植入儿童与内耳正常儿童的心理物理学测试特征，并分析大前庭导水管综合征人工耳蜗植入患者的心理物理学和阻抗测试特征。
131例人工耳蜗植入的语前聋患者参与了本研究。他们于1998年11月至2003年8月期间接受人工耳蜗植入手术，年龄在1.5至12岁之间。患者被分为两组。A组有111例内耳正常的患者。B组有20例经影像学证实为大前庭导水管综合征的患者。所有患者均植入了Nucleus 24M。首次编程时间约为术后4周。心理物理学测试包括T和C级测试。测试中使用的编程技术适合患者年龄。使用R116和R126软件自动测试电极的阻抗。
采用独立样本t检验，A组和B组各电极的阻抗和T/C级差异无统计学意义（P>0.05）。开机时、开机后1周、2周、3周、2个月、3个月、6个月、9个月和1年时，A组和B组的阻抗和T/C级差异无统计学意义（P>0.05）。
大前庭导水管综合征的人工耳蜗植入儿童与内耳正常儿童的图谱参数差异无统计学意义。内耳正常的人工耳蜗植入儿童所采用的图谱管理和程序可用于大前庭导水管综合征儿童。
