目的 :对不同年龄使用人工耳蜗患者的心理物理测试进行分析和比较。方法 :共有 170例使用澳大利亚 2 4M型人工耳蜗系统的患者参加本次试验。将患者按年龄分为A(<3岁 )、B(3～ <6岁 )、C(6～ 12岁 )、D(>12岁 ) 4组。心理物理测试主要包括阈值和舒适阈的测试。结果 :开机后 1个月 ,A组与D组患者各电极 (除2 0号电极 )的舒适阈的差异均有统计学意义 (P <0 .0 1,其中 2、18、19、2 1、2 2号电极P <0 .0 5 )。开机时 ,D组患者实际使用舒适阈与舒适阈差值的标准化值的均值与A、B、C组患者的均值之间的差异均有统计学意义 (P <0 .0 1,其中与C组的差异P <0 .0 5 )。开机 1周时 ,D组患者实际使用舒适阈与舒适阈差值的标准化值的均值与A组的均值之间的差异有统计学意义 (P <0 .0 5 )。结论 :不同年龄患者的心理物理测试存在差异。患者使用人工耳蜗系统的早期 ,不同年龄患者实际使用舒适阈与舒适阈差值的标化值的差异有统计学意义。
OBJECTIVE: To analyze and compare the psychophysical tests of cochlear implant patients of different ages. METHODS: A total of 170 patients using the Australian 24 M artificial cochlear implant system participated in this study. The patients were divided into four groups according to their age: A (<3 years), B (3 ~ <6 years), C (6-12 years), and D (> 12 years). Psychophysics tests include thresholds and comfort threshold tests. Results: At the first month after starting up, there was significant difference in the comfort threshold between the electrodes of group A and group D (except 20 electrodes) (P <0.01, of which 2,18,19,21 , 2 2 electrode P <0. 05). At start-up, there was significant difference between the mean of standardized values of comfort threshold and comfort threshold of patients in group D and the mean of patients of groups A, B and C (P <0. 01, Group differences P <0. 05). At 1 week after starting-up, there was a significant difference between the mean of standardized values of comfort threshold and comfortable threshold actually used in group D and the mean of group A (P <0. 05). Conclusions: There are differences in psychophysical tests among patients of different ages. There was a statistically significant difference in the standardized values of comfort thresholds and comfort threshold differences between patients using the cochlear implant system and patients of different ages.
