【摘要】：目的探讨1 000 Hz高频鼓室声导抗与畸变产物耳声发射(distortion product otoasoustic emission,DPOAE)结果的关系及1 000 Hz高频探测音声导抗在新生儿听力筛查中的意义。方法对50例(100耳)通过自动听性脑干反应(automatic auditory brainstem response,AABR)筛查的30~42天婴儿进行DPOAE及1 000 Hz高频探测音鼓室声导抗测试,对其结果进行分析。结果 150例婴儿100耳中通过DPOAE测试的为71耳,1 000 Hz鼓室导抗图正常(A型,D型)的为78耳。其中DPOAE测试通过的71耳中,1 000 Hz导抗图异常(B型,C型及其他型)为5耳,异常率7.04%;DPOAE未通过29耳中,1 000 Hz导抗图异常为17耳,异常率58.62%。DPOAE未通过者的高频鼓室声导抗异常率明显高于DPOAE通过者的声导抗异常率(58.62%,7.04%),两者存在显著性差异(P0.001)。2AABR通过的部分婴儿DPOAE及1 000 Hz声导抗检测结果仍存在一定异常(29%,22%)。结论 1 000 Hz高频探测音声导抗检测是婴儿听力筛查的重要辅助手段,其对听力损失的性质诊断及治疗具有重要意义。
[Abstract]:Objective to investigate the relationship between 1 000 Hz high frequency tympanic acoustic impedance and distortion product otoacoustic emission (DPOAE) results and the significance of 1 000 Hz high frequency detecting acoustic impedance in neonatal hearing screening. Methods DPOAE and 1 000 Hz acoustic conductance tests were performed in 50 infants (100 ears) who were screened by automatic auditory brainstem response automatic auditory brainstem responseAABR for 30 to 42 days, and the results were analyzed. Results among 100 ears of 150 infants, 78 ears of 71 ears with 1 000 Hz tympanogram were normal type A and D type by DPOAE test. Among the 71 ears tested by DPOAE, 5 ears were abnormal in type B, type C and other types of impedance mapping, and the abnormal rate was 7.04%. The abnormal rate of DPOAE was 17 ears without passing 1 000 Hz impedance map in 29 ears. The abnormal rate of high frequency tympanic acoustical impedance in patients without 58.62%.DPOAE was significantly higher than that in DPOAE patients (58.62%). There was significant difference between them. There were significant differences between the two groups. There were still some abnormal results in the detection of DPOAE and 1 000 Hz acoustic conductance in infants passed by P0.001. 2AABR. Conclusion 1 000 Hz high frequency detection of acoustic impedance is an important auxiliary method for hearing screening in infants. It is of great significance in the diagnosis and treatment of hearing loss.
