摘要
目的旨在探讨ASSR与ABR在极重度感音神经性耳聋幼儿及成人感音神经性耳聋患者测试中的临床应用价值。方法对36例(72耳)小于3岁极重度感音神经性耳聋幼儿分别行ASSR和ABR测试;对32例(64耳)成人感音神经性耳聋患者分别行ASSR和电测听测试。结果①极重度感音神经性耳聋幼儿ABR均未引出V波,而ASSR在0.5kHz、1kHz、2kHz、4kHz的引出率分别为66.67%、86.11%、88.89%、94.44%,ASSR在0.5kHz、1kHz、2kHz、4kHz的阈值均数、标准差分别为82.56±9.26dBHL、90.31±6.94dBHL、88.12±7.93dBHL、88.62±8.12dBHL。②对成人感音神经性耳聋患者0.5kHz、1kHz、2kHz、4kHzASSR测试阈值与电测听语频听阈(dBHL)进行配对两两比较的t检验,各组P值均大于0.05,无显著性差异。结论ASSR有助于极重度感音神经性耳聋幼儿残余听力的客观评估,尤以高频听阈为佳;ASSR与电测听在感音神经性耳聋诊断上有良好的一致性。
Objective To evaluate the significance of the application of ASSR and ABR to estimate hearing thresholds of infants and adults with profound sensorineural hearing loss. Methods The measurements of ASSR and ABR were obtained from 36 infants （72 ears） and 32 adults （64 ears）both with profound sensorineural hearing loss. Results No measurable responses of Wave V in ABR were from in all infants in the study, but acquired from the measurements of ASSR, the expression of Wave V were 66.67%, 86.11%, 88.89% and 94.44% at 0.5 kHz, 1 kHz, 2 kHz and 4 kHz respectively. The thresholds of ASSR at 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz were 82.56 ± 9.26 dB HL, 90.31± 6.94 dB H L, 88.12 ± 7.93 dB HL and 88.62 ± 8.12 dB HL,respectively. In the frequencies of 0.5 kHz, 1 kHz, 2 kHz and 4 kHz, no statistically significant findings were noted between the thresholds of ASSR and behavioral audiometry by t test in adults（P〉0.05）. Conclusion The ASSR was more appropriate to evaluate the residual hearing of infants with profound sensorineural hearing loss, specially in high frequencies. The findings of ASSR and audiometry were better corrected in identifying sensorineural hearing loss.
