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 investigate the clinical value of ASSR and ABR in the testing of patients with severe sensorineural hearing loss and sensorineural hearing loss in adults. Methods ASSR and ABR tests were performed on 36 children (72 ears) under 3 years old with severe sensorineural hearing loss. ASSR and electric audiometry were performed on 32 cases (64 ears) of adult sensorineural hearing loss. Results ① The ABR of the children with severe sensorineural hearing loss did not induce V wave. The lead rates of ASSR at 0.5kHz, 1kHz, 2kHz and 4kHz were 66.67%, 86.11%, 88.89% and 94.44%, respectively. The ASSR at 0.5kHz, The threshold mean values of 1kHz, 2kHz and 4kHz were 82.56 ± 9.26dBHL, 90.31 ± 6.94dBHL, 88.12 ± 7.93dBHL and 88.62 ± 8.12dBHL, respectively. (2) Pairwise comparisons of pairwise comparisons of t-test of 0.5 kHz, 1 kHz, 2 kHz, 4 kHz ASSR and dBHL of adult sensorineural hearing loss showed that the P values in all groups were greater than 0.05 and no significant difference . Conclusion ASSR contributes to the objective assessment of residual hearing loss in children with very sensorineural hearing loss, especially in high-frequency hearing thresholds. ASSR and electrical audiometry have good agreement in the diagnosis of sensorineural hearing loss.
