目的研究听觉稳态诱发反应(ASSR)和听性脑干反应(ABR)阈与纯音听阈的差别和相关性。方法选择感音神经性聋患者(110耳)分别进行ASSR、ABR和电测听检查,比较ASSR、ABR反应阈及纯音听阈,同时就ASSR、ABR反应阈与纯音听阈进行相关性分析。结果ASSR和ABR反应阈与纯音听阈均有良好的相关性,ABR的反应阈与纯音听阈阈值接近,而ASSR反应阈与纯音听阈间差值较大。ASSR反应阈与纯音听阈间的相关性优于ABR反应阈与纯音听阈间的相关性。结论ASSR和ABR为较好的评估行为听阈的客观测听方法。
Objective To study the difference and correlation between auditory brainstem response (ASSR) and pure tone auditory threshold (ABR) thresholds. Methods ASSR, ABR and electrical audiometry were performed in patients with sensorineural hearing loss (110 ears). ASSR, ABR threshold and pure tone threshold were compared. The correlation between ASSR, ABR threshold and pure tone threshold was also analyzed. Results The ASSR and ABR thresholds correlated well with pure tone threshold. The response threshold of ABR was close to that of pure tone threshold, while the difference between ASSR threshold and pure tone threshold was large. The correlation between the ASSR threshold and the pure tone threshold was better than that between the ABR threshold and pure tone threshold. Conclusion ASSR and ABR are good objective measures of hearing threshold of assessment behavior.
