Abstract

Purpose: This study aimed to investigate changes in auditory processing using auditory steady state responses (ASSR) in patients with idiopathic tinnitus.

Methods: 19 tinnitus patients (7 females) and 24 control subjects (9 females) without tinnitus were examined with multiple ASSRs. Three modulation frequencies of 20, 40, and 80 HZ were tested, and the steady state responses were compared between tinnitus and control group. Further, the thresholds in ipsi- and contralateral side to ear with tinnitus were compared.

Results: Our findings showed no significant difference in ASSR thresholds in ipsi- and contralateral side in tinnitus patients. However, we observed enhanced ASSRs at 40 and 80 Hz modulations in patients with idiopathic tinnitus compared to no-tinnitus control subjects.

Conclusion: The results of this study suggest possible sensory deficits along higher order auditory regions in patients with idiopathic tinnitus. Further, our data indicates a bilateral involvement of auditory pathway in these regions in patients with lateralized tinnitus.

特发性耳鸣患者的40和80 Hz听觉稳态反应增强。

目的：本研究旨在利用听觉稳态反应（ASSR）研究特发性耳鸣患者听觉加工的变化。方法：对19例耳鸣患者（女性7例）和24例无耳鸣的对照组（女性9例）进行多项assr检测。测试20、40、80 HZ三个调制频率，比较耳鸣组和对照组的稳态响应。进一步，比较耳鸣的单侧和对侧耳鸣阈值。结果：我们的研究结果显示耳鸣患者单侧和对侧的ASSR阈值无显著差异。然而，我们观察到特发性耳鸣患者与非耳鸣对照组相比，在40和80 Hz调制下的ASSRs增强。结论：本研究结果提示特发性耳鸣患者在高阶听觉区可能存在感觉缺陷。此外，我们的数据表明，侧耳耳鸣患者的这些区域的双侧听觉通路受累。

期刊介绍： JARO is a peer-reviewed journal that publishes research findings from disciplines related to otolaryngology and communications sciences, including hearing, balance, speech and voice. JARO welcomes submissions describing experimental research that investigates the mechanisms underlying problems of basic and/or clinical significance. Authors are encouraged to familiarize themselves with the kinds of papers carried by JARO by looking at past issues. Clinical case studies and pharmaceutical screens are not likely to be considered unless they reveal underlying mechanisms. Methods papers are not encouraged unless they include significant new findings as well. Reviews will be published at the discretion of the editorial board; consult the editor-in-chief before submitting.
