背景:迄今为止没有研究比较持续性和间歇性耳鸣患者的听力学特征。本研究根据耳鸣持续时间将耳鸣患者分为连续和间歇组,并比较了他们的听力学特征。
方法:本研究纳入了从2019年1月至2022年12月的604例耳鸣患者。临床表现,PTA结果,耳鸣的频率和响度,ABR,DPOAE,比较了持续性和间歇性耳鸣患者的TEOAE测试。
结果:在604名患者中,231例(38.2%)持续耳鸣,373例(61.8%)间歇性耳鸣。在耳科症状方面没有显著的组间差异,拟声词耳鸣.PTA显示听力阈值,除了在125赫兹,在连续而非间歇性耳鸣患者中明显更高。连续耳鸣患者的耳鸣响度明显高于间歇性耳鸣患者。ABR测试表明,连续的V波绝对潜伏期明显长于间歇性耳鸣。在所有测试频率(1、1.5、2、3和4kHz)下,连续而不是间歇性耳鸣的患者在TEOAE测试中的信噪比均显着降低。所有频率对声音刺激的反应率,除了1kHz,在DPOAE测试中,持续而不是间歇性耳鸣患者的DPOAE测试显着降低。
结论:持续性耳鸣在男性中更为常见,随着时间的推移更加持久,并且与较高的听力损失率有关。相比之下,间歇性耳鸣在女性中更为常见,敏锐地出现,并且与相对较低的听力损失率有关。根据本论文的研究结果,持续性和间歇性耳鸣患者的听力学特征似乎不同。
BACKGROUND: No studies to date have compared audiologic characteristics in patients with continuous and intermittent tinnitus. The present study classified tinnitus patients into continuous and intermittent groups based on tinnitus duration and compared their audiologic characteristics.
METHODS: This study enrolled 604 patients with tinnitus from January 2019 to December 2022. Clinical manifestations, PTA results, the frequency and loudness of tinnitus, ABR, DPOAE, and TEOAE tests were compared in patients with continuous and intermittent tinnitus.
RESULTS: Of the 604 patients, 231 (38.2%) had continuous and 373 (61.8%) had intermittent tinnitus. There were no significant between-group differences in otologic symptoms, tinnitus onomatopoeia. PTA showed that hearing thresholds, except at 125 Hz, were significantly higher in patients with continuous rather than intermittent tinnitus. The loudness of tinnitus was significantly greater in patients with continuous rather than intermittent tinnitus. ABR tests showed that the absolute latency of wave V was significantly longer in continuous than in intermittent tinnitus. Signal-to-noise ratios on TEOAE tests were significantly lower in patients with continuous rather than intermittent tinnitus at all frequencies tested (1, 1.5, 2, 3, and 4 kHz). Response rates to sound stimuli at all frequencies, except for 1 kHz, were significantly lower on DPOAE tests in patients with continuous rather than intermittent tinnitus.
CONCLUSIONS: Continuous tinnitus is more common in males, more persistent over time, and is associated with a higher rate of hearing loss. In contrast, intermittent tinnitus is more common in women, appears acutely, and is associated with a relatively lower rate of hearing loss. Based on the findings of the current paper, it seems that audiologic characteristics may differ between patients with continuous and intermittent tinnitus.
