背景听力困难（LiD）是指纯音测听正常的人在听和注意口语信息时存在的困难。内淋巴积水（Endolymphatic hydrops，EH）是一种常见的内耳疾病，与梅尼埃病有关，但也可能存在于无症状的耳中。ObjectivesUsing magnetic resonance imaging，we investigated EH in patients with LiD and assessed whether the severity of EH is related to the result of auditory processing tests（APTs）.通过APT和问卷进行评估。在获得知情同意后，20个同意的患者的内耳进行了评估，利用3特斯拉磁共振imaging.ResultsA高比例的患者诊断为LiD的APT有显着的高血压在耳蜗和前庭比以前报道的对照病例。噪声中言语测试的正确回答率显著低于无显著EH的患者。结论和意义在本研究中，耳蜗显著EH与听噪声能力差有关。EH的存在会影响听觉处理系统的功能，即使在标准听力测试中正常测试的耳朵中也是如此。
BackgroundListening difficulties (LiD) present difficulties in listening and paying attention to spoken information despite normal pure tone audiometry. Endolymphatic hydrops (EH) is a common inner ear condition associated with Ménière’s disease but may also be present in the asymptomatic ear.ObjectivesUsing magnetic resonance imaging, we investigated EH in patients with LiD and assessed whether the severity of EH was related to the results of auditory processing tests (APTs).Materials and Methods111 patients with no abnormalities on pure tone audiometry, but displaying difficulties in listening, underwent evaluation through APTs and questionnaires. Upon obtaining informed consent, the inner ears of 20 consenting patients were evaluated utilizing a 3-Tesla magnetic resonance imaging.ResultsA higher percentage of patients diagnosed with LiD by APTs had significant EH in the cochlea and vestibule than in previously reported control cases. The percentage of correct answers in the speech-in-noise test was significantly lower in patients with than in those without significant EH.Conclusion and significanceIn this study, significant EH of the cochlea was associated with poor listening to noise. The presence of EH affects the functioning of the auditory processing system, even in ears that test normally on standard audiometric tests.
