对23例类风湿性关节炎患者和13例正常人的双耳进行听力学和电声导抗测试。听力学检查发现14例类风湿关节炎患者伴有传导性听力损失(3例)或感觉神经性听力损失(11例)，而对照组只有2例听力损失，均为感觉神经性听力损失。导纳数据显示59%的类风湿性关节炎患者有异常发现，而对照组只有4%。类风湿性关节炎样本中感音神经性听力损失的发生率增加并不能很容易地解释。在类风湿性关节炎患者中观察到的异常导纳发现的流行率表明，要么中耳僵硬增加，要么与韧带支抗稳定性降低相关。
Audiologic and electroacoustic immittance measurements were obtained from each ear of 23 patients with rheumatoid arthritis and 13 normal control subjects. Audiologic findings revealed 14 patients with rheumatoid arthritis with hearing loss of either conductive (three patients) or sensorineural (11 patients) type, while only two control subjects demonstrated hearing loss, both of sensorineural type. Immittance data revealed abnormal findings in 59% of the patients with rheumatoid arthritis as compared to only 4% of the control subjects. The increased incidence of sensorineural hearing loss in the sample with rheumatoid arthritis could not be readily explained. The observed prevalence of abnormal immittance findings in patients with rheumatoid arthritis suggested either increased middle ear stiffness or increased stiffness associated with decreased stability of ligamentous anchorage.
