Using an otoadmittance meter the function of the middle ear was compared in 38 patients with rheumatoid arthritis (RA) and 30 matched controls with non-articular rheumatism. Patients with pre-existing ear disease were excluded from the study. No subjects in either group showed hearing loss on pure tone audiometry, but otoadmittance abnormalities were recorded in 16 of the RA (42%) and in 2 of the control groups (7%). The pattern of abnormality was similar in each case and indicated an increased laxity of the conducting system. The reason for this unexpected finding is unknown. There were no significant differences between the RA patients with normal or abnormal recordings as regards clinical or laboratory features or treatment.
使用耳声导抗仪，对38例类风湿性关节炎（RA）患者和30例匹配的非关节性风湿病对照者的中耳功能进行了比较。患有既往耳部疾病的患者被排除在研究之外。两组中均无受试者在纯音听力测定中出现听力损失，但RA组中有16例（42%）出现耳声导抗异常，对照组中有2例（7%）出现异常。每种情况下的异常模式相似，表明传导系统的松弛度增加。这一意外发现的原因尚不清楚。在临床或实验室特征或治疗方面，记录正常或异常的RA患者之间没有显著差异。
