A 63-year-old female with severe rheumatoid arthritis and respiratory obstruction with stridor due to cricoarytenoid (c.a.) arthritis is described. Low voltage radiography of the neck revealed erosive changes in the c.a. joints. At laryngoscopy the arytenoids were fixed in adduction, and there were signs of active arthritis. Corticosteroid therapy was instituted with remarkable effect on the obstruction. After the active arthritis had subsided, there remained limited arytenoid mobility with a glottic chink of about 5 mm, but no laryngeal symptoms.
本文描述了一名63岁女性，患有严重类风湿性关节炎，因环杓关节炎导致呼吸梗阻并伴有喘鸣。颈部低电压X线摄影显示环杓关节有侵蚀性改变。喉镜检查时，杓状软骨固定于内收位，并有活动性关节炎的体征。给予皮质类固醇治疗后，梗阻症状有显著改善。活动性关节炎消退后，杓状软骨活动仍然受限，声门裂约5毫米，但无喉部症状。
