Twenty-nine female patients with definite or classical rheumatoid arthritis (RA) and 30 controls were studied in order to assess the prevalence of laryngeal involvement in patients with RA and the occurrence of extrathoracic airway obstruction. Laryngeal involvement was assessed by physical examination including direct fiberoptic laryngoscopy, respiratory function tests and low-voltage radiography. Physical examination revealed laryngeal involvement in 17 RA patients (59%), extrathoracic airway obstruction was indicated by spirometry in 4 (14%) and radiography revealed pathological findings in 3 patients (10%). One or more signs of laryngeal involvement were found in 20 patients (69%). Symptoms of breathing difficulties were common (75%) among patients with laryngeal involvement. The erythrocyte sedimentation rate and class-specific rheumatoid factors were not correlated to laryngeal involvement.
为评估类风湿关节炎（RA）患者喉部受累的患病率及胸外气道梗阻的发生情况，对29例确诊或典型RA女性患者及30名对照者进行了研究。通过包括直接纤维喉镜检查、呼吸功能测试及低电压放射成像在内的体格检查来评估喉部受累情况。体格检查发现17例RA患者（59%）存在喉部受累，肺活量测定显示4例（14%）有胸外气道梗阻，放射成像显示3例患者（10%）有病理表现。20例患者（69%）发现有一项或多项喉部受累体征。喉部受累患者中呼吸困难症状很常见（75%）。红细胞沉降率及分类特异性类风湿因子与喉部受累无关。
