In this study, clinical assessment, laryngeal endoscopy, and high-resolution computed tomography (HRCT) were used in 15 patients with RA to evaluate the diagnostic criteria of CA joint involvement. Symptoms owing to CA joint involvement were present in 66.6% of the patients. The frequency of involvement was 13.3% on laryngeal endoscopy but 80.0% with HRCT assessment. The most common HRCT findings were CA prominence (46.6%), density and volume changes (46.6%), and CA subluxation (39.9%). In some of the patients, soft tissue swelling (20%) near the CA joint and narrowing in the piriform sinus (33.3%) were also observed. Radiologic abnormalities related to CA joint involvement generally precede clinical symptomatology. Therefore, HRCT evaluation may be a useful method in the assessment of CA joint involvement in RA patients to exclude possible causes of laryngeal signs and symptoms.eninfo:eu-repo/semantics/closedAccesscricoarytenoid jointhigh-resolution computed tomographyrheumatoid arthritisArticle32637337810.2310/7070.2003.139102-s2.0-154231893714967082N/AWOS:000189022600004Q4
