The cricoarytenoid (CA) joint involvement in rheumatoid arthritis (RA) is

not uncommon. 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.
