A case of cricoarytenoid joint arthritis associated with rheumotoid arthritis was reported. A 59-year-old female with a long history (40 years) of rheumatoid arthritis involving all joints including the intervertebral joints was brought to the hospital because of a sudden onset of severe dyspnea during physical training in December, 1989. Emergency tracheostomy was performed. A fiberscopic examination revealed swelling of the bilateral false cords and aryepiglottic folds and fixation of the

A CT scan demonstrated deformed arytenoid cartilages. The CT and EMG findings led us to the diagnosis of a laryngeal involvement of long-standing rheumatoid arthritis. Arytenoidectomy was conducted on the left side and the swelling of the false cords and aryepiglottic folds subsided following surgery. The vocal cords, however, remained fixed. Histologic findings noted in the extirpated arytenoid cartilage were similar to those in other joints having rheumatoid arthritis. It should be emphasized that otolaryngologists should have more awareness of the laryngeal involvement of rheumatoid arthritis in their clinical practice.
