We have reported two cases of acute, life-threatening upper airway obstruction due to previously unrecognized rheumatoid arthritis of the cricoarytenoid joints with severe acute and chronic deformities of the larynx. Attempted endotracheal intubation with the rigid laryngoscope failed in each case, resulting in the need for emergency tracheostomy. We recommend the use of the fiberoptic bronchoscope for elective or emergency endotracheal intubations in patients with severe rheumatoid arthritis involving the cervical spine and the larynx.
