The typical history of a patient with cricoarytenoid (CA) fixation is identical to that for patients with other forms of joint immobility. Depending on the position of the immobilized vocal fold and the unilateral or bilateral nature of the dysfunction, symptoms may range from mild dysphonia to frank aspiration and even acute airway compromise. The diagnosis is contingent on the exclusion of the many other causes of immobility, and appropriate confirmatory examinations and studies are necessary.
