Inflammatory Conditions of the Larynx
Essential features. Reduction of motion in cricoarytenoid or cricothyroid joint, due to inflammation. Palpation of the arytenoid cartilage reveals decreased or no mobility of the cricoarytenoid joint. (Range of motion cannot be determined manually for the cricothyroid joint.) In more severe cases, the arytenoid cartilage or cartilages may become ankylosed.
