Surgical procedures addressing arytenoid fixation can be organized into 2 categories. Techniques in the first group attempt to mobilize the cricoarytenoid (CA) joint in a manner analogous to joint mobilizations in the limbs. For example, in joint fixation resulting from traumatic fracture or dislocation of the cricoarytenoid (CA) joint, expedient relocation of the displaced arytenoid appears to be the procedure of choice, similar to the treatment choice for a dislocated knee or shoulder. Techniques in the second group are based on the concession that the joint is irreparably fixed; they focus on improving the airway by alternative means. This second category also applies to causes of glottic airway restriction other than joint ankylosis. [6]
