Arytenoid subluxation (AS), ie, malpositioning of the arytenoid cartilage with abnormal but existent contact between the joint surfaces, is an uncommon entity, and fewer than 70 cases have been reported, 26 of which were in a recently published series. Usually, AS is the result of upper airway instrumentation, and only a few cases were reported to occur with external trauma to the neck. Some predisposing factors and possible mechanisms have been suggested, but the reason for ils occurrence remains obscure. Hoarseness and, to a lesser degree, dysphagia, odynophagia, cough, and sore throat may be indicative of AS. Diagnosis is established by the clinical course, laryngoscopy, and computed tomography. Electromyography and strobovideolaryngoscopy are additional diagnostic measures described. We report 7 cases of postintubation AS of long standing. Three of these patients had prior unilateral vocal cord paralysis, formerly undescribed as a possible contributing factor for AS. The pertinent literature is reviewed and treatment options are discussed.
