“…Close et al [6] described certain factors that may be involved in the appearance of this condition by weakening the cricoarytenoid joint capsule, these are: chronic use of corticosteroids, laryngomalacia and acromegaly. The dislocation of the arytenoid cartilage has been classified in the literature as anterior and posterior [3]. The anterior dislocation is characterized by an anteromedial and inferior displacement of body of the arytenoid cartilage, producing a shortening of the vocal cord, whereas in a posterior displacement the arytenoid cartilage presents a posterolateral position with a superior movement of the vocal process.…”

“…The anterior dislocation is characterized by an anteromedial and inferior displacement of body of the arytenoid cartilage, producing a shortening of the vocal cord, whereas in a posterior displacement the arytenoid cartilage presents a posterolateral position with a superior movement of the vocal process. In a review of 63 cases, Rubin et al [3] postulate that the posterior dislocations are more common than the anterior dislocation. A complete history of the patient is imperative in order to suspect the diagnosis.…”

“…Discrepancy in the height between the vocal folds must be assessed in addition to any internal traumatic injury to the larynx. Videostroboscopy allows a better visualization of the vocal cords length and the height of the vocal processes and therefore is an essential tool to help differentiate cricoarytenoid subluxation from vocal cord palsy [3,7]. A CT scan of the laryngeal skeleton can reveal changes in the cricoarytenoid joints in addition to changes in other laryngeal structures and is a useful exam to help reach the diagnosis [8].…”

“…The exact incidence of this condition is unknown because the immobility of the vocal fold may be confused with vocal fold palsy, therefore it is believed that the actual incidence is being underestimated [2,3]. Approximately 80 % of the cases are caused by a traumatic intubation of the airway [3].…”

Cricoarytenoid joint subluxation is rare condition. There are \200 cases reported in the English literature. The most frequent cause of this condition is a traumatic tracheal intubation which account for approximately 80 % of all cases. The most common symptoms are dysphonia and pain of the anterior region of the neck which appear after upper airway manipulation or cervical trauma. In this report we present a well-documented case of a 31 year old male that was referred to the outpatient clinic because of acute dysphonia and pain that appeared immediately after receiving a blow of a soccer ball. Diagnosis was suspected after patient reported the acute onset of symptoms after the traumatic event along with findings in flexible fiberoptic laryngoscopy and videostroboscopy. A CT scan of the larynx was done where the injury of the left cricoarytenoid joint was seen. The patient was informed of the condition and was given the option of surgical reduction or speech therapy. Speech therapy was done for 3 month and the patient was satisfied with the result, although the anatomical abnormality persisted. We reviewed the literature and we discuss the diagnosis process and possible treatment options.

Importance Arytenoid dislocation is a rare condition characterized by vocal fold immobility and is easily mistaken as recurrent laryngeal nerve paralysis. Objective To describe presenting features, multimodal diagnostic evaluation, and surgical outcomes following closed reduction (CR) of arytenoid dislocation. Design, Setting and Participants Prospective case series at a single academic medical center. Evaluation and treatment data were obtained from 22 consecutive patients with arytenoid dislocation over a 7-year period. Interventions Patients underwent direct laryngoscopy and CR of the dislocated arytenoid, with adjunct injection laryngoplasty or botulinum toxin administration in select cases. Main outcomes and measures Initial diagnosis was confirmed using flexible laryngeal endoscopy with stroboscopy, computed tomography, electromyography, and interoperative palpation. Arytenoid motion (primary outcome measure) and vocal function data (secondary outcome measures) were collected before treatment and up to 6 months after treatment. Results Key history features included emergent intubation, elective intubation and external laryngeal trauma. Sixteen patients (73%) had anterior and 6 patients (27%) had posterior dislocation. One patient experienced spontaneous recovery. Following CR, with or without adjunct therapy, 18 of the remaining patients (86%) exhibited arytenoid motion recovery with concomitant voice improvement. Recovery was sustained at 6 months after CR. Closed Reduction performed within 21 days of the presumed dislocation event was associated with a superior arytenoid motion recovery rate. Conclusions and Relevance These data represent the largest clinical series on arytenoid dislocation with complete vocal function data and follow-up at 6 months after CR. These findings also corroborate existing evidence for early surgical intervention.
