“…Of note, 1 patient experienced spontaneous resolution of symptoms, which in the literature has been attributed to arytenoid repositioning during forceful laryngeal maneuvers such as coughing or emesis. 10,22 All 13 patients who underwent CR within 21 d of their presumed dislocation event experienced complete return of arytenoid motion, whereas 3 of 8 patients who underwent CR beyond 21 days of their presumed dislocation event had no return of function at 6 months after CR. These 3 patients were the only individuals in the study with an interval from presumed dislocation to attempted CR of more than 1 year; in 1 case the interval was approximately 17 years.…”

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.

“…The frequency of arytenoid cartilage dislocation related to direct laryngoscopy has been reported to be 0.023%. 5 The use of lighted stylet, 5 6 laryngeal mask airway 7 8 and McCoy laryngoscope 9 and cases of difficult intubation [10][11][12] have been reported to be associated with arytenoid cartilage dislocation. Cases of arytenoid cartilage dislocation with apparently straightforward tracheal intubation have also been reported.…”

Arytenoid cartilage dislocation caused by a double-lumen endobronchial tube

Following surgery requiring the use of a double-lumen endobronchial tube, a patient immediately complained of persistent severe hoarseness. On the third day after the operation, fibreoptic laryngoscopy revealed posterolateral dislocation of the left arytenoid cartilage. By the sixth day of the operation, a slight improvement was observed in the hoarseness without treatment and a spontaneous recovery of arytenoid cartilage dislocation was expected. The patient did not consent to surgical treatment, and therefore a conservative therapy was selected. Ten weeks after the operation, it was found that the dislocated left arytenoid cartilage had spontaneously repositioned and the patient regained his normal voice. The causes and treatment options are discussed.

Spontaneous Reposition of a Dislocated Arytenoid Cartilage

Abstract: We report a patient suffering from arytenoid cartilage dislocation after difficult tracheal intubation and the abrupt spontaneous reposition in the course of severe vomiting 1 month after the operation. Predisposing factors for the unusual reposition are discussed.
