A case of cricoarytenoid subluxation secondary to endotracheal intubation and documented by computed tomography (CT) and electromyography (EMG) is reported. Successful endoscopic reduction of the displaced arytenoid is confirmed by CT. The normal anatomy and physiology of the cricoarytenoid joint is presented and the literature regarding this rarely reported injury is reviewed. Based on this review and the case reported, a treatment plan is proposed.

Arytenoid cartilage dislocation can occur as a complication of tracheal intubation and laryngeal trauma, but its occurrence with indirect video laryngoscopy has not been reported. This paper reports anterior arytenoid dislocation occurring after nasotracheal intubation performed under indirect laryngoscopy using a video laryngoscope (McGRATH MAC; Medtronic). The dislocation is presumed to have resulted from the laryngoscope blade being initially inserted too deeply and applying pressure to the posterior aspect of the left cricoarytenoid joint.

To investigate the reduction effect of hoding cricoarytenoid joint reduction with visual laryngoscope under intravenous anesthesia. The therapeutic effects of 40 patients with arytenoid dislocation(AD)treated by closed reduction in the single center from January 2020 to September 2021 were retrospectively analyzed, including 21 males and 19 females, median age 48 years. The etiology, symptoms, preoperative evaluation methods, reduction mode, reduction times, and the recovery of arytenoid cartilage movement and sound after reduction were evaluated and analyzed.

Airway interventions commonly present with self-limiting throat pain and hoarseness of voice. Persistent hoarseness is rare and should be evaluated for serious complications. Cricoarytenoid injuries may present as vocal cord palsies which need careful evaluation.

Objective: The diffusion characteristics of water molecules were measured in the vocal folds of canines exhibiting unilateral vocal fold paralysis and unilateral cricoarytenoid joint dislocation. These characteristics were used in conjunction with a histological examination of the microstructural changes of vocal fold muscle fibers to explore the feasibility of diffusion tensor imaging (DTI) in distinguishing unilateral vocal fold paralysis and unilateral cricoarytenoid joint dislocation as well as evaluating microstructural changes.
Methods: Ten beagles were randomly divided into three groups: four in the unilateral vocal fold paralysis group, four in the unilateral cricoarytenoid joint dislocation group, and two in the normal group.
