Arytenoid subluxation is a rare laryngeal injury that may follow instrumentation of the airway and present as hoarseness (1), vocal fatigue (1), stridor (2), dysphagia (1), odynophagia (3) and sore throat (1).
A differential diagnosis of airway oedema, laryngospasm, vocal cord paresis and arytenoid subluxation was entertained.
A prospective study suggested an incidence of one arytenoid subluxation or less for every 1000 direct laryngoscopic intubations (0.
Patients with arytenoid subluxation primarily report hoarseness upon presentation (1,8.
Early treatment of arytenoid subluxation includes direct laryngoscopy and closed reduction of the subluxated arytenoid with the patient under general anaesthesia or under local anaesthesia with intravenous sedation.
