| Abstract: |
This case report describes a right arytenoid dislocation after emergency fiberoptic nasotracheal intubation in a patient with angioedema. The patient returned to the emergency department multiple times with classic symptoms of arytenoid dislocation, complicated by resultant postinjury laryngeal edema and poorly controlled laryngopharyngeal reflux. The arytenoid injury was not initially recognized, which delayed treatment. Several months later, intraoperative assessment was done because of continued symptoms sus- picious for laryngeal injury, resulting in a diagnosis of right cricoarytenoid joint fixation resulting from prior intubation trauma. Because of delayed diagnosis and treatment, severe cricoarytenoid joint scarring and fixation prevented repositioning of the arytenoid and improvement in laryngeal function. Discussion of this case includes a review of the anatomy and function of the arytenoid and cricoarytenoid joint, along with factors that increase and decrease joint stability and risk of injury. The etiology of arytenoid dislocation is described, along with suspected mechanisms of injury in anterior vs posterior and right vs left dislocations. Classic symptoms, the importance of early identification, and treatment options are also discussed. [ABSTRACT FROM AUTHOR] |
