title: Cricoid cartilage necrosis after arytenoidectomy in a previously irradiated larynx.
abstract: Several open and endoscopic surgical techniques are available to provide an adequate airway for patients with bilateral vocal cord paralysis. Transoral laser arytenoidectomy has repeatedly been reported to be a reliable and effective minimally invasive procedure for airway restoration. To our knowledge, there have been no previous reports of serious complications, other than poor vocal results, aspiration, and failed decannulation in individual patients, that have resulted from this intervention. We report a case in which arytenoidectomy led to severe complications and death. Prior irradiation is suspected to be a causative factor. To prevent such an outcome, we believe that operative settings should be chosen that avoid deep thermal injury of the laryngeal framework.
