Unanticipated difficult airway due to undiagnosed oropharyngeal stenosis: a case report

摘要

Unanticipated difficult airway is a challenging problem for anesthesiologists. Oropharyngeal stenosis (OPS) is a rare complication of upper airway surgery which may cause difficult airway. We present a patient whose postsurgical OPS was revealed during the induction of general anesthesia, and necessitated reschedule of surgery and tracheotomy. We also discuss the etiology and risk factors of postsurgical OPS.
