Core Tip

Core Tip: Postoperative upper airway obstruction after general anesthesia requires urgent airway intervention. Postoperative stridor is a common cause of laryngeal spasm, but functional vocal cord disorders may also be a cause. However, anesthesiologists may be unfamiliar with functional vocal cord disorders, and this may lead to inappropriate interventions. We present the case of a patient with post-extubation repetitive stridor who was postoperatively diagnosed with paradoxical vocal fold motion (PVFM) by an otolaryngologist and discuss the diagnosis and treatment of PVFM. Our case presentation showed that PVFM should be considered in the differential diagnosis of postoperative stridor.
