Abstract
Postcricoid vascular abnormalities are rare causes of chronic dysphagia and dyspnea in infants and children. A postcricoid cushion is a mass that becomes obvious when children cry because of venous flux dilation in the postcricoid lesion. The condition can present as a sucking or respiratory disorder, attributable to laryngeal stenosis caused by venous pressure imparted by the mass. The epidemiology and pathophysiology of a postcricoid cushion are poorly known; many cases are asymptomatic and many are often diagnosed as hemangiomas or vascular malformations. Herein, we report a case of an infant in whom postcricoid cushion was diagnosed by laryngoscopy under sedation, considering the unique pressure-dependent characteristics of the lesion.
