CT and virtual endoscopy findings in congenital laryngeal web.

Laryngeal web is a rare lesion resulting from incomplete recanalization of the primitive larynx. Because the extent of airway involvement affects surgical management, patients should be studied thoroughly before treatment. Although the diagnosis is based on the endoscopy findings in most of the cases, laryngoscopy may fail to show the subglottic extension of the disease. Virtual endoscopy may provide the information needed for surgery in such cases. Here, we report the computed tomography and virtual endoscopy findings in a 5-year-old child with a laryngeal web.
