Congenital anterior glottic webs: a retrospective review of 59 cases with management and outcomes

Congenital anterior glottic webs are rare anomalies seen in disrupted embryogenesis of the vocal cords. The development of these webs still remains unclear and are thought to be associated with abnormal development of either the vacuolization of the epithelial lamina, the laryngeal caecum or the pharyngotracheal duct (1). They present with a spectrum of symptoms and signs which can range from an altered cry to severe airway obstruction (2). They are characterised by their position (anterior or posterior), involvement of the subglottic area and whether it is congenital or acquired (3). Seymour Cohen proposed an internationally accepted staging system for characterising anterior glottic webs relying on the Original Article
