laryngotracheoesophageal cleft

(redirected from complete posterior laryngeal cleft)

laryngotracheoesophageal cleft

absence of fusion of the interarytenoid musculature or cricoid cartilaginous laminae of varying severity: type 1, submucous cleft of the interarytenoid muscles (known also as occult posterior laryngeal cleft or submucous laryngeal cleft); type 2, partial cricoid cleft (known also as partial posterior laryngeal cleft); type 3, total cricoid cleft (known also as laryngotracheoesophageal cleft or total cricoid cleft); and type 4, extension of the cleft into the trachea. Symptoms of this anomaly are similar to those of tracheoesophageal fistula.

laryngotracheoesophageal cleft

a cleft between the larynx and the upper trachea resulting from incomplete separation of these structures during embryonic development, with respiratory manifestations including respiratory distress with feeding, flaccid aryepiglottic folds, chronic cough, and increased oral secretions. It is frequently associated with other congenital anomalies of the respiratory system or GI tract. Complications include failure to thrive and recurrent aspiration pneumonia.
