Chapter 34 : Stenosis of the larynx

Stenosis of the larynx is more frequent than tracheal stenosis; in a review of 752 cases of stridor seen at The Hospital for Sick Children, Great Ormond Street, London, laryngeal pathology accounted for 88% of the cases (Evans, 1986). The major cause of airway obstruction was as a result of congenital anomalies of the larynx and trachea. Holinger (1980) noted in his review of 219 patients with stridor, that it was caused by a congenital anomaly of the larynx or trachea in 87.2% of the patients. Congenital laryngeal anomalies are discussed in Chapter 26.
