Management of subglottic stenosis in infancy and childhood.

During the 12-year period between June 1987 and June 1999, 141 children underwent curative treatment for subglottic laryngeal stenosis at La Timone Children's Hospital in Marseille, France. Ninety-six children (68%) were under the age of 5 years; 106 (75%) presented with acquired stenosis and 93 had narrowing involving over 70% of the subglottic lumen. Endoscopic laser surgery was performed in 25 cases and open surgery in 116. Open surgical techniques included laryngotracheoplasty with autologous cartilage interposition in 83 cases, laryngotracheal split in 22, and cricotracheal resection in 11. After decannulation, 132 children (94%) were able to breathe normally through the upper airway. Perspectives for development of new techniques and improvement of conventional methods are discussed.
