Congenital subglottic stenosis: diagnosis and management.

In contrast to the generally accepted concept, I have classified congenital subglottic stenosis in a different way. During the first months of life, the abnormality may be recognized by its frequent association with acute respiratory infections, providing the opportunity to recognize it once the infection has been controlled. I emphasize the role of the radiologic examination of the larynx for diagnosis and follow-up of this disorder and its different evolution from that of pure subglottic laryngitis. A comparison with subglottic laryngitis and laryngotracheobronchitis emphasizes the seriousness of this retardation in the normal development of the larynx.
