[Congenital laryngeal atresia: apropos of a case].

A case of congenital laryngeal atresia in which the laryngeal lumen was obstructed by a soft, smooth protrusion is reported. Laryngeal stenosis was located at the glottic level and appeared as a protrusion reducing the laryngeal lumen to a few millimeters. The stenotic tissue consisted of striated muscle fibres cross-linked through their midlines.
