Congenital laryngeal defects.
Embryologic disorders of the larynx are rare. The main symptoms are stridor and hoarseness, symptoms which in the newborn always necessitate further investigation. Both the laryngotracheo-esophageal cleft and the congenital laryngeal web are discussed in relation to the embryologic development of the larynx and to diagnosis and therapy. The use of the operating microscope is stressed.
