A rare congenital malformation characterized by either completely absent (agenesis), or severely underdeveloped (atresia) trachea. In both cases, the tracheal lumen is absent for at least a portion of its length, with no proximal-distal communication between the larynx and lower airways. Functionally and in terms of management, tracheal agenesis and tracheal atresia are equivalent.
