[Tracheobronchial dyskinesia of the newborn infant and infant].

Basing on 57 own observations the pathophysiology and clinical phenomenology of the different forms (tracheobronchial collaps, tracheobronchial prolaps) of tracheobronchial dyskinesia in newborn and infants are described. The tracheo bronchial collaps apparently prevails at this early age of life. Prognostically it is assessed most favourable. Contrarely to the tracheobronchial prolaps it generally does not need a thorough going treatment and disappears until the end of the second year of life nearly in all cases. Indications are given as the most rational therapeutical behaviour in both phenomenological forms of the tracheobronchial dyskinesia in newborn and infants.
