[The laryngeal cyst of the new born (author's transl)].

Only 30 cases of cysts of the ventricular cord in the new born baby have been published. Because of the respiratory stridor one third of the cases died soon or later. The other 2/3 were treated by endolaryngeal procedures. With a case of a new born suffering from a large cyst of the ventricular cord the author demonstrates the possible danger and inefficiency of different endolaryngeal procedures. Only the external operation through the thyrohyoid membrane with complete removal of the cyst - without tracheotomy--resulted in permanent cure.
