The authors report about the cases of two infants less than 5 weeks old, who presented with congenital subglottic stenosis and in whom a cricoid split produced good results. This procedure, which is classically reserved for difficult extubation of infants due to acquired subglottic stenosis, is compared with the other surgical techniques used in the congenital condition. It may be useful in the latter case owing to its simplicity and to the possibility of performing laryngoplasty later in case of failure.
