S u m m a r y: Despite advances achieved in the last decades postintubation subglottic stenosis remains a serious therapeutic problem in children. One of the possible surgical approaches is dilatation laryngotracheoplasty. The authors present in their paper their experience with postin- tubations stenosis in a 8-year-old boy. After failure of conservative treatment they performed a one-stage anterior laryngotracheoplasty with a dilatation graft of autologous cartilage from a rib. The postoperative course was complicated by a granulation process on account of which retrache- otomy had to be performed which protracted the patient’s dependence on a tracheostomic cannula by three monhts. One and a half year after operation the boy has no respiratory complaints.

        Key words: one-stage anterior dilatation laryngotracheoplasty, postintubation subglottic stenosis.
