Abstract

The incidence of congenital stridor is on rise due to improved neonate and infant survival rate. The gold standard investigation for evaluation of stridor is rigid laryngotracheobronchoscopy, but this is invasive and requires general anesthesia. Flexible fibreoptic laryngoscopy, a relatively simple and less invasive procedure can be done under topical anaesthesia for evaluation of stridor. In this study, we have presented our experience of flexible laryngoscopy in children with congenital stridor, their results and management. Laryngomalacia was the commonest cause of stridor accounting for 80% of cases. 15% (6) patients required tracheostomy for relieving airway obstruction and 22.5% (9) patients required a definitive surgical procedure for correcting the cause. Flexible laryngoscopy is safe and gives a comprehensive analysis of airway including its dynamic functions. We also recommend flexible laryngoscopy as a frontline investigation for evaluation of stridor.
