The role of fibreoptic laryngoscopy in infants with stridor.
Stridor in infants may be potentially serious and would require further investigations in all cases. Laryngomalacia is the most common cause of congenital stridor. This is a self-limiting condition with a good prognosis but other causes of stridor should be excluded to enable the surgeon to plan further intervention if needed. Traditionally microlaryngoscopy and bronchoscopy under a general anaesthetic is performed to evaluate the airway. We have investigated the use of the flexible fibreoptic laryngoscope under local anaesthetics in infants with inspiratory stridor. The procedure was performed in the day surgery unit on a non-fasting, non-sedated child. A retrospective analysis of procedures performed between January 1998 and August 1999 was carried out. Of the 43 patients studied, laryngomalacia was diagnosed in 35, vocal cord palsies in six and two infants had a normal larynx. There were no complications during the procedure and only one child required further intervention. The results showed that the combination of fibreoptic laryngoscopy under local anaesthetic with follow-up is a safe, effective and cost effective method of assessing stridor in this group of patients.
