Direct laryngoscopy in children: rigid and flexible fiberoptic

Abstract

Examination of the child's larynx is mandatory in the management of pediatric airway problems. The techniques used to perform this examination have evolved over time and now present the airway specialist with choices that can be tailored to each specific situation. Traditionally, rigid direct laryngoscopy (RDL) has been used to evaluate the pediatric larynx. More recently, flexible fiberoptic laryngoscopy (FFL) has been used to visualize the child's airway. RDL and FFL each play a role in the evaluation of the pediatric larynx. Expertise with both techniques is mandatory for the otolaryngologist managing respiratory disorders in children. FFL has become our technique of choice to evaluate the pediatric larynx especially when airway dynamics are of concern. RDL remains the preferred technique when laryngeal/tracheal surgery is planned or establishment and protection of the airway with intubation or bronchoscopy is required.
