Flexible fiberoptic intubation was first described in 1967 and has since become a mainstay in intubations of the difficult airway. The first flexible fiberoptic scope for ETTs greater than 4.5 mm ID was developed in the early 1970s. In the late 1980s, an ultrathin flexible fiberoptic laryngoscope was introduced, allowing intubation with ETTs as small as 2.5 mm ID. Multiple authors have since described the flexible fiberoptic bronchoscope’s safe and effective use in both normal and difficult pediatric airways. Others have described a variety of intubating methods using the flexible fiberoptic bronchoscope. The flexible fiberscope is a device born of innovations in fiberoptic technology.
