Pioneers of laryngoscopy: indirect, direct and video laryngoscopy.

Airway management is one of the core skills of the anaesthetist and various techniques of airway management have developed over many years. Initially, the only view of the glottis that could be obtained was an indirect view (indirect laryngoscopy). Late in the 19th century, a direct view of the glottis was obtained via various direct laryngoscopes. Currently, in the early 21st century, there has been a return to indirect laryngoscopy via videolaryngoscopy using a videolaryngoscope. The aim of this paper is to give a historical overview of the development of both direct and indirect laryngoscopy.
