Laryngoscopes are, simply put, devices that allow to view the larynx. The larynx can be looked at either directly or indirectly.
Devices for direct laryngoscopy essentially establish a direct line of sight between the eye of the practitioner and the larynx. Direct laryngoscopes include the typical handle and blade assemblies.
Indirect laryngoscopes on the other hand use camera or fiberoptic technology to view the larynx. These devices include, for example, videolaryngoscopes or optical stylets. Indirect laryngoscopes allow an 'around-the-corner' look at the larynx by moving the point of view downwards along the curved laryngoscope blade closer to the vocal chords.
