Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...
used in direct laryngoscopy; video link: Jobson Horne's probe with ring curette: to access or clean the external ear: Tuning forks: for various clinical tests of hearing loss; vibration sense test Pritchard's politzerization apparatus: video link: Aural/Ear syringe: used to flush out anything like ear wax or foreign bodies from the external ear
In the prehospital emergency setting, digital intubation may be necessitated if the patient is in a position that makes direct laryngoscopy impossible. For example, digital intubation may be used by a paramedic if the patient is entrapped in an inverted position in a vehicle after a motor vehicle collision with a prolonged extrication time.
Limitations of video laryngoscopy exist and prevent the exclusive use of this method over direct laryngoscopy. Excessive blood and saliva in the airway can cover the camera lens on the video laryngoscope and obscure effective visualization of the anatomy, preventing effective intubation attempts.
A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult bag mask ventilation.

In 1913, Chevalier Jackson (1865–1958) was the first to report a high rate of success for the use of direct laryngoscopy as a means to intubate the trachea. [126] Jackson introduced a new laryngoscope blade that had a light source at the distal tip, rather than the proximal light source used by Kirstein. [127]
The Cormack–Lehane system classifies views obtained by direct laryngoscopy based on the structures seen. It was initially described by R.S. Cormack and J. Lehane in 1984 as a way of simulating potential scenarios that trainee anaesthetists might face.
