The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .

Magill forceps are angled forceps used to guide a tracheal tube into the larynx or a nasogastric tube into the esophagus under direct vision. [1] They are also used to remove foreign bodies . [ 1 ] These forceps are named after the Irish-born anaesthetist Ivan Magill .
Sir Robert Macintosh (1897–1989) introduced a curved laryngoscope blade in 1943; [131] the Macintosh blade remains to this day the most widely used laryngoscope blade for orotracheal intubation. [10] Between 1945 and 1952, optical engineers built upon the earlier work of Rudolph Schindler (1888–1968), developing the first gastrocamera. [132]
An endoscopy can examine the esophagus, stomach and part of the small intestines, and CT scans may be used to check for tumors or structural abnormalities in the head, neck or chest.
In 1913, Chevalier Jackson was the first to report a high rate of success for the use of direct laryngoscopy as a means to intubate the trachea. [69] Jackson introduced a new laryngoscope blade that had a light source at the distal tip, rather than the proximal light source used by Kirstein. [70]
