The purpose of direct laryngoscopy is to achieve sight of the vocal cords, so that tracheal intubation can be performed under direct vision. The laryngoscope handle should be held in the left hand.

The first attempt at direct laryngoscopy should always be performed under optimal conditions.

Although it is desirable to see the entire length of the vocal cords, including the anterior commissure, tracheal intubation under vision can be achieved when only a portion of the vocal cords can be seen.

Successful direct laryngoscopy depends on achieving a line of sight (LOS) from the maxillary teeth to the larynx. Management of the tongue and epiglottis is central to successful direct laryngoscopy.
