The oral route is used most commonly when intubating a patient because access to the larynx is easier and the skill is more easily learned. This should be the route of first choice to establish and secure the airway; alternative routes can be planned later.

2. There is less stable fixation where uncuffed tubes are used.
3. Oral and labial sores may develop after prolonged intubation.
