A condition in which the tongue tends to fall backward and obstruct the openings to the larynx and esophagus. The tongue is not swallowed and the term is inaccurate; nevertheless, it is occasionally used. The condition is due to excessive flaccidity of the tongue during unconsciousness. Airway control is achieved through one of the following maneuvers: forceful elevation of the chin and extension of the head during artificial respiration, in order to open the airway; or insertion of a mechanical airway device, such as an oropharyngeal airway, to push the tongue out of the airway.
