Foreign Bodies In The Larynx And Tracheobronchial Tree
Category: FOREIGN BODIES IN THE LARYNX AND TRACHEOBRONCHIAL TREE
Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery
The protective reflexes preventing the entrance of foreign bodies into
the lower air passages are: (1) The laryngeal closing reflex and (2)
the bechic reflex. Laryngeal closing for normal swallowing consists
chiefly in the tilting and the closure of the upper laryngeal orifice.
The ventricular bands help but slightly; and the epiglottis and the
vocal cords little, if at all. The gauntlet to be run by foreign
bodies entering the tracheobronchial tree is composed of:
2. Upper laryngeal orifice.
3. Ventricular bands.
4. Vocal cords.
5. Bechic blast.
The epiglottis acts somewhat as a fender. The superior laryngeal
aperture, composed of a pair of movable ridges of tissue, has almost a
sphincteric action, in addition to a tilting movement. The ventricular
bands can approximate under powerful stimuli. The vocal cords act
similarly. The one defect in the efficiency of this barrier, is the
tendency to take a deep inspiration preparatory to the cough excited
by the contact of a foreign body.
