Laryngeal mask airway ventilation is easy to use compared with endotracheal intubation, requires no stimulation of the glottis and trachea and does not affect the ciliary movement of the tracheal mucosa. Its prominent advantage is the elimination of mechanical stimulation to the tracheal larynx Laryngeal mask airways (LMA) are supraglottic airway devices. They may be used as a temporary method to maintain an open airway during the administration of anesthesia or as an immediate life-saving measure in a patient with a difficult or failed airway.
