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 (40).

[1] the primary disadvantage and greatest concern with the use of the LAM is the inability to isolate the airway and to protect against the risk of aspiration. Indeed, the LAM has been shown to form a direct conduit between the laryngeal inlet and esophagus by enclosing both.

Its introduction into clinical practice coincided with the increasing number of laparoscopic procedures in general surgery and gynecologic practice. However, the use of classic type laryngeal mask (LMA Classic) in laparoscopy remains controversial due to the increased risk of regurgitation and pulmonary aspiration.

The LMA-ProSeal™ is a new laryngeal mask airway with a rear cuff and drainage tube that allows a higher seal pressure than the LMA-Classic™ for the same intra-cuff pressure, and it permits drainage of gastric secretions and access to the alimentary tract.
