Laryngeal Mask Airway
The LMA™ laryngeal mask enables anaesthetists to channel oxygen or anaesthesia gas to a patient's lungs during surgery. It has an airway tube that connects to an elliptical mask with a cuff. When the cuff is inflated, the mask conforms to the anatomy with the bowl of the mask facing the space between the vocal chords. After correct insertion, the tip of the LMA™ laryngeal mask sits in the throat against the muscular valve that is located at the upper portion of the oesophagus.

“Vice, in its true light, is so deformed, that it shocks us at first sight; and would hardly ever seduce us, if it did not at first wear the mask of some virtue.”
