I have been involved in instruction on the difficult airway for 14 years and have had numerous discussions with Dr. Archie BRain the LMA inventor. He feels that although there are many ways to insert the LMA the conventional, fully deflated remains the easiest method of insertion. I would agree with him. Additionally if you consider a LMA as a rescue device, partially inflating the LMA usually causes the epiglottis to fold over the laryngeal opening making intubation with a 6.0 MLT endotrachael tube or fiberoptic assisted trachael intubation difficult or impossible.
