The upside-down intubating laryngeal mask airway: a technique for cases of fixed flexed neck deformity.

When the neck is fixed in extreme flexion, access to the windpipe becomes very difficult. The intubating laryngeal mask airway (ILMA) appears unsuitable for guiding the breathing tube into the windpipe in such cases because of its rigid, preformed shape. However, the ILMA introduced upside down may provide the answer, even if the mouth opening is smaller than normal.
