| Abstract |
|
Authors suggest new radiologic lateral view of upper airway which can simultaneously visualize whole length of upper airway for the preanesthetic evaluation. 1) The proper use of special wedge filter and removal of shoulder shadow from the tracheal ahadow were the two essentials for the imagification of the airway. 2) This view gives pretty images of upper respiratory tract ineluding epiglottis, vocal cord and tracheal passage. 3) The potential usefulness of the whole lengt lateral view of upper airway is thought to be promising in many fields. For example, measurement of length of variaus airway structure ia poseible by use of this view. In conclusion, this view is a noninvasive and inexpensive radiologic method as a approach to detect abnormalities of the larynx and trachea both before and after intubation. |
