Tracheal intubation using a new CCD camera-equipped device: a report of two cases with a difficult intubation.

In two patients, one with Klippel-Feil syndrome and one with fibrous dysplasia of the maxilla, no part of the larynx could be visualized by direct laryngoscopy. In both cases, the use of an intubation device equipped with a charge-coupled device camera, the endotracheal intubation device (EID), allowed smooth tracheal intubation.
