We describe an alternative technique for difficult intubation using a fibrescope and a video camera system. The fibrescope attached to the video camera was passed nasally, which provided a view of the larynx on the monitor screen. Then the operator inserted a tracheal tube into the trachea orally using a second fibrescope or a stylet under video visual control. This technique permits a view of the tube passing through the vocal cords in patients who present difficulty in intubation.
