Difficult intubation occurs when a limited view of the glottis at laryngoscopy makes tracheal tube placement difficult.

Question: What are the structures you are likely to see at laryngoscopy?

Answer

Difficult intubation occurs when a limited view of the glottis at laryngoscopy makes tracheal tube placement difficult.

Question: What are the structures you are likely to see at laryngoscopy?

Answer: Most of the glottis (Fig 1) can be seen in the majority of cases.

Commonly, however, the view of the glottis is more limited (Fig 2). In some patients the view may be even more limited (Fig 3).

In a few patients no part of the glottis or epiglottis is seen, only the base of the tongue is visible (Fig 4).
