Figure 3. Danger Triangle Concept
e danger triangle concept is applicable to ablation at the level of the upper tracheal rings and
cricothyroid joint. In the lower neck, the concept of a ''danger zone'' is more appropriate as the
recurrent laryngeal nerve is oen laterally placed at these levels, especially on the right.
CCA, common carotid artery; TR, trachea.
