Killian's dehiscence
Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors(also see Pharyngeal pouch). It can be seen as a locus minoris resistentiae. Similar triangular area between circular fibres of cricopharyngeus and longitudinal fibres of esophagus is Lamier's triangle or Lamier-hackermann's area.
