| Anatomical terminology |
Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus (upper esophageal sphincter (UES)) and thyropharyngeus (Inferior pharyngeal constrictor muscle) which are the two parts of the inferior constrictors (also see Pharyngeal pouch). It can be seen as a locus minoris resistentiae (place of low resistance). A similar triangular area between circular fibres of the cricopharyngeus and longitudinal fibres of the esophagus is Lamier's triangle or Lamier-Hackermann's area.
Clinical significance
[edit source]It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely to occur.[1]
Eponym
[edit source]It is named after the German ENT surgeon Gustav Killian.[2]
