text: # 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.
  
  ## Clinical significance
  
  It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely to occur.
  
  ## Eponym
  
  It is named after the German ENT surgeon Gustav Killian.
