Anatomical terminology

Killian's dehiscence (also known as Killian's triangle, Laimer triangle, Laimer-Killian triangle, or Laimer-Haeckermann area) is a triangular area in the wall of the pharynx between the thyropharyngeal and cricopharyngeus of the inferior constrictor of the pharynx (also see Pharyngeal pouch).

Clinical significance[edit]

It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely to occur.[1]

Eponym[edit]

It is named after the German ENT surgeon Gustav Killian.[2]
