Synonym: Zenker's diverticulum
A pharyngeal pouch is a pulsion diverticulum, or false diverticulum, located dorsally at the wall between the pharynx and oesophagus.1 This area is known as Killian's triangle or dehiscence and is a region of relative weakness. It is a herniation between the thyropharyngeus and cricopharyngeus muscles that are both part of the inferior constrictor of the pharynx.
