A pharyngeal pouch is a pulsion diverticulum of the pharyngeal mucosa through Killian's dehiscence. Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the inferior constrictor muscle and the cricopharyngeus muscle. It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely.
