Open Approach to Pharyngeal Pouch and Cricopharyngeal Myotomy

Pharyngeal pouch (also termed Zenkers diverticulum) refers to a false pulsion diverticulum of the hypopharynx passing most commonly through Killian’s dehiscence [1]. It is most common in the eighth decade. The etiopathogenesis of pharyngeal pouch formation remains unclear, although most theories centre on cricopharyngeal dysfunction which could be initially associated with dysphagia and later with aspiration and regurgitation as a pouch forms.
