Hypopharyngeal Diverticulum: Toward a Unified Understanding of Its Etiopathogenesis

We report using laser endoscopy to divide the inter-diverticular septum followed by transmucosal cricopharyngeus myotomy. Presentation of a rare, bilobed diverticulum emphasizes the importance of the midline prevertebral raphe in anchoring the pharyngeal constrictor muscl es with respect to the CPM. This lends support to the hypothesis that the etiopathogenesis of ZD is multifactorial while guiding us to a unified understanding of ZD.
