Zenker's diverticulum is a mucosal lined outpouching of pharynx through Lainert's space that causes dysphagia of the upper digestive tract. Multiples theories try to explain the acquired etiology of this entity, attributing its origin to a disfunction of pharynx-esophageal sphincter. A case of total larynguectomy with hypopharyngeal diverticulum and progressive dysphagia to solid food is presented. We analyze the etiopathogenic mechanisms and the definitive characteristics of this entity. We review mundial literature, being exceptional the fact of finding clinical manifestations in diverticulum of larynguectomized patients.
