Final answer:
Zenker's (pharyngoesophageal) diverticulum is caused by a pouch forming in the pharyngeal mucosa due to muscle weakness in the pharyngeal wall. Factors that contribute to its development include age, gender, and certain conditions. Treatment options include lifestyle changes, medication, and surgery.
Step-by-step explanation:
Zenker's (pharyngoesophageal) diverticulum is caused by a pouch forming in the pharyngeal mucosa, which is the lining of the throat. This pouch is formed by a weakness in the muscles of the pharyngeal wall, allowing it to bulge outward, and it is typically located just above the upper esophageal sphincter.
Factors that contribute to the development of Zenker's diverticulum include age, male gender, and certain conditions that cause increased pressure in the throat, such as difficulty swallowing, gastroesophageal reflux disease (GERD), and neurological disorders.
Treatment options for Zenker's diverticulum include lifestyle changes, medication, and surgical intervention.
