In this article, we present a rare case which was diagnosed as Zenker’s diverticulum that was treated with external approach by performing cricopharyngeal myotomy and diverticulectomy. Zenker’s diverticulum occurs by herniation of the pharynx mucosa and submucosa from the weakened area between the cricopharyngeus and the inferior constructor muscles, because of the increased pressure created by the spasm of the upper esophageal sphincter. It is usually seen in 7-8th decades of life and more common among men. Patients usually present with complaints of dysphagia, odynophagia, regurgitation, halitosis, and chronic cough. Currently, treatment for Zenker’s diverticulum has been mostly defined, however it has not determined precisely. The purpose of the treatment is to create a uniform flow in the lumen by preventing the diverticulum from being a reservoir. Today, endoscopic approach is frequently preferred because of low complication rates and operation times and short hospital stay. However, some authors also advocate that external approach should be applied with greater success rates for a large diverticulum and in patients who can not undergo endoscopy. In determining the treatment, the preference of the doctor, the patient’s expectation, general conditions and possibilities should be considered.
