Contact us: sales@gpianatomy.com


Zenker’s diverticulum, a pulsion diverticulum of the hypopharynx, is a rare lesion that occurs in older populations. Typically occurring between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle, it may also originate in other parts of the esophagus. It often presents with dysphagia.

Treatment of symptomatic lesions includes diverticulectomy with myotomy and endoscopic diverticulectomy.

Designed using MRI and CT imaging scans and the latest 3D printing technologies, in collaboration with Mayo Clinic.

About the Condition

The Pharynx & Esophagus

When you eat or drink, it moves from the mouth into the throat, or pharynx. From there, it enters the esophagus through the upper esophageal sphincter (UES) and travels to the stomach. The UES is also known as the cricopharyngeus muscle. When it works properly, it relaxes to allow food to pass into the esophagus and closes to prevent food from backing up into the throat.

What Is Zenker’s Diverticulum?

Zenker’s diverticulum is a pouch that forms in the back of the throat, most commonly in older adults. The pouch develops when the muscle that connects the throat and the esophagus, the cricopharyngeus muscle, is too tight. Pressure from the muscle causes a pouch to form in the tissue above it. Over time, food is unable to pass easily through the esophagus and is deposited in the pouch. Common symptoms include choking, regurgitation, bad breath and trouble swallowing.

How Is It Treated?

The condition may be treated with surgery, called a diverticulectomy. More commonly, it’s treated with a minimally invasive approach. The goal of treatment is to remove the pouch and relieve tightness in the throat, so that food can pass through unobstructed.

Benefits of 3D Printing

3D-printed anatomy models offer a variety of advantages for surgical planning, patient education and medical research, including:

∙ Greater accuracy and detail than traditional anatomical models. 3D-printed models are created from digital scans of a patient's anatomy, which ensures that they are as close as possible to an exact replica of real human anatomy.

∙ More versatility than traditional anatomical models. 3D-printed models can be customized to meet your specific needs, whether planning a complex surgical procedure, training with real patient data or facilitating personalized patient communication.

Not limited to standard manufacturing, 3DP provides the best opportunity to produce accurate models in natural organic shapes, sizes, and colors; creating the best representation of real human anatomy.
