Simulation of KTP Laser–Based Zenker Diverticulotomy with a Porcine Model and Laryngeal Dissection Station

Simulation of KTP Laser–Based Zenker Diverticulotomy with a Porcine Model and Laryngeal Dissection Station

Zenker’s diverticulum is a rare cause of progressive dysphagia that is treated surgically. Potassium titanyl phosphate (KTP) laser–based diverticulotomy is one effective treatment. Developing a simulation model is helpful for rare conditions. Pigs have a natural hypopharyngeal pouch similar to a div...
